Answer:
C. ⅐
Step-by-step explanation:
Recall: the slope of a line that is perpendicular to another is the negative reciprocal of the slope of the other line that it is perpendicular to.
Thus:
Slope of red line = -7
The green line that is perpendicular to the red line will have a slope that is the negative reciprocal of -7.
Negative reciprocal of -7 = ⅐
The slope of the green line is therefore ⅐
the values of x are -7/5 and -7/8 .
No solution.
Explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x.
(a)3-2=1 (b) 4-3=1 (c) 12-1-1=10

18/6 = 3
24/8 = 3
21/x = 3
21/3 = 7
x = 7
