Water boils at different elevations. The boiling temperature of water is 212° F at sea level (0 feet) but drops about 1.72°F for every 1,000 feet of elevation. Write a formula for the boiling at a given elevation. Then solve the formula for the elevation when the boiling point of the boiling point for water is 190°F.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

16.80 times .20= 3.36

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
