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.
(-5,5)(3,-5)
slope = (y2 - y1) / (x2 - x1)
slope = (-5-5) / (3 - (-5)
slope = -10/(3 + 5)
slope = -10/8 = - 5/4 <== ur slope
X^2 + y^2 - 2x + 2y - 1 = 0
(x^2 - 2x) + (y^2 + 2y) - 1 = 0
(x^2 - 2x + 1) + (y^2 + 2y + 1) - 1 - 1 - 1 = 0
(x - 1)^2 + (y + 1)^2 - 3 = 0
(x - 1)^2 + (y + 1)^2 = 3
Answer: the answer is 2/3
Step-by-step explanation: hope this helps
Answer:
Kaely gets 1,680 and Bro gets 1,120
Step-by-step explanation:
First you need to find how may bucks you will receive with 1$
2,800/25
which equals 112
Then multiply 112 by how much Kaely paid and how much Bro paid. Then you have your answer.
