Answer:
The discount would be 4.2$ while the ending sale price would be 16.8 since it's 21
Step-by-step explanation:
You multiply 21 by .20 finding you 4.2, then you subtract that from 21 to find 16.8
Answer:
-1
Step-by-step explanation:
Because 8-9=-1
Answer:
slope = 1 and y intercept is (0,3)
Step-by-step explanation:
This equation is in the form y= mx+b where m is the slope and b is the y intercept
y =1x +3
The slope is 1 and the y intercept is 3
slope = 1 and y intercept is (0,3)
180° rotation about the origin
Answer:
U'(3, -6), V'(8, -1), W'(3, -1)
Step-by-step explanation:
According to the 180°-rotation rule, you take the OPPOSITE of both the y-coordinate and x-coordinate:
Extended Rotation Rules
270°-clockwise rotation [90°-counterclockwise rotation] >> (x, y) → (-y, x)
270°-counterclockwise rotation [90°-clockwise rotation] >> (x, y) → (y, -x)
180°-rotation >> (x, y) → (-x, -y)
