I believe it is 1, but i'm not completely sure.
Answer:
y=4/5x+5
Step-by-step explanation:
because this is the answer
100$ because the income you have to earn is 400$, right? If so then 100 * 4 give you 400.
The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16. ok
Answer: x= 1/4
4023/x=100/75
(4023/x)*x=(100/75)*x
4023=1.3333333333333*x
x=4023/1.3333333333333
x=3017.25
