(5x+1) If X=3 then 5(3)+1=16
(2×2y) if Y=2 then 2×(2)2=8
16÷8=2
Answer: second option -300+150+(-50)
Explanation:
She going down, the value is negative. When going up, the value is positive. So when the swimmer swims down 300 feet, the value is negative. Then he goes up 150 ft, which makes the value positive. Finally, he swims down 50 ft, so the valued is negative.
Answer: A
Step-by-step explanation:
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.
If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.
So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
