Step-by-step explanation:
x =7y ----(1)
xy=252 ----(2)
(1) into (2):
(7y)(y) = 252
7y=15.874....
y=2.27
y value into (1)
x= 7(2.268)
x=15.87
the two numbers are 15.87 and 2.27 (Ans)
Answer:
$12,000,000
To find her commission, create a proportion.
To solve use cross multiplication.
40(x) = 100(480000)
40x = 48000000
x= 12,000,000
Find the y-intercept then model it into y = .71x + b (b is the y-intercept).
