If the question is:
"<span>Find two positive numbers whose difference is 28 and whose product is 3900</span>"
If the larger number is x, then
x-3900/x=28
multiply by x and transpose
x^2-28x-3900=0
Factor
(x+78)(x-50)=0
Using the zero product property,
x=-78 or x=50, ie. x=50, y=-78
NOTE: if question requires both numbers be positive, there is no solution.
Answer:
x=8=2=3
Step-by-step explanation:
X1= -3 -root 29 /2
x2=-3+ root 29 /2
Well if she’s doing a two month membership she will have to pay $215
This is because if you follow the y=mx+b form you get b=175 Bc that represents the cost for application and the m=20 Bc it’s 20 dollars per month. This then means the 2 is the x because it’s that’s the value/the months. So then y=20(2)+175, 20(2)=40, 40+175=215, y=$215
