Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are the coordinates of B' after the translation?

Step-by-step explanation:

Given

Translation: 3 units left and 1 unit right

Required

Determine the new coordinates of B

Write out the coordinates of B

When a function is shifted to the left, we have to subtract the unit from the x value of the function;

Shifting by 3 units left, the new x becomes

When a function is shifted upward, we have to add the unit to the y value of the function;

Shifting by 1 unit up, the new y becomes

Hence, the new coordinates of B is

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

47 - 90 = 43

43 - 180 = x

x = 137
