Answer:
$7; Cost of a box of apples (x)
$13; Cost of a box of oranges (y)
Step-by-step explanation:
Matt: 3x + 14y = 203 3(-y + 20) + 14y = 203 3x + 14(13) = 203
Ming: 11x + 11y = 220 -3y + 60 + 14y = 203 3x + 182 = 203
11x = -11 11y = 143 3x = 21
x = -y + 20 y = 13 x = 7
When the graph is constant, you have to look for when it draws a straight line.
Look at the x axis, since it asks for the x value.
Your answer is correct! When x = 0, to x = 3, the function is constant.

Answer:
(2,0) and (2,-2)
Step-by-step explanation:
y+3<2x
(2,0) is solution because 0+3<2*2, 3<4 and
(2,-2) because - 2+3<2*2, 1<4
<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
