Over the last 3  evenings, Keisha received a total of 81  phone calls at the call center. The first evening, she received 6  few
tensa zangetsu [6.8K]

Answer:

First: 15

Second: 21

Third: 45

Step-by-step explanation:

In order to create the equation we need to represent the evenings with an alebraic term, in thsi case we are going to represent the second evening with an X

Second evening:x

The first night she got 6 fewer calls than the second: Second-6=x-6

The third night she received 3 times the first: 3(first night)=3(x-6)

The equation is First Night plus second night plus third night equals 81.

First+second+third=81\\x+(x-7)+3(x-6)=81\\x+x-7+3x-18=81\\5x=81+21+6\\5x=105\\x=\frac{105}{5} \\x=21

So the first evening he received 15 calls, the second he received 21 and the third one he received 45.

Which is the correct answer?
gayaneshka [121]

Answer:

The correct answer is y = 12x + 9

Step-by-step explanation:

There is a formula called y = mx + b where m is the slope and b is the y-intercept

The y-intercept is 9 so y = mx + 9

The slope is 12/1 or just 12 so y = 12x + 9
