Answer:
Step-by-step explanation:
The question is 
We let 
, so the equation becomes:
Where 
By applying the quadratic formula, we arrive at:
Quadratic formula: 
Substituting yields:
We let , thus x calculates to:
and
The solutions to the equation are (rounded to 2 decimal places) and (rounded to 2 decimal places)
The telescope’s cost is $91
4.55 divided by 5% (0.05) equals 91.
The y-intercept is now 12.5, and the slope has increased to 0.5625. After the policy adjustment, an additional $5 was included, followed by multiplying the total amount by 1.25.
Let's tackle your equation step-by-step.
9x+60=10x−2
Step 1: Subtract 10x from each side.
9x+60−10x=10x−2−10x
−x+60=−2
Step 2: Subtract 60 from each side.
−x+60−60=−2−60
−x=−62
Step 3: Divide both sides by -1.
−x
/−1
=
−62
/−1
x=62
