Since the original coordinates are (-3,4), you can start finding the prime coordinates by adding 3 to the x-value, and subtracting 2 from the y-value. This will get you (-3+3, 4-2) This will come out to (-0, 2), so your answer will be...
D. C'= (0,2)
I think it's :
Part A ; $30 * (x) + $13
$28 * (x) + $15
Part B ; so $30 * 4 + $13 = $133 vs.
$28 * 4 + $15 = $111 so that would mean company B Would charge the least amount.
Part C ; the difference between company a and company B prices is $22.
The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.
