Answer:
625
Step-by-step explanation:
-5 x -5 = 25 and -5 x -5 = 25.

Miranda has been offered two jobs. The pay at job A would be $750 per month plus 15% of the value of the merchandise she sells. Job B offers $675 per month plus 20% of the value of the merchandise she sells. What value of merchandise must she sell in order to make more money at job B than job A? Which of the following best represents this situation?
A. 750 + 0.15x = 675 + 0.20x
B. 750 + 0.20x = 675 + 0.15x
C. 750 + 0.15x > 675 + 0.20x
D. 750 + 0.15x < 675 + 0.20x
Answer:
x - would be the total value of merchandise sold
y - would be her take home pay would be
Job A: y = 0.15x + 750
Job B: y = 0.20x + 675
We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x
0.20x + 675 > 0.15x + 750
0.20x - 0.15x > 750 - 675
0.05x > 75
x > 75/0.05
x > 1500
Miranda must sell more than $1500 worth of merchandise to have

Answer:
99.75 square feet.
Step-by-step explanation:
First we would find the area of both shapes.
rear = 12.5
distance from back and front is 9.5.
to find the area of the rectangle, you'll need to do 12.5 x 9.5
= 118.75.
Then you'd find the area of the triangles;
BH/2.
4 x 9.5. = 38. divided by 2,
= 19.
than you subtract them,
118.75 - 19 = 99.75.

You can't make a point=slope form equation.
Step-by-step explanation:
The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.
