A linear equation in slope-intercept form from two points is given by (y - y1)/(x - x1) = (y2 - y1)/(x2 - x1).
Here, y1 = 2200, x1 = 12, y2 = 3000 and x2 = 10, then
(y - 2200)/(x - 12) = (3000 - 2200)/(10 - 12)
(y - 2200)/(x - 12) = 800/-2 = -400
y - 2200 = -400(x - 12)
y = -400x + 4800 + 2200
y=-400x+7000
A quarter coin is half in value of a half-dollar coin. Therefore, two quarters makes up each half dollar coin.
Now, we know that Jessie has 14 half-dollar coins, but she needs quarters to do her laundry. Thus, if each half-dollar coin gives two quarters then 14 half-dollar coins will give quarters.
Thus, if Jessie trades all her 14 half-dollar coins for quarters, she will have 28 quarters for her laundry.
Answer:
5 = x
Step-by-step explanation:
5 divided by 2 = 2.5
12.5 divided by 2.5 = x = 5
Answer:
infinitely many solutions
Step-by-step explanation:
Because
distribute 5 into (x+10)
5x+50-25=5x+25
5x+25=5x+25
The answer is 0.
Hope this helps! :)
