Answer:
In the first equation, it's H20 but the second is B

<span>Use the Pythagorean theorem for the right triangle

where

is the hypotenuse of the triangle;

and

are the other two sides.
So,

From these -Tx+y=S. If -T=Q/R, then y=-Qx/R+S, so Ry=-Qx+RS, Qx+Ry=RS=S.
If R is not equal to 1, or S is non-zero, the equations are inconsistent, so there would be no solutions.
If R=1 there are an infinite number of solutions given by Qx+y=S, or y=S-Qx or y=S+Tx.
If S=0, Qx+Ry=0 or y=-Qx/R or y=Tx.
Answer: The range is 16 :)
Step-by-step explanation:
The lowest number is -9 and the highest is 7. the difference between those is 16.
Answer:
The answer is A
Step-by-step explanation:
By looking at the graph, the y-intercept is -1. So, the answer must be A or C.
Then we can look at the the graph, you can see the line is left up right down. So the equation will be negative, which is A.
