Answer:
22.5m
Step-by-step explanation:
450m²÷20m=22.5m
Use the slope formula.
m = slope = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(0 - (-1)) = 3/1 = 3
It is B and C. The answer is B and C or B and D
13°, 66°, and 101° ......
Answer:
P' = (4, 4)
Step-by-step explanation:
T(x, y) is a function of x and y. Put the x- and y-values of point P into the translation formula and do the arithmetic.
P' = T(8, -3) = (8 -4, -3 +7) = (4, 4)
_____
<em>Comment on notation</em>
The notation can be a little confusing, as the same form is used to mean different things. Here, P(8, -3) means <em>point P</em> has coordinates x=8, y=-3. The same form is used to define the translation function:
T(x, y) = (x -4, y+7)
In this case, T(x, y) is not point T, but is <em>a function named T</em> (for "translation function") that takes arguments x and y and gives a coordinate pair as a result.
