Answer:
(4,-3)
Step-by-step explanation:
If you graph this point, then it will be in the 3rd quadrant.
A 180 degree rotation will put it in the 1st quadrant.
And the extra 90 degrees will put in in the 4th quadrant, so we know that in (x,y), x is positive, and y is negative. then if you theoretically rotate it, since you are rotating it 90 degrees, 3 times, you will have to switch the x and y, since 3 is an odd number. so the final answer is (4,-3).
Answer:
The measure of angle D is of 66º.
Step-by-step explanation:
Vertical Angles:
If two angles are vertical, they have the same measure.
In this question:
Angles C and D are vertical.
Angle C measures 66º.
So the measure of angle D is of 66º.
Answer:
y = 48/x
Step-by-step explanation:
"Inverse variation" means y is proportional to the inverse of x. If the constant of proportionality is represented by k, then ...
y = k/x
Multiplying by x, we find k to be ...
xy = k
So, the given values tell us k is ...
8·6 = k = 48
and the desired equation is ...
y = 48/x
The function goes through (0,9) (6,5.4) and (15,0)
