Answer:
2y=-14
Step-by-step explanation:
If y=-7 and you multiply y by 2, you do the same thing to both sides and get -7 × 2 = -14
<span>2[4x-5(2x-1)]
=</span><span>2[4x- 10x + 5]
= 2(-6x + 5)
= -12x + 10</span>
<u>x = 0</u>
y = 26 - 4x + 2
y = 26 - 4(0) + 2
y = 26 - 0 + 2
y = 26 + 2
y = 28
(x, y) = (0, 28)
-----------------------------------------------------------------------------------------------
<u>x = 3</u>
y = 26 - 4x + 2
y = 26 - 4(3) + 2
y = 26 - 12 + 2
y = 14 + 2
y = 12
(x, y) = (3, 12)
-----------------------------------------------------------------------------------------------
<u>x = 6</u>
y = 26 - 4x + 2
y = 26 - 4(6) + 2
y = 26 - 24 + 2
y = 2 + 2
y = 4
(x, y) = (6, 4)
-----------------------------------------------------------------------------------------------
Domain (Input): {0, 3, 6}
Range (Output): {28, 12, 4}
{(0, 28), (3, 12), (6, 4)}
ABC is a isosceles triangle
AC = BC
so
<A = <B
2x - 20 = x + 8. solve for x
subtract x to both sides
2x - 20 - x = x + 8 - x
x - 20 = 8
add 20 to both sides
x - 20 + 20 = 8 + 20
simplify
x = 28
<A = <B = 28 + 8 = 36
<C = 180 - 2(36)
<C = 180 - 72
<C = 108
Answer
B. 108 degrees
