Answer:
Step-by-step explanation:
y*1/x
y=k/x where k is the constant of variation
when y=7, x=-4
7=k/-4
k=-28
when x=5
y=-28/5
note: * is used as symbol of variation
(1,10)(-3,2)
slope = (2-10) / (-3-1) = -8/-4 = 2
y = mx + b
slope(m) = 2
(1,10)...x = 1 and y = 10
now we sub and solve for b, the y int
10 = 2(1) + b
10 = 2 + b
10 - 2 = b
8 = b
equation is : y = 2x + 8.....or 2x - y = -8
You could do 21-5 and get the answer 16
A= 16+5 = 21
So therefor, he is 16 years old now.
Answer:
Carlos is 8 , his brother is 9
Step-by-step explanation:
2x + y =25
x= 8
y= 25-16= 9
