(4x-6)+(8x+18)=180(adjacent angles are supplementary)
4x-6+8x+18=180
4x+8x-6+18=180
12x+12=180
12x=180-12
12x=168
x168/12
x=14
8x+18=y+3 (corresponding angles are equal)
8×14+18=y+3
130=y+3
-y=3-130
-y=-127
y=127
x=14, y=127
Answer:
2nd graph
Step-by-step explanation:
Given
f(x) = x² + 3x - 4
To find the zeros let f(x) = 0 , that is
x² + 3x - 4 = 0 ← in standard form
(x + 4)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
The only graph with zeros at x = - 4 and x = 1 is the 2nd graph
Answer:
x = -6
Step-by-step explanation:
-2 = 12/x
-2x = 12
x = 12/-2
x = -6
Set up a proportion. Let h = the statue height. h/statue shadow = boy height/boy shadow.
h/25 = 4.5/3.6
Cross multiply and solve for h.
