You need to use a diagram at least if your a beginner
Let us say
The Height from which the ball was first dropped as H0 = 248 feet
The Height reached by the ball after second bounce is H1
The Height reached by the ball after second bounce is H2 = 62 feet
Given , Height the ball reaches after bounce is a fraction of the height the ball reached in the previous bounce
The Height reached by the ball after second bounce = H2 = X of H1
==> 62 = X * H1 ...................Equation 1
The Height reached by the ball after first bounce = H1 = X of H0
==> H1 = X * 248 ...................Equation 2
Substituting value of H1 from Equation 2 to Equation 1
62 = X * H1 = X * X * 248
X^2 = 62/248 = 31/124 = 1/4
X = 1/2
Answer is A. 1/2

Answer: C
4x - y = 6
2x - y/2 = 4 /multiply both sides by 2 to get rid of the fraction
4x - y = 6
4x - y = 8
This system has no solution because it contradicts itself.
Answer:
The y intercept is -1
Step-by-step explanation:
The y intercept (when written in slope-intercept form) is always the constant at the end of the equation. In this case, that constant is -1.
