So basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
x=
Answer: The goal was $500
======================================================
Work Shown:
x% = x/100
175% = 175/100 = 1.75
Let g be the goal, which is the amount of money the club wanted to raise
175% of goal = 175% of g = 1.75g
The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g
1.75g = 875
g = 875/1.75 ....... divide both sides by 1.75
g = 500
The club's goal was to raise $500
Note how 75% of $500 is 0.75*500 = 375
When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.
Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.

Answer:
The answer to your question is: when x = 100 days, y = 34 m³
Step-by-step explanation:
Data
Volumen = 61 m³
Loses 0.27 m³ each day
Equation y + 0.27x = 61
when x = 100, y = ?
Process, just substitute x in the equation and solve it for y
y + 0.27(100) = 61
y + 27 = 61
y = 61 - 27
y = 34 m³
It means that after ten days, the swimming pool will only have 34 m³, because 27 m³ will have evaporated.
The answer is.................
A!!!!!!!!!!!!
