Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10
Answer:
54
Step-by-step explanation:
What the shorthand is telling you is wherever you see an x on the right, you put in -8
f(x) = 6(1- x)
f(-8) = 6(1 - - 8)
f(-8) = 6(1+8)
f(-8) = 6*9
f(-8) = 54
