Does the equation y = 20x + 500 represent a linear function

Yes

Step-by-step explanation:

The equation for slope intercept is y=Mx+b . M= the slope, which in this case is 20. B= the y-intercept, which is 500. Therefore the answer is yes.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

47 - 90 = 43

43 - 180 = x

x = 137
