K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
Answer: The scale of dilation is 2.5

What is the value of x in the equation 3x – y = 18, when y = 27?
atroni [7]
<span>3x – y = 18 

We start by plugging in 27 for y. The goal is to isolate x by itself to solve for x.

3x - 27 = 18

Then we add 27 to both sides of the equation

3x = 45

Lastly, we divide both sides by 3 to finally isolate x by itself and solve.

x = 15</span>

What is the value of the sum? - 3/8+ 5/10 <br> -11/16<br> -1/16<br> 1/16<br> 1/4<br> -1/4
mafiozo [28]
First, you must convert the decimals to have the same denominator.

Find the least common multiple of both fractions' denominators:

Multiples of 8: {8,16,24,32,40}
Multiples of 10: {10,20,30,40}

The least common multiple of 8 and 10 is 40.

Multiply the fractions by a number that will make their denominator 40:

- \frac{3}{8} \times  \frac{5}{5} = - \frac{15}{40}
\frac{5}{10} \times \frac{4}{4} = \frac{20}{40}

Now you can add these fractions together:

-\frac{15}{40} + \frac{20}{40} = \frac{5}{40}

Simplify this fraction:

\frac{5}{40} \div \frac{5}{5} = \frac{1}{8}

The answer should be 1/8.

Answer:

B. x^2

Step-by-step explanation:

If m = x/y and

n = 1/xy

then

m/n = (x/y)/(1/xy)

You can simplify this complex fraction (fraction over a fraction) with the method Keep-Change-Flip. It works!

KEEP x/y

CHANGE ÷ to ×

FLIP 1/xy over to be xy/1

See image.

x/y • xy/1

= x^2

DerKrebs [107]

Answer:

x = 9, ∠ 1 = ∠ 2 = 66°

Step-by-step explanation:

If r and s are parallel then

∠ 1 = ∠ 2 ( corresponding angles ) , then

84 - 2x = 93 - 3x ( add 3x to both sides )

84 + x = 93 ( subtract 84 from both sides )

x = 9

Then

∠ 1 = 84 - 2x = 84 - 2(9) = 84 - 18 = 66°

∠ 2 = 93 - 3x = 93 - 3(9) = 93 - 27 = 66°
