Answer: 23
Step-by-step explanation:
Answer:
8
Jacks age: x-14
Jack's brothers age: x
In 6 years time:
Jack's age: x-8
Jack's brother's age: x + 6
Given that:
x+6 = 2(x-8)
Simplify:
x+6 = 2x-16
x+22 = 2x
2x = x+22
x = 22
we mentioned earlier that Jack's brother's age was x. but Jack's age was x-14.
So, Jack's age: 22-14 = 8
Hope this helps.
Good Luck
f(x)= 2x^2-4x
y+1=5/2(x+2)
m=(y2-y1)/(x2-x1)
m=(-6-(-1))/(-4-(-2))
m=(-6+1)/(-4+2)
m=-5/-2
m=5/2
y-y1=m(x-x1)
y-(-1)=5/2(x-(-2))
the slope is 150 a day.
Hope this helps!
