Instead of using an = sign we use

becuase its less than or equal to 100 dollars.
The equation of the line is y=10x+7
sub in 100 for y and the inequallity sign
10x+7

100
solve so x is isolated
10x

93
x

9.3
technically the answer is 9 because you cant buy a fraction of a CD
Answer:
y=1/x-1/5
Step-by-step explanation:
tell me if u have more questions
y=-x+5
is the line so to make it perpendicular
y=1/x-1/5 i gtg
Answer:
175 cm³
Step-by-step explanation:
Volume = área * thick
Volume = 35cm² * 5cn
Volume = 175 cm³
Answer:
see explanation and attachment
Step-by-step explanation:
(1) y = -x + 2
so slope is -1 and y-intercept is (0,2)
(2) 2x - y = 7
y = 2x - 7
so slope is 2 and y-intercept is (0,-7)
