What are the solutions for x to the equation (x-3)(x+8)=0

Answer:

The sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is t2 = 4 and recursive definition is tn+1 = 2 tn - 2 ⇒ 4th answer

Step-by-step explanation:

* Lets revise the recursive formula

1. Determine if the sequence is arithmetic (Do you add, or subtract, the

  same amount from one term to the next?)

2. Find the common difference. (The number you add or subtract.)

3. Create a recursive formula by stating the first term, and then stating

   the formula to be the previous term plus the common difference.

   a1 = first term;

   an+1= an + d

- Where:

# a1 = the first term in the sequence

# an = the nth term in the sequence  

# an+1 = the term after the nth term  

# n = the term number

# d = the common difference.

* Now lets solve the problem

∵ The recursive definition is tn+1 = 2 tn - 2 and t2 = 4

- Look to the answer we have three answer with second term = 4,

 1st , 2nd and 4th

- Lets find the 1st term

∵ t2 = 2 t1 - 2

∵ t2 = 4

∴ 4 = 2 t1 - 2 ⇒ add 2 to the both sides

∴ 6 = 2 t1 ⇒ divide the two sides by 2

∴ t1 = 3

- We have two answer with first term = 3, 2nd and 4th answers

* Lets find the third term

∵ t3 = 2 t2 - 2

∵ t2 = 4

∴ t3 = 2 (4) - 2 = 8 - 2 = 6

∴ The 4th answer has the third term = 6

* The 4th sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is

 t2 = 4 and recursive definition is tn+1 = 2 tn - 2

If angle g measures 117º, what is the measure of supplementary angle h?

Angle g and angle h are the Supplementary angles. Then the measure of the angle ∠h  will be 63°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

If angle g measures 117º.

Then the measure of angle h will be

We know that angle g and angle h are the Supplementary angles. Then we have

∠g + ∠h = 180°

117° + ∠h = 180°

         ∠h = 63°

Answer:

x=5

Step-by-step explanation:

We can solve this using the Pythagorean theorem

[tex]13^2-12^2=x^2\\\\x=\sqrt{169-144} \\\\x=\sqrt{25} \\\\x=5[/tex]

It should be 5. You would need to use the Pythagorean theorem, a^2 + b^2 = c^2 to find the length of the missing side. So it would be x^2 + 144=169, which leads to 169-144 = 25. Then you would need to get the square root of 25, which is 5. I hope that helps.

A horizontal shift happens when you add or subtract a value from the input value of x.

The answers are:

h(x) = 3 ln(x + 3) + 1

r(x) = −3 ln(x + 1) + 3

p(x) = ln(x + 2) − 2

Answer:

h(x) = 3 ln(x + 3) + 1

r(x) = −3 ln(x + 1) + 3

p(x) = ln(x + 2) − 2

Step-by-step explanation:

The parent function given to us is: [tex]f(x)=\ln x[/tex].

A horizontal translation to the left k units is of the form [tex]y=\ln (x+k)[/tex].

This implies that;

h(x) = 3 ln(x + 3) + 1, is a horizontal translation to the left by 3 units.

r(x) = −3 ln(x + 1) + 3, is a horizontal translation to the left by 1 unit.

p(x) = ln(x + 2) − 2, is a horizontal translation to the left by 2 unit.

Answer:

Step-by-step explanation:

To find the y-coordinate points we need to evaluate the function for all the [tex]x[/tex] values in the table. In other words, we need to replace [tex]x[/tex] with each value in our given function and simplify.

- For x = 0

[tex]f(x)=(x-2)^2-5[/tex]

[tex]f(0)=(0-2)^2-5[/tex]

[tex]f(0)=(-2)^2-5[/tex]

[tex]f(0)=4-5[/tex]

[tex]f(x)=-1[/tex]

Since [tex]x=0[/tex] and [tex]y=-1[/tex], our first point is (0, -1)

- For x = 1

[tex]f(x)=(x-2)^2-5[/tex]

[tex]f(1)=(1-2)^2-5[/tex]

[tex]f(1)=(-1)^2-5[/tex]

[tex]f(1)=1-5[/tex]

[tex]f(x)=-4[/tex]

Our second point is (1, -4)

- For x = 2

[tex]f(x)=(x-2)^2-5[/tex]

[tex]f(2)=(2-2)^2-5[/tex]

[tex]f(2)=(0)^2-5[/tex]

[tex]f(x)=-5[/tex]

Our third point is (2, -5)

- For x = 3

[tex]f(x)=(x-2)^2-5[/tex]

[tex]f(3)=(3-2)^2-5[/tex]

[tex]f(3)=(1)^2-5[/tex]

[tex]f(3)=1-5[/tex]

[tex]f(x)=-4[/tex]

Our fourth point is (3, -4)

- For x = 4

[tex]f(x)=(x-2)^2-5[/tex]

[tex]f(4)=(4-2)^2-5[/tex]

[tex]f(4)=(2)^2-5[/tex]

[tex]f(4)=4-5[/tex]

[tex]f(x)=-1[/tex]

Our fifth point is (4, -1)

Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.

