Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.
w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.
Answer:
4 parts 3
Step-by-step explanation:
Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
5 because it says 11-16 which is one number before 15. dollars
The simplest way to do this is to set up equivalent fractions. So, you'd do:
=
and then solve for x.
x=52
