Part 1
Let:
y be the total cost
x be the number of tickets
a be fair admission
Since the fair charges $1.25 per ticket, the equation of the line would look like:
y = 1.25x + a
Since Johnny spent $43.75 and bought 25 tickets, we find a by replacing y with 43.75 and x with 25:
43.75 = 1.25×25 + a
Now solve for a
43.75 = 31.25 + a
43.75 - 31.25 = a
a = 12.50
Going back to the first equation:
y = 1.25x + 12.50
Part 2:
a) Let (9,8) be (x1,y1) and (4,-12) be (x2,y2)
The formula for slope is:

b) For the point-slope equation, I'll use (9,8)
Using the formula:

c) For the slope-intercept form, we solve for y in the point-slope formula:
Well, i am not sure if i am right, but i tried.
The prime numbers have to be consecutive, (meaning in order from least to greatest), so you find 2 prime numbers on a list, and the only two are 31 and 37 so multiply those and you should get 1147
Answer:
8 inches
Step-by-step explanation:
V= Volume
A= Base
H= Height
<em>Formula: H= V÷A</em>
336in÷ 42in²= 8in
Answer:
I'm assuming you mean a compression of factor 6
In that case, it will be h = 1/6x
21
is what I got on my calculator
