Answer:
(y, -x)
Step-by-step explanation:
Rotation of 90°
(Clockwise)
(x, y) ---> (y, -x)
Rotation of 90°
(CounterClockwise)
(x, y) --> (-y, x)
Rotation of 180°
(Both Clockwise and Counterclockwise)
(x, y) ---> (-x, -y)
Rotation of 270°
(Clockwise)
(x, y) ---> (-y, x)
Rotation of 270°
(CounterClockwise)
(x, y) ---> (y, -x)
Answer: Early in the race, Alberto runs faster. He maintains a speed of 20 km/h, as Bianca running speed ??increases??. The first person to cross the finish line is Bianca.
Step-by-step explanation:
-8k - 8(-8k + 6) = -8k + 64k - 48 = 56k - 48
Answer:

Step-by-step explanation:
To derive the function rule in slope-intercept form,
, we need to find the slope, m, and the y-intercept, b, of the graph given.
Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = -4
The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.
Substitute m = -4, and b = -2 into
.
The function rule in slope-intercept form would be:


Answer:
7x+3
Step-by-step explanation:
2x+y
5x-y+3
Then you solve it by crossing out the y and adding the x’s.
7x+3
