You can see the slope of the line for cost per pound of cherries is greater, or in other words the line is more steep and traveling higher faster. Therefore, we know that the cost per pound of cherries is greater than that of apples because the cost increases more with each pound.
Hope this helps : )

Please confirm the question is x = (-7x^2 - 1) / (x + 4)
if that is the case, then
x * (x + 4) = -7x^2 - 1
x^2 + 4x = -7x^2 -1
8x^2 + 4x + 1 = 0
which does not have any real solution
Edit - much easier question to evaluate the expression (x^2 -1) / (x + 4) when x=-7
(-7^2 - 1) / (-7 + 4)
= (49 -1 ) / -3
= 48 / -3
= -16
Answer:
n = nickels, q = quarters
Equation 1: n+q=30
Equation 2: 0.05n+0.25q = 3.30
Step-by-step explanation:
From equation 1, n = 30-q
Substitute in Equation 2:
0.05(30-q) + 0.25q = 3.30
1.5 - 0.05q + 0.25q = 3.30
0.2q = 1.8
q = 9
Substitute in new equation:
n = 30-9
n = 21
It is important to note a nickel is worth 5 cents and a quarter is 25 cents. This helps us build the equations.
