Y2=(4*10^7)(7*10^7) rounded to the nearest million

Solve for y:

y^2 = 2.8×10^15

Take the square root of both sides:

y = 5.2915×10^7 or y = -5.2915×10^7

or y= 5,2915,000 y = -5,2915,000

Step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