The expression 5x + 5 ( x-3y ) + 1/2 (4x - 6y) simplifies to 12x - 18y by distributing the multiplication over addition, combining like terms, and checking the answer for reasonableness.

To simplify the algebraic expression 5x + 5 ( x-3y ) + ½ (4x - 6y), let's start by distributing the multiplication over addition for each term inside the parentheses:

Multiply 5 by each term inside the first set of parentheses: 5 × x and 5 × (-3y), which gives us 5x - 15y.

Multiply ½ by each term inside the second set of parentheses: ½ × 4x and ½ × (-6y), resulting in 2x - 3y.

Now, combine the like terms:

The x-terms: 5x + 5x + 2x = 12x.

The y-terms: -15y - 3y = -18y.

So, the expression in standard form is 12x - 18y.

Lastly, we should check the answer to see if it is reasonable:

No like terms are left to combine.

The coefficients are summed up correctly.

The expression is simplified as much as possible.

Solve for x: (2x + 40)° = (3x - 85)°. The solution is x = 125.

To find the value of x, you can set the expressions for the angles equal to each other since the two lines are parallel and corresponding angles are equal.

The given angles are:

- Line p: [tex]\(2x + 40\)[/tex] degrees

- Line q: [tex]\(3x - 85\)[/tex] degrees

Set them equal to each other and solve for x:

[tex]\[ 2x + 40 = 3x - 85 \][/tex]

Combine like terms:

[tex]\[ 40 + 85 = 3x - 2x \][/tex]

[tex]\[ 125 = x \][/tex]

So, the value of x is 125 degrees.

The complete question is here:

if line p is (2x+40)°and line q is (3x-85) what is the value of x​

The value of ( x ) is [tex]\( 125^\circ \)[/tex].

To find the value of ( x ), we can use the properties of parallel lines cut by a transversal. When two parallel lines are cut by a transversal, alternate interior angles are congruent.

Given:

- Angle [tex]\( 2x + 40^\circ \) and angle \( 3x - 85^\circ \)[/tex] are alternate interior angles.

So, we can set up an equation:

[tex]\[ 2x + 40^\circ = 3x - 85^\circ \][/tex]

Let's solve for ( x ):

[tex]\[ 2x - 3x = -85^\circ - 40^\circ \][/tex]

[tex]\[ -x = -125^\circ \][/tex]

To isolate ( x ), we divide both sides by -1:

[tex]\[ x = \frac{-125^\circ}{-1} \][/tex]

[tex]\[ x = 125^\circ \][/tex]

So, the value of ( x ) is [tex]\( 125^\circ \)[/tex].

complete question given below:

In the diagram, parallel lines P and Q are cut by transversal R.

(2x + 40°

(3x - 85)°

What is the value of x?

The following system of equations has only one solution, which is (2,0), because you can use the method of substitution to find the value of x and if it has multiple solutions.

y = x - 2

y = - x + 2

x - 2 = - x + 2

2x = 4

x = 2 (substituting this back into the equation)

y = 2 - 2

y = 0

Step-by-step explanation:

Forgive me if im wrong.

the only equation that seems to describe the pattern is:

[tex]\( b = a - 5 \)[/tex]. Therefore, option C is correct

To determine whether the given equations can describe the pattern in the table, we need to look at the values in the table and see if they satisfy the equations. However, the provided image is not completely clear, and it seems like part of the table or the values might be missing.

From what is visible in the image, it seems we have a table with two columns labeled 'a' and 'b', with 'a' taking on values from 5 to 9 and 'b' from 0 to 4. We need to check if the equations given describe the relationship between 'a' and 'b' according to the table.

The equations given are:

1. [tex]\( b + a = 5 \)[/tex]

2. [tex]\( b = a + 5 \)[/tex]

3. [tex]\( b = a - 5 \)[/tex]

4. [tex]\( a = b - 5 \)[/tex]

Without the complete table, we can't perform a full analysis, but we can explain how you would generally approach this:

- For equation 1 [tex](\( b + a = 5 \))[/tex], check if the sum of each pair of 'a' and 'b' equals 5.

- For equation 2 [tex](\( b = a + 5 \))[/tex], check if 'b' is always 5 more than 'a'.

- For equation 3 [tex](\( b = a - 5 \))[/tex], check if 'b' is always 'a' minus 5.

- For equation 4 [tex](\( a = b - 5 \))[/tex], check if 'a' is always 'b' minus 5.

Given the values for 'a' and 'b' in the table:

a | 5 | 6 | 7 | 8 | 9

b | 0 | 1 | 2 | 3 | 4

We can analyze each equation to see if it describes the pattern in the table.

