Answer:
Marissa has $80
Step-by-step explanation:
are you sure its asking for Marissas money or Franks money? but its fine if its Marissa too
Christina: 100
Marissa: 20 less than her
So 100-20=80
And Marissa has $80
Just in case, heres how to find Franks money:
100-20=2x
subtract 20 from both sides
80=2x
divide by 2
40=x
And Frank has $40
Move it it up 4 and then find your x intercepts.
Find the x intercepts.
<u>Move the 4 over to the right</u>
<u>Divide out the - </u>
<u>Take the square root of each side</u>
Our x intercepts are at (-2,0) (2,0)
x>-2
3+4x>-5
4x>-5-3
4x>-8
the answer is x>-2
5.164×10^-5
