Answer:
h
8
Step-by-step explanation:
h-(-2)
10=h+2
10
subtract 2 on both sides to get h
8
4x-3+7x+1
Ones with a variable: 4 & 7
Only whole number: -3 & 1
The answer is option two: -3 and 1; 4x and 7x
Answer:
seconds
Step-by-step explanation:
When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:

Plugging this into the quadratic equation, you get:

Since the time must be positive, it takes the ball
seconds to hit the ground, or around 3.828. Hope this helps!
Answer:
corresponding angles- 4 and 8, 3 and 7, 1 and 5, 2 and 6
same side interior angles- 2 and 5, 3 and 8
alternate interior angles- 3 and 5, 2 and 8
alternate exterior angles- 1 and 7, 4 and 6
Step-by-step explanation:
5/38 is 0.13 because you have to divide them
