Answer:

C. Both (1, 11) and (-1, -5)

Step-by-step explanation:

The missing options are:

A. Only (1, 11)

B. Only (-1, -5)

C. Both (1, 11) and (-1, -5)

D. Neither

To check if an ordered pair is a solution of an equation, replace one variable into the equation an calculate the other one.

Replacing x = 1, we get:

y = 8(1) + 3

y = 11

then (1, 11) is a solution

Replacing x = -1, we get:

y = 8(-1) + 3

y = -5

then (-1, -5) is a solution

What is the length of z? (Round to the nearest tenth)

navik [9.2K]

Answer:

z = 10.8

Step-by-step explanation:

$9^{2} + 6^{2} = c^{2}$

81 + 36 = $c^{2}$

117 = $c^{2}$

c = $\sqrt{117}$

c = 10.8

c = z

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Polygon X is similar to polygon.

And Polygon X is three times the size of polygon Y.

So, it becomes,

$\dfrac{\text{Perimeter of polygon X}}{\text{Perimeter of polygon Y}}=\dfrac{3}{1}\\\\\dfrac{81}{x}=\dfrac{3}{1}\\\\x=\dfrac{81}{3}\\\\x=27$

Hence, perimeter of polygon Y is 27.

Therefore, Option 'C' is correct.
