Answer:
???????
Step-by-step explanation:
I think it does pass through (3, -6) and the slope is 2, -3 based on the information I was given.
Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3

Answer:
88 square inches
Step-by-step explanation:
if the entire square was shaded it would be 14 x 12 (as best as i can see)
the "cut out" or white part of the square is 8 x 10
Entire squre - cutout white part
14 x 12 - 8 x 10
168 - 80
88 sq in
Answer:
0.25 per gallon
slope: 0.25
Step-by-step explanation:
the train travels 25 miles per 100 gallons
this simplifies into 0.25 per 1 gallon
slope is y/x
y/x = 25/100 = 0.25
