The answer is b.6, you set up a proportion of the corresponding sides in both triangles...12/9=8/x solve for x and get 6.
Answer:
B)Only one graph intersects the y-axis above y=0
Step-by-step explanation:
Both functions are in y=mx+b. The y-intercept is b.
f(x) has the y-intercept 3. It intersects above y=0.
g(x) has the y-intercept -4. It intersects below y=0.
This means B is correct.
The answer is
5q/2 or q×5/2
You have to distribute the parentheses first. Since there is a negative sign in front of the parentheses, it counts as a negative 1. After you distribute you should get: -5+6x=20x+12, but that is not your final answer. After you add like terms: 17x=-17. Divide 17 on both sides: x=-1. X=-1 is your final answer.