1. [tex]\( b + a = 5 \)[/tex]

Let's check if the sum of 'a' and 'b' equals 5 for each pair:

- For [tex]\( a = 5 \), \( b = 0 \): \( 5 + 0 = 5 \)[/tex] (True)

- For [tex]\( a = 6 \), \( b = 1 \): \( 6 + 1 = 7 \)[/tex] (False)

- Since it is false for [tex]\( a = 6 \), \( b = 1 \)[/tex], we can already conclude that this equation does not describe the pattern.

2. [tex]\( b = a + 5 \)[/tex]

Let's check if 'b' equals 'a' plus 5:

- For [tex]\( a = 5 \), \( b = 0 \): \( 5 + 5 = 10 \)[/tex] (False)

- Since it is false for [tex]\( a = 5 \), \( b = 0 \)[/tex], this equation does not describe the pattern.

3. [tex]\( b = a - 5 \)[/tex]

Let's check if 'b' equals 'a' minus 5:

- For [tex]\( a = 5 \), \( b = 0 \): \( 5 - 5 = 0 \)[/tex] (True)

- For [tex]\( a = 6 \), \( b = 1 \): \( 6 - 5 = 1 \)[/tex] (True)

- Continuing this pattern, this equation seems to be true for all given pairs of 'a' and 'b'.

4. [tex]\( a = b - 5 \)[/tex]

This is not likely to be true since subtracting 5 from 'b' would result in negative numbers, which are not present in the 'a' values.

From the analysis, the only equation that seems to describe the pattern is:

[tex]\( b = a - 5 \)[/tex]

Let's confirm that this equation is true for all pairs of 'a' and 'b'.

The equation [tex]\( b = a - 5 \)[/tex] holds true for all pairs of 'a' and 'b' values in the table. Therefore, this equation correctly describes the pattern in the table.

(x + 2)^2 gives a duplicate (multiplicity 2) root. (because (x + 2)^2 = 0 so x = -2 multplicity 2)

(x - 4) gives one root of 4.

(x + 1)^3  gives x = -1 with multiplicity 3.

Answer:

-2 with multiplicity 2, 4 with multiplicity 1, and -1 with multiplicity 3.

Step-by-step explanation:

The given polynomial function is: [tex]f(x)=(x+2)^2(x-4)(x+1)^3[/tex].

To find the roots of this polynomial, we equate each factor to zero.

This implies that;

i. [tex](x+2)^2=0[/tex], [tex]\implies x=-2[/tex], the multiplicity of this root is 2, because the factor repeats twice

ii.  [tex]x-4=0[/tex], [tex]\implies x=4[/tex], the multiplicity of this root is 1, because the factor repeats once.

ii.  [tex](x+1)^3=0[/tex], [tex]\implies x=-1[/tex], the multiplicity of this root is 3, because the factor repeats three times.

Answer:

The number of messages sent by Justin was [tex]180\ messages[/tex]

The number of messages sent by David was [tex]270\ messages[/tex]

Step-by-step explanation:

Let

x-----> number of messages sent by Justin

y----> number of messages sent by David

we know that

[tex]\frac{x}{y}=\frac{8}{12}[/tex]

[tex]x=\frac{8}{12}y[/tex] ----> equation A

[tex]x+y=450[/tex] -----> equation B

substitute equation A in equation B and solve for y

[tex]\frac{8}{12}y+y=450[/tex]

[tex]\frac{20}{12}y=450[/tex]

[tex]y=450*12/20=270\ messages[/tex]

Find the value of x

[tex]x=\frac{8}{12}(270)=180\ messages[/tex]

therefore

The number of messages sent by Justin was [tex]180\ messages[/tex]

The number of messages sent by David was [tex]270\ messages[/tex]

Answer:

Step-by-step explanation:

Part A: Company A charges $6 for a window and $12 for a service clean. If you add that up it would be 6 + 12 =18 so company A would be making $18 per customer. Company B charges $15 + $5 for a whole cleaning which would make them $20 per customer. That is better then $18 so business B would be making more money.

Part B: For cleaning 8 windows company B would charge less because 8 x 5 = $40 for all the windows and company A would be charging $6 for a window which is more so 8 x 6 = 48. Company B charges less.

Part C: Company B charges 5 dollars for thier services on windows as Company A charges 6. You would be saving a dollar by buying at company B.

C. 35 men

EXPLANATION

Let m represent the number of men needed and d represent the number of days.

From the question,the number of men needed varies inversely to the time needed to complete the project.

We can write the inverse variation equation.

[tex]m = \frac{k}{d} [/tex]

where k is the constant of variation.

When m=28, d =90.

We substitute these values into the variation equation to determine the value of k.

[tex]28 = \frac{k}{90} [/tex]

[tex]k = 90 \times 28[/tex]

[tex]k = 252[/tex]

Now the equation becomes:

[tex]m= \frac{2520}{d} [/tex]

When d=72,

[tex]m = \frac{2520}{72} [/tex]

[tex]m = 35[/tex]

Therefore he needs to have 35 men working.
