68 is the answers that it I guesss
Answer:
-5.625 in/hour
Step-by-step explanation:
−2 1/4 * 2 1/2 = -5.625 in/hour
Both lines have the same slope, which means they are parallel. They also pass through the same point
. This means they're overlapping so there is infinitely many solutions.<span />

Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Given
Slope = -3
Get the intercept c;
Substitute m = -3 and (1, -9) into y = mx+c
-9 = -3(1) + c
-9 = -3 + c
c = -9 + 3
c = -6
The equation becomes
y = -3x + (-6)
y = -3x-6
f(x) = -3x-6
The zero of f occurs at f(x) = 0
0 = -3x-6
3x = -6
x = -6/3
x = -2
Hence the zero of the function is -2
