on-the-go phone company have two monthly plans for their customers. the ez plan costs $0.15 per minute. the 40 to go plan cost $40 per month plus $0.05 per minute.
a. write an equation to represent the point at which the monthly bills for the two plans are equal
b. which plan would you use if you wanted only 200 minutes per month?

(a)400min

(b)EZ plan

Step-by-step explanation:

Given

For EZ plan cost $0.15 per minute

and Go Plan cost $40 + $0.05 per month

so for t minutes in a month both plan cost equals when

0.15t=40+0.05t

0.1t=40

t=400 minutes

for 400 minutes both cost equal.

(b)For 200 minutes

EZ plan cost

GO plan costs

So for 200 minutes we can use EZ plan

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
