Suppose a line passes through (a, –11) and (7, 13), and is parallel to the line y = 2x + 8. What is the value of a? Write the equation of the line.

Answer:

40

Step-by-step explanation:

The answer should be 40 assuming that there are positive real numbers.

You simplify the radical into a product with known factors

sorry If that doesnt make sense lol

Answer:

21

Step-by-step explanation:

Answer: Our required answer is 11(2c+3d)

Step-by-step explanation:

Since we have given that

22c + 33d.

We have to use "Distributive property" to factor out the greatest common factor.

Since we know that 11 is the greatest common factor of 22 and 33.

So, it becomes,11(2c+3d)

Hence, our required answer is 11(2c+3d)

Answer:

1/2

Step-by-step explanation:

Given that:

3/4 of pizza has pepperoni

2/3 of the pizza with pepperoni has green pepper ;

The fraction of the whole pizza that has both pepperoni and green pepper ;

Fraction with pepperoni = 3/4

Fraction of whole with green pepper and pepperoni : 2/3 of 3/4 = 2/3 * 3/4 = (2*3) / (3*4) = 6/12 = 1/2

Answer:

# 1,3 and 6

Step-by-step explanation:

Answer:

C = 3n

Step-by-step explanation:

Given that,

The fabric is $3 times the number of yards of fabric n.

We need to find an equation that gives the total cost c of n yards of fabric.

It means, the total cost of n yards of fabric is given by :

C = 3n

Where

n is yards of fabric.

Answer:

[tex]\frac{3x-6}{x(x-3)}[/tex]

Step-by-step explanation:

We require the denominators of the fractions to be common.

Multiply numerator/denominator of first fraction by x - 3

Multiply numerator/denominator of second fraction by x

Then

= [tex]\frac{2(x-3)}{x(x-3)}[/tex] + [tex]\frac{x}{x(x-3)}[/tex] ( simplify numerators, leaving the common denominator

= [tex]\frac{2x-6+x}{x(x-3)}[/tex]

= [tex]\frac{3x-6}{x(x-3)\\}[/tex]

Answer:

its 34

Step-by-step explanation:

its half of the center angles

Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

[tex] \large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }[/tex]

First, we simplify 5² and 4²

[tex] \large{ \frac{ {x}^{2} }{25} = 16}[/tex]

Multiply the whole equation by 25 to get rid of the denominator.

[tex] \large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}[/tex]

Square both sides and solve the equation.

[tex] \large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}[/tex]

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

[tex] \large{x = \pm{20}}[/tex]

Well you said the Coordinates of F  (7,-2) rotated 90 degrees

Answer:

You have to multiply 24 and 8, which will give you 192. For a triangle, you always must divide by two, and doing so on this equation will give you 96. Like everything involving area, or something with a measurement, you must use the proper measurement unit, in this case that would be feet. In all, the answer is 96 feet for the overall area of the triangle. The formula for this process is A=[tex]\frac{hb}{2}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

This is how you find the area of a triangle. First, you must use the formula

A= 1/2 b·h. Replace the given informations. (the steps will be on a drawing so you will be able to understand how to solve.)

Answer:

1/2

Step-by-step explanation:

you could get 2 or 4 or 6

Answer:

6

Step-by-step explanation:

We know that the two quads are of similar and the ratio is 1:2, thus

AB/RS = 1/2

3/x = 1/2

x = 6

Answer:B.rotation

Step-by-step explanation:

Answer:

Step-by-step explanation:

Surface Area = 4πr²

Volume = 4/3 πr³

VOLUME

4/3 *6³ *π=

4/3 *216π

216/3 = 72*4 = 288π

SURFACE AREA

4*π*6²=

4*36π=

144π

Overall the answer should be C.
