1/2 × 40 = 2x + 8
⇔ 20 = 2x + 8
⇔ 12 = 2x
⇔ x = 6
Her weekly allowance is $20
Step-by-step explanation:
Let her weekly allowance be 'a'
Given that,
She spent half of the allowance (a/2)
So,
Money left with her = (a/2)
She earned $6 by washing the car
She has $16 at the end.
So,
(a/2) + 6 = 16
(a/2) = 16 - 6
(a/2) = 10
a = 10 x 2
a = 20
So, her weekly allowance is $20
First, find the asymptotes.
When does f(x) become undefined? When the numerator is 0
0=4x-4
4=4x
x=1
Therefore, x cannot be 1, this is a horizontal asymptote.
We also know that when the degree of x in the numerator is smaller than the degree of x in the denominator, y=0.
Now that we have the horizontal asymptotes, find a third point to draw the graph.
If x=2,
f(2)=-3/4(2)-4
=-3/4
Be sure to include this points in your graph.
