Is (-4, 2) a solution of 4x + 5y <-7?

Mathematics

Answer:

No

Step-by-step explanation:

To solve this problem, plug the given coordinates in for x and y.

If x = -4 and y = 2, the inequality is 4(-4) + 5(2) < -7.

Evaluating 4*-4 and 5*2, the inequality becomes -16 + 10 < -7.

Evaluating -16 + 10, the inequality becomes -6 < -7.

-6 is not less than -7, so (-4, 2) is not a solution of the inequality.

Answer:Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
