Answer:
plug in -3 and 2 into the equations you should get two different numbers
Step-by-step explanation:
3(-3)+2(-3)=24
3(2)+2(2)=24
<u>ANSWER</u>
(C) y
<u>EXPLANATION</u>
We have two equations:
The first one is
The second equation is
Let us make z the subject of this second equation:
We now add equation (1) and (3) to get:
We simplify to get:
Divide throu by 2.
The correct answer is C
The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant. As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.
Then, the function is defined only for positive values of w and H(w) is always positive.
Then, the answer is H(w) > 0, this is the option C.
