Answer:
Option C.
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
Find the value of the constant k
For the point (-8,-6)

For the point (12,9)

<u><em>Note</em></u> A single point was required to find the constant k (because the line passes through the origin)
The equation is equal to
Answer:
As you noted, ∠PRS=80°. Take the triangle △TRS: we know two angles out of three, so that ∠TSR=45°. Now take the isosceles triangle △PTS: the two angles adjacent to the base PT are equal to 35°, so the third angle ∠PST=110° and then ∠PSR=65°. This is one of the two angles adjacent to the base of an isosceles trapezoid: knowing it, you can easily complete the solution.
Answer:
No solution.
Step-by-step explanation:
8x - 4 = 2(4x - 4)
8x - 4 = 8x - 8
-4 = -8
-4 ≠ -8
The denominator in each term of the series is a square number, but neither

nor

are squares. So none of (1), (2), and (4) can be correct. The answer must be (3).
Answer:
B (6,0) because when graphed it would make a 90° angle
