Answer: 6x+18

Step-by-step explanation: Because of the Distributive property, you would multiply the 6 by the’x’ and 3, as they are in the parenthesis.

The distributive property is the ability of one operation to "distribute" over another operation contained inside a set of parenthesis. So, all we (you) need to do is "distribute" the 6 to the x and 3. Observe.

6(x + 3) =

6x + 18 is the rewritten equation using the distributive property.

Answer:

B.  9/4 <x <= 4

Step-by-step explanation:

5x - 19 <= 1

5x <= 20

 x <= 4

-4x + 3 < - 6

-4x < - 9

  x > 9/4

Answer

9/4 <x <= 4

Answer:

x ≤ 4

Step-by-step explanation:

1. 5x - 19 ≤ 1

Add: 5x ≤ 20

Divide: x ≤ 4

2. -4x + 3 > -6

Subtract: -4x > -9

Divide: x < ⁹/₄

3. Or means the union of the two sets, or all values that are in either set.

x ≤ 4 ∪ x < ⁹/₄ is x ≤ 4, since they both inequality signs point left, and 4 is larger than ⁹/₄, so x ≤ 4 also includes x < ⁹/₄.

I see here that x ≤ 4 is not one of the options. I'm not sure what to do then.

Answer: 3/4 or Choice A

The answer for AB is 5.

To find this answer, you would use Pythagorean Theorem. The equation would be a² + 12² = 13². First, square 12 and 13, to get the equation to say a² + 144 = 169. Next, subtract 144 from both sides. This leaves a² = 25. Finally, square root  both sides to a = 5. Thus meaning 5 is the answer.

Answer:

Step-by-step explanation:

Answer:

Length =12

Width= 10

Step-by-step explanation:

The difference between two consecutive integers is 2.

Thus the difference between the length and the width of the rectangle also differ by 2.

width- x

length- x+2

AREA=L×W

120=x(x+2)

x²+2x-120=0

Factorizing:

x² - 10x + 12x - 120=0

x(x-10) + 12( x-10)=0

(x-10)(x+12)=0

either x-10=0 or x+12=0

x=10 0r -12

We consider positive roots only. thus x=10

width = 10

length = 10+2 =12

Answer:

16 quarters 2 dimes

Step-by-step explanation:

16 quarters is 4 dollars

2 dimes is 20 cents

Step-by-step explanation:

If D is number of dimes and Q is number of quarters:

D + Q = 21

10D + 25Q = 420

Solve the system of equations through either substitution or elimination.

10D + 25(21 - D) = 420

10D + 525 - 25D = 420

105 = 15D

D = 7

Q = 14

There are 7 dimes and 14 quarters.

Answer:

B.

Step-by-step explanation:

Let's find g(f(x)) for each choice for fun and so you can have more examples:

A) f(x)=3x and g(x)=sqrt(x)+1

so g(f(x))=g(3x)=sqrt(3x)+1

So definitely not this choice

B) f(x)=x+1 and g(x)=sqrt(3x)

so g(f(x))=g(x+1)=sqrt(3(x+1))

So this one works! :)

C) f(x)=sqrt(x)+1 and g(x)=3x

so g(f(x))=g(sqrt(x)+1)=3(sqrt(x)+1)

Not this one!

D) f(x)=sqrt(3x) and g(x)=1

g(f(x))=g(sqrt(3x))=1

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{4-x}{8}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = - 8x + 4 ( add 8x to both sides )

8x + y = 4 ( subtract y from both sides )

8x = 4 - y ( divide both sides by 8 )

x = [tex]\frac{4-y}{8}[/tex]

Change y back into terms of x

[tex]f^{-1}[/tex](x) = [tex]\frac{4-x}{8}[/tex]

Answer:

C.) 5.1

Step-by-step explanation:

First, solve for J's angle of degrees

180 - (120 + 40) = 20

Second, fill in all the information that you know in the equation

sin(20) / 2 and sin(120) / k

Third, cross multiply

k x sin(20) = 2 x sin(120)

Fourth, solve for k

k x sin(20) / sin(20) = [2 x sin(120)] / sin(20)

k = [2 x sin(120)] / sin(20)

k = 5.0641777.....

Fifth, round to the nearest tenth

k = 5.1

The value of digit 1 in the number 13 is 10 because it is located in the 'tens' place.

The value of the digit 1 in the number 13 corresponds to its place value in the number. In the number 13, 1 is in the 'tens' place, thus its value is 10. Place value is determined by the position of a digit in a number. It shows the mathematical worth of each digit at their respective places. Zeroes play a significant role in deciding the place value of digits in a number, acting as placeholders that help identify decimal points.

