Answer:

x=2                x=-3

Step-by-step explanation:

4x2+3x=24-x

Subtract 24 from each side

4x^2 +3x -24 = 24-24 -x

4x^2 +3x -24 = -x

Add x to each side

4x^2 +3x+x -24 = -x+x

4x^2 +4x -24 = 0

Factor out a 4

4(x^2 +x -6) = 0

Divide by 4

x^2 +x -6 =0

Factor

What 2 numbers multiply to -6 and add to 1

-2*3 = -6

-2+3 =1

(x-2) (x+3) =0

Using the zero product property

x-2 =0            x+3 =0

x-2+2=0+2    x+3-3=0-3

x=2                x=-3

Answer:x=-3 , x = 2

Step-by-step explanation:

First move the expression ( 24-x) to the left.

This gives us 4x^2+3x+24-x.

Collect the like terms which gives us 4x^2+4x+24

4x^2+4x-24 = 0.  Divide both sides by 4.

x^2 + x-6 = 0

Factorise the expression so you get (x+3)(x-2)=0

Solve the equations x+3 = 0 and x-2=0

The final solutions are x=-3 and x=2.

and pi is adding to the x, so it is a phase shift.

Answer:

4

Step-by-step explanation:

The median is the middle, since the amount of data is an even number we need to add up the third number and fourth number. These are 3 and 5 respectively. Adding these up gives up 8. Dividing this by 2 is 4.

The inequality x - 7 > -20 is solved by adding 7 to both sides, resulting in x > -13. The graph of this inequality has an open circle at -13 with shading to the right.

To solve the inequality x - 7 > -20, you want to isolate the variable x on one side. You can do this by adding 7 to both sides of the inequality:

x - 7 + 7 > -20 + 7

x > -13

So, the solution to the inequality is x > -13. To graph this solution on a number line, you would draw an open circle at -13 and shade to the right, indicating that x can be any value greater than -13 but not including -13 itself.

(-71+1) + 0 = (-71+1)

This is because the whole equation involves addition thus it is an example of associative property of addition

Answer:

(-71 + 1) + 0 = (-71 +1)

Step-by-step explanation:

Given 3 numbers: a,b,c

Associative property of addition: (a + b) + c = a + (b + c)

On this case: a= -71

b = 1

c = 0

(a + b) + c = (-71 + 1) + 0 = -70 + 0 = -70

(-71 + (1 + 0)) = (-71 + 1) = -70

Both the sums are equal to -70 and hence the associative property of addition for the three numbers a= -71, b = 1, c= 0 holds.

All the other options in the question contain a reference to variable i and does not have the same three values a,b,c on both sides of the equality. So they do not represent the associative property.

Answer:

Age of Jacob is 10 years.

Step-by-step explanation:

Let the age of Jacob = x years and age of Kinsley = y years

Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"

y = 2x - 7

By second statement " Kensley is 13 years old "

y = 3 years

By putting y = 13 years in the equation

13 = 2x - 7

2x = 13 + 7

2x = 20

x = [tex]\frac{20}{2}[/tex] = 10 years

Therefore, age of Jacob is 10 years.

Answer:

32028.8 ounces

Step-by-step explanation:

We are given that there are 908 kilograms of of trial mix are in a bag and we are to find the number of ounces of the same amout of mix in the bag.

For that, we will use the ratio method.

We know that, 1 kg = 35.274, so:

[tex] \frac { 1 k g }{908kg} =\frac{35.274 oz}{x}[/tex]

[tex]x=32028.8[/tex]

Therefore, there are 32028.8 ounces of mix in the bag.

Final answer:

To find the amount of trail mix in ounces from 0.908 kilograms, convert the weight to grams and then to ounces using the conversion of 1 oz = 28.35 g, resulting in approximately 32.012 ounces of trail mix.

Explanation:

To convert the weight of the trail mix from kilograms to ounces, we need to use the conversion factor: 1 oz is produced by a mass of 28.35 g. First, convert the kilograms to grams by multiplying by 1000, because there are 1000 grams in a kilogram. Then, once we have the weight in grams, we can convert grams to ounces using the provided conversion rate.

