Answer:
the solutions are 13 and -13
Step-by-step explanation:
13 x 13= 169
-13 x -13=169
a negative times a negative equals a positive
With the formula: m=(y1-y2)/(x1-x2) you can sub in the values to get the slope (m).
m=(4-2)/(2-(-3))
= 2/5
Therefore the slope is 2/5.
The answer is D. 63. You have to set up a proportion as shwon in the image.
Answer:
- 320 +0.05s ≥ 600
- sales ≥ $5600
Step-by-step explanation:
For sales of 's', Alan's earnings will be ...
320 +0.05s
He wants that to be at least 600, so the inequality is ...
320 +0.05s ≥ 600
__
Its solution is found by subtracting 320 and dividing by 0.05.
0.05s ≥ 280
s ≥ 5600
Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.
