Answer:

y = 2x, y = 2x + 3

Step-by-step explanation:

When a line is dilated by a factor of "a", we multiply that by "a".

So when we dilate y = x by a factor of 2, the resulting equation is:

y = 2*x

y = 2x

When we translate "b" units up the resulting equation would be

y = x + b

Since we have y = 2x, now we will translate 3 units up, so it becomes:

y = 2x + 3

A survey of 285 adults found that during the last year, 75 traveled by plane but not by train, 55 traveled by train but not by p

meriva

Answer:

Step-by-step explanation:

Given that

Total number of adults, U = 285

Number of plane travellers, P = 75

Number of train travellers, T = 55

To find the number of people that didn't travel by any means of transportation listed in the question, then we say

Total number of adults minus number people who traveled by plane or train minus number of people who traveled by bus but not by plane or train.

This means that number of people who didn't travel by any of the three means of transportation, N =

N = U - pt - b

N = 285 - 215 - 30

N = 40

Therefore, the total number needed is 40

For what value of a is (a,9) a solution for the equation y=2x+1?

Ivahew [28]

Answer:

Step-by-step explanation:

(a,9).......we dont know " a " (or x) but we do know y...it is 9

so sub in 9 for y and solve for x

y = 2x + 1

9 = 2x + 1

9 - 1 = 2x

8 = 2x

8/2 = x

4 = x <======= ur answer is D
