Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.
Let x represent the cost of each pound of squash and y represent the cost of each pound of eggplant.
3 pounds of squash and 2 pounds of eggplants cost $2.85. Hence:
3x + 2y = 2.85 (1)
4 pounds of squash and 5 pounds of eggplants cost $5.41. Hence:
4x + 5y = 5.41 (2)
Solving equation 1 and 2 simultaneously gives:
x = 0.49, y = 0.69
Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.

Answer:
C. F(x) = x²
Step-by-step explanation:
"Quadratic" means "second degree". The only function with an exponent of 2 is choice C.
Answer:
x = 36
Step-by-step explanation:
Answer:
A = 1
B = 2
C = below
Step-by-step explanation:
Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).
B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.
f(1.5) is negative, this means that the function is <u>below</u> the x-axis, then, C = below.
