Answer:
x = -2
Step-by-step explanation:
7(2 - x) = 28
Distribute
14 -7x = 28
Subtract 14 from each side
14-7x-14 = 28-14
-7x = 14
Divide each side by -7
-7x/-7 = 14/-7
x = -2
Answer:
Step-by-step explanation:
2x + 2 + 3x + 6 = 23
5x + 8 = 23
5x = 15
x = 3
3(3) + 6 = 9 + 6 = 15 = BC
G(x) = 3x - 5
let g(x) = y
y = 3x - 5
y + 5 = 3x
3x = y + 5
x = (y + 5)/3
From y = g(x), x = g⁻¹(y)
<span>x = (y + 5)/3
</span>
g⁻¹(y) = <span>(y + 5)/3</span>
g⁻¹(x) = <span>(x + 5)/3</span>
Unknown. C is the hypotenuse, but this problem is solvable.
Answer:
Answer B and C
Step-by-step explanation:
Z is the center of the circle passing through H,G,J:
HZ=85=ZG=ZJ ==> ZJ=85 : B is true
HK=KG=136/2=68: C is true.
