An unknown number y is 20 more than an unknown number x. the number y is also x less than 2. the equations to find x and y are shown below:

y = x + 20
y = –x + 2

which is a correct step to find x and y?

multiply the equations to eliminate y.

add the equations to eliminate x.

write the points where the graphs of the equations intersect the x-axis.

write the points where the graphs of the equations intersect the y-axis.

What is the multiplicative rate of change of the exponential function shown on the graph?

Acircle has a circumference of 2 pi cm. which statement about the circumference and area is true? a comparison of the area and circumference is not possible since the area cannot be determined. the numerical values of the circumference and area of the circle are equal. the numerical value of the circumference is greater than the numerical value of the area. the numerical value of the circumference is less than the numerical value of the area.

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.
