Answer:

Step-by-step explanation:
In order for two lines to be parallel, they must have the same slope. So, we know that the slope of the other line is 4/5.
We're given an ordered pair, so we can solve for
in the (slope-intercept form) equation 


The answer is HC, HT, HH, CC, CT, CH, TC, TT, TH
2y-7x=-9
4x+6=y
2(4x+6)-7x=-9
8x-7x=-12-9
x=-21
y=4(-21)+6
y=-84+6
y=-78
Answer:
3840 ft³
Step-by-step explanation:
Volume of a pyramid = 1/3( base area x height)
Base area = area of a square
area of square = length²
= 24² = 576
volume = 1/3(576 x 20) = increases as the price falls
