The feasible region is shown in the picture above. The horizontal axis is the X axis.
If you now draw a family of lines parallel to through the region, increasing $C$, that is, the X-intercept, we will have the maximum value of $C$ when the line passes through the endpoint $(-2,6)$ .
Hence, $C=5(-2)+4(6)=14$

Answer:
$165 is the total cost of the first year of Keecia’s gym membership
Step-by-step explanation:
formula for direct proportion : y = kx
x = 50
y = 75
50 = k * 75
k = 75/50
k = 3/2x
substitute y = 60
60 = 3/2x
x = 3/2 * 60
x = 90
$90 + $75 = $165
Answer:
10 boards
Step-by-step explanation:
In this case we can reverse the calculation or whatever you call it
<em>X</em>(how many boards)x3,75 (length per board)= 36 (total length for the table)
now we reverse it by writing 36/3,75 and we get 9,6.
but we need a whole board/number. which means instead of having 9 and 0.6 boards, we add an entire board instead. 9+1=10
