Answer:
(0, 9)
Step-by-step explanation:
The y-intercept is the point when x = 0. By looking at the graph, when x = 0, y = 9. Therefore, the y-intercept of the line is (0, 9).
Answer:
x = 9/2
Step-by-step explanation:
6x - 8 = 4(x + 2) - 7
Distribute on the right side.
6x - 8 = 4x + 8 - 7
Combine like terms on the right side.
6x - 8 = 4x + 1
Add 8 to both sides. Subtract 4x from both sides.
2x = 9
Divide both sides by 2.
x = 9/2
Answer:
a=9
Explanation:
The triangle is a 45-45-90 triangle, so the sides have a 1-1-root 2 ratio. So, if 9 root 2 is to root 2, then find a to 1. You can solve this by setting up the ratio and solving for a:
a/1=9root2/root2
a/1=9
a=9
