solve for y and graph the equation with a standard window on a graphing utility. x^2 + 4y = 20 y = (simplify your answer.)
Answer
Explanation:
Step1: Isolate the term with y
Subtract $x^{2}$ from both sides of the equation $x^{2}+4y = 20$. $4y=20 - x^{2}$
Step2: Solve for y
Divide both sides of the equation $4y=20 - x^{2}$ by 4. $y=\frac{20 - x^{2}}{4}=5-\frac{1}{4}x^{2}$
Answer:
$y = 5-\frac{1}{4}x^{2}$
