Is the ordered pair (-2,9) as a solution of the equation y=x-7

1 answer:

3 0

Hi there! To answer that question, no. -2 is the x value and 9 is the y value. When you plug them in, -2 -7 is -9, not positive 9. So no. The order pair (-2, 9) is not a solution to the equation of y = x - 7.

Let n = the number. A number exceeds 45 inequality

This translates to "a number" is greater than 45. All you have to do now is translate these words into an algebraic statement. Basically, you replace "a number" with the variable which it is defined for, and you use the "greater than" symbol to show that the variable is greater than the value of 45.
