Answer:
1.27
Step-by-step explanation:
In Centimeter It's 127 Just Put A Decimal! :)
Hello:<span>
the equation is : y = ax+b
the slope is a
</span><span>3x-4y=5.....
</span><span>4y = 3x-5
y = (3/4)x -5/4
the slope is (3/4)
</span><span>

When we are looking for the mid point, we are looking for a point that is an equal distance from point R and S.
Since the x value has no change, we can ignore it.
For the y value, we want to simply find the difference between the points (7 - 1 = 6) and then divide that value by 2 (6 / 2 = 3).
You can then subtract that value from the higher Y value, where you will get 4.
Leaving you with the coordinate (3,4)
Hope this helped. There are definitely more ways you could find to solve this, but this works best for this problem.
<span>SALES: 5x² + 2x – 80
</span>- COST: 5x² – x + 100
= ------------------
PROFIT: 0x²+3x-180
(+3x because we subtracted a negative (-x), which is called adding, similarly taking away 100 from negative 80 is -180.)
Checking:
5x² + 2x – 80
5(500)²+2(500)-80 = 1,250,920
5x² – x + 100
5(500)² – (500) + 100= 1,249,600
Profit = 1,250,920 - 1,249,600 = 1,320
0(500)²+3(500)-180 = 1,320 YAY! {:-)
Double Checking:
5x² + 2x – 80
5(5000)²+2(5000)-80 = 125,009,920
5x² – x + 100
5(5000)² – (5000) + 100= 124,995,100
Profit = 125,009,920 - 124,995,100 = 14,820
0(5000)²+3(5000)-180 = <span>14,820</span> YAY! {:-)
