Answer:

b. y=12x+32, c. y-8=12(x+2)

Step-by-step explanation:

point -slope form equation

(y-y1) = m(x-x1)

(y - 8) = 12(x + 2) point slope form

y - 8 = 12x +24

y = 12x + 32 slope intercept form

An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest cir

Serhud [2]

Answer:

The artist used $8.6\ in$ more of silver wire

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

we know that

The Perimeter of the square is equal to

$P=4a$

where

a is the length side of the square

$P=40\ in$

$40=4a$

$a=10\ in$

Each side of the square has a length of 10 in

step 2

Find the circumference of the circle

The diameter of the circle is equal to the length of the side of the square

The circumference is equal to

$C=\pi D$

we have

$D=10\ in$

substitute

$C=(3.14)(10)=31.4\ in$

step 3

Find the difference

$40\ in-31.4\ in=8.6\ in$

Determine the value of x in the figure. answers: A) x = 90 B) x = 40 C) x = 45 D) x = 135

Answer:

Please mark be brainliest and I hoped this helped!

x = 45°

Step-by-step explanation:

Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