Here's the calculation step by step:

Convert kilograms to grams: 0.908 kg × 1000 = 908 grams.

Convert grams to ounces: 908 g ÷ 28.35 g/oz = 32.012 ounces (rounded to three decimal places).

Thus, a bag that weighs 0.908 kilograms contains approximately 32.012 ounces of trail mix.

x = 7

Step-by-step explanation:

angles 2 and 3 form a straight angle and are supplementary, that is they sum to 180°, hence

∠2 + ∠3 = 180 ← substitute values

20x - 1 +4x + 13 = 180

24x + 12 = 180 ( subtract 12 from both sides )

24x = 168 ( divide both sides by 24 )

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 3 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex], hence

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation of the perpendicular line

To find c substitute (3, 1) into the partial equation

1 = - 1 + c ⇒ c = 1 + 1 = 2

y = - [tex]\frac{1}{3}[/tex] x + 2 ← equation of perpendicular line

Answer:

Answer:

The company earned 68 billion dollars in the year 2008..

Step-by-step explanation:

This is because  the time t is the number of years since the END of 2008. The  time t = 0 at the end of 2008, so the earnings = 0^2 + 10(0) + 68 = 68 billion.

Answer:

option B

Step-by-step explanation:

A particular company's net sales is modeled by the expression (t² + 10t + 68)

Where t represents number of years since the end of year 2008.

In this expression 68 is the constant term which represents the earning of the company before 2008. or in year 2008.

The company earned 68 billion dollars in 2008.

Therefore, option B is the answer.

Answer:

g^5h^2

Step-by-step explanation:

12g^5h^4, g^5h^2

This is one way of doing it. Break down every number and every variable into a product of the simplest factors. Then see how many of each factor appear in both monomials.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

So far you see every single prime factor of each monomial.

Now I will mark the ones that are present in both. Those are the common factors.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

The greatest common factor is the product of all the factors that appear in both monomials.

GCF = g * g * g * g * g * h * h = g^5h^2

Answer:

L = 4d + 54

when d = 31 days

L = 4(31) + 54

L = 124 + 54

L = 178 miles

Step-by-step explanation:

The length of the road after 35 days of construction is 76 miles.

The length of the road after 35 days can be calculated using the given function L(d) = 41 + d, where L represents the length in miles and d represents the number of days of construction. To find the length after 35 days, we substitute d = 35 into the function.

L(35) = 41 + 35

L(35) = 76

Therefore, the length of the road after 35 days of construction is 76 miles.

x = -13

Step-by-step explanation:

Distribute:

8 - 6x + 10x - 15 = 20 - 5x

Combine like terms:

4x - 7 = 20 - 5x

Isolate Variable

-x = 13

-1(-x) = -1(13)

x = -13

Answer: [tex]x=3[/tex]

Step-by-step explanation:

You need to apply Distributive property on the left side of the equation:

[tex]2(4-3x)+5(2x-3)=20-5x\\\\8-6x+10x-15=20-5x[/tex]

Now you must add the like terms on the left side of the equation:

[tex]-7+4x=20-5x[/tex]

Add [tex]5x[/tex] to both sides:

[tex]-7+4x+5x=20-5x+5x\\\\-7+9x=20[/tex]

Add 7 to boht sides of the equation:

[tex]-7+9x+7=20+7\\\\9x=27[/tex]

And finally, divide both sides by 9:

[tex]\frac{9x}{9}=\frac{27}{9}\\\\x=3[/tex]

The y-intercept is where it crosses the y-axis. That means the x-coordinate is zero there. So this point represents how much it cost before any hours are applied. This is also known as the initial cost.

For this case we must find the point that Harold used to arrive at the following equation:

If we compare the standard equation with Harold's, we see that the slope of the line is [tex]m = 3.[/tex]

In addition, it is observed that [tex]x_ {1} = 7[/tex]and [tex]y_ {1} = 0.[/tex]
