Answer:

y=-4 is a function

Step-by-step explanation:

It passes the vertical line test, and each x has only one y, so it is a function.

x = -4 is NOT a function because one x has multiple y values. It does not pass the vertical line test.

Answer:

$\displaystyle 5,9708213214...\:in.$

Step-by-step explanation:

$\displaystyle {\pi}r^2 = A \\ \\ \frac{{\pi}r^2}{\pi} = \frac{112}{\pi} \hookrightarrow \sqrt{35,650707253...} = \sqrt{r^2} \\ \\ \boxed{5,9708213214... = r}$

ABCD is a parallelogram. Determine the measure of ZB.<br> A) 78°<br> B) 52°<br> C) 39°<br> D) 96°

vovikov84 [41]

$\huge\fbox{Answer ☘}$

☆ given that ,

ABCD is a parallelogram

☆ we know that ,

opposite angles of a parallelogram are equal.

Therefore ,

$\bold\blue{∠B \:= \:∠D}$

$\pink{3x = x + 52} \\ \pink{3x - x = 52 }\\\pink{ 2x = 52 }\\\pink{ x = \frac{52}{2}} \\ \\ \bold\blue{x = 26}$

therefore , ∠B = 3x = 3 ( 26° ) = 78°

$\fbox{∠B \: = \: 78°}$

thus option ( A ) is correct ~

hope helpful~
