Earl charges $50 for a house call and $40 per carpet cleaned. Ray charges the
same amount per carpet cleaned, but his total cost is always $30 less than Earl's. Which equation expresses the total cost, t, for Ray to
clean as a function of carpets cleaned, c?
Answers
Answer:
t= 20+40c
Step-by-step explanation:
Given that Ray's total cost is always $30 less than Earl's and they charge the same amount per carpet cleaned, the difference is in the amount charged for a house call and to find that amount you have to subtract 30 from the amount Earl's charges:
50-30=20
This means that Ray charges $20 for a house call and $40 per carpet cleaned. According to this, the equation would indicate that the total cost for Ray is equal to the amount he charges for a house call plus the price per carpet cleaned for the number of carpets cleaned, which would be:
t= 20+40c, where:
t is the total cost
c is the number of carpets cleaned

Answers
Answer:
A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, translation and dilation.
Rotation is the turning of an object about a point. If a point A(x, y) is rotated 90 degrees counterclockwise about the origin, the new point would be A'(-y, x)
From the image attached, the coordinates of polygon ABCD is A(1, 1), B(1, 2), C(2, 2), D(3, 1). If polygon ABCD is rotated 90 degrees counterclockwise about the origin, the new vertices would be at A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).
