-3(r-9s=2)+(3r-3s=-10)
24s=-16
s=-2/3, now using either original equation we can solve for r.
3r-3s=-10 becomes:
3r+2=-10
3r=-12
r=-4 so the solution is the point:
(s,r)=(-2/3, -4)
Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
The answer would be 280 as a tens bar is worth ten. 28x10=280
Answer:
the value of the z is -3.5
Step-by-step explanation:
According to the question, the following information is given
-2z - 7
Based on the above information
We assume that we have to determine the z value
so
-2z - 7 = 0
-2z = 7
z = 7 ÷ -2
= -3.5
Hence, the value of the z is -3.5
The same is to be considered and relevant too
