5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92

Answer:
i think its A but not %100
Step-by-step explanation:
Old scale : 1 in. to 3 ft.
length is 9 in.....9 * 3 = 27 ft (old scale length)
width is 6 in......6 * 3 = 18 ft (old scale width)
new scale : 1 in. to 4 ft
length is 9 in.....9 * 4 = 36 ft (new scale length)
width is 6 in......6 * 4 = 24 ft (new scale width)
F(x) x^2 - 9
g(x) = 1/3 f(x)
y intercept:
f(x) = x^2 - 9
x = 0, y = - 9
g(x) = 1/ 3 f(x) = 1/3(x^2 - 9) = 1/3x^2 - 3
x = 0, y = -3
so y intercept :
f(x): -9
g(x) = -3
x intercept when y = 0
x^2 - 9 = 0
x^2 = 9
x =+3 and x = -3
g(x) = 1/3x^2 - 3 = 0
1/3x^2 = 3
x^2 = 3(3)
x^2 = 9
x = -3 and x = + 3
so g(x) also has x intercepts: -3 and 3
answer is A. first one.
f(x) x intercepts: -3 and 3
f(x): y intercept : -9
g(x) x intercepts: -3 and 3
g(x) y intercept : -3
