Answer:
k = 2
Step-by-step explanation:
Based on the right triangle altitude theorem, thus:
4 = √(k*8)
Square both sides
4² = k*8
16 = 8k
Divide both sides by 8
16/8 = 8k/8
2 = k
k = 2
3a+7+2a and 7a+5. These expressions are not equivalent. 5a+7 does not equal 7a+5.
The standard form of a line: 
.
The point-slope form: 
We have the point (3, -1) and the slope m = -1. Substitute:
<em>add x to both sides</em>
<em>subtract 1 from both sides</em>
Answer: the X intercept mean this here

Step-by-step explanation:
Answer:
1. $66
2. 30 + 4r
Step-by-step explanation:
Let
Price of admission into the park=$30
Price of every ride in the park=$4
Number of rides =x
Total cost of going to the park= 30+4x
1. How much money would Claire have to pay in total if she goes on 9 rides
Total cost of going to the park= 30+4x
When x=9
=30+4x
= 30 + 4(9)
=30 + 36
=$66
2. How much would she have to pay if she goes on r rides?
When x=r
Total cost of going to the park= 30+4x
= 30 + 4(r)
=30 + 4r
