For A, you wanna look at $350 and $750 and find out how much her pay increased from 2010 to 2014.
For B, you want to create an equation (math problem) <span>to represent the fees that Sarah charges each year that would be reliant to your answer for part A. Hope this helps!

Answer:
d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.
Step-by-step explanation:
d=vt
v=14m/s
t=18s
d= vt, (14m/s)(18s)
d=252m
Let 2x – y = 3 ——— equation 1
Let x + 5y = 14 ——— equation 2
Making x the subject in eqn 1, = x = y + 3 / 2 ——— eqn 3
• Put eqn 3 in eqn 2
(y + 3 / 2) + 5y = 14
6y = 14 – 3/2
6y = 25/2
y = 25/12
• put y = 25/12 in eqn 3
x = (25/12 + 3/2)
x = 43/12
Answer:
-1
Step-by-step explanation:
Slope formula: (y₂ - y₁) / (x₂ - x₁)
= (2 - 1) / (1 - 2)
= -1