Answer:

420

Step-by-step explanation:

Each of the 7 appetizers can be paired with one of 10 entrees, and each entree can be paired with one of 6 desserts.  So the number of combinations is:

7 × 10 × 6 = 420

By combination property, there are a total of 420 different lunch specials that are possible.

The combination property is defined as the selection of items from a set that has distinct members, such that the order of selection does not matter.

It is given that a restaurant offers a lunch special in which a customer can select from one of the 7 appetizers, one of the 10 entrees, and one of the 6 desserts.

Thus, there are 3 different items which quantities are also mentioned. '

Thus by combination property, the total number of lunch specials that are possible -

7 * 10 * 6 = 420 .

Therefore, by combination property, there are a total of 420 different lunch specials that are possible.

Answer: y=3x+8

Step-by-step explanation:

The slope will be the same as the original equation, so 3. And to make the line go the points (0,8), you can plug in 0 into the original equation to find what needs to change. Hope this helps!

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

If lines are parallel then they have the same slope (m)

This means that the slope of the line will be 3

y = 3x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(0, 8)

8 = 3(0) + b

8 = 0 + b

8 = b

y = 3x + 8

For this case we have by definition, that each of the four internal angles of a square measure 90 degrees.

If we draw the diagonals of the square then the angles are divided by two, that is:

[tex]\frac {90} {2} = 45[/tex]

Thus, angle 3 measures 45 degrees.

[tex]A3 = 45[/tex]

By definition, the sum of the internal angles of a triangle is 180 degrees.

So:

[tex]A2 + A3 + 90 = 180\\A2 = 180-90-A3\\A2 = 180-90-45\\A2 = 45[/tex]

Thus, angle 2 measures 45 degrees.

Notice that for each unit increase in x, y increases by 1 unit.  Thus, the parent function is y = x.

Answer:

f(x)=x

We are given with a table, Lets look at the value of x  and y

The value of y is constantly increasing and the value of x is also increasing constantly. So it is a table for a linear equation.

the value of x  and y are same, so the equation of the line is

corresponding              15                              3

corresponding               x                               6

so you are trying to solve 15/x=3/6

cross multiply 6(15)=3(x)

last step divide both sides by 3 giving x=30 ft

If the triangles are similar, value of x in the drawings is Option(B) 30 ft.

Similar triangles are triangles that have the same shape, but their sizes may vary. If two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

The given two triangles are similar .

In the diagram, it is mentioned that one side is 3 and its corresponding other side of the similar triangle is 15 .

Thus the proportion is 15/3 = 5

Therefore if the other side of the same triangle is 6 then its corresponding other side of the similar triangle will be 6*5 = 30

Thus x = 30 ft.

Therefore, if the triangles are similar, value of x in the drawings is Option(B) 30 ft.

Answer: [tex]arc\ length=6.3\ ft[/tex]

Answer:

the ordered pair is (2,-1)

Step-by-step explanation:

We need to solve the system of equations using elimination method

12x - y = 25     eq(1)

9x + y = 17      eq(2)

Adding eq(1) and eq(2)

12x - y = 25

9x + y = 17

___________

21x = 42

x = 42/21

x= 2

Now, putting value of x in equation 1

12x - y = 25

12(2) -y = 25

24 -y = 25

Adding -24 on both sides

24 -y-24 = 25-24

-y = 25-24

-y = 1

Multiply both sides by -1

y = -1

the value of x = 2 and y = -1

So, the ordered pair is (2,-1)

Answer:

The solution is: (2, -1)

Step-by-step explanation:

I have the following system of equations

[tex]12x - y = 25[/tex]

[tex]9x + y =17[/tex]

Note that if we add both equations, the variable y is "eliminated".

So add the first equation to the second and solve for the variable x

[tex]12x - y = 25[/tex]

[tex]9x + y =17[/tex]

----------------------------------

[tex]21x=42[/tex]

[tex]x=\frac{42}{21}\\\\x=2[/tex]

Now substitute the value of x in any of the two equations and solve for the variable y

[tex]9(2) + y =17[/tex]

[tex]18 + y =17[/tex]

[tex]y =17-18[/tex]

[tex]y =-1[/tex]

The solution is: (2, -1)

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept (0, b)

We have the slope m = -3/2 and the y-intercept b = 3.

Substitute:

y = -3/2x + 3

The x-intercept is for y = 0. Substitute:

0 = -3/2x + 3           add 3/2x to both sides

3/2x = 3     multiply both sides by 2

3x = 6           divide both sides by 3

x = 2
