First step: x= ± √ 121
Second step and correct answer: x= ± 11
Because: x^2 = x= ± √
The center-radius form<span> of the </span>circle<span> equation is in the format (x – h)</span>2<span> + (y – k)</span>2<span> = r</span>2<span>, with the center being at the point (h, k) and the radius being "r". Therefore, the center is located at point (1, -3) and is located in the fourth quadrant, last option. Hope this answers the question.</span>
Step-by-step explanation:
160 miles = 20 gallons
400 miles = x gallons
160 × x = 20 × 400
x = 8, 000/160
x = 50 gallons
Answer:
