Which equations results from adding the equations in this system?<br> x+6y=9<br> -x+2y=-15
UkoKoshka [18]

Answer:

8y = -6

Step-by-step explanation:

Simply add the equations as you would numbers.

The 'x's cancel each other out. The 'y's add together as normal numbers.

9 + (-15) = -6

If f(5)=<br> 3, write an ordered pair that must be on the graph of y = f(x + 1) + 2
vlabodo [156]

f(5) = 3 means (5,3) is on the graph of f.

On the new graph, y = f(x+1) + 2, what do the +1 and +2 do?

Things inside the function notation inpact the x-values, since that's where x sits.

This outside the f(x) notation impact the y-values, since those are done after you've evaluated the function.

"+1" on the inside shifts every point to the left 1 unit.  (Inside changes are almost always opposite from what it looks like it would do.)

"+2" on the outside will shift every point up by 2 units.

So what do you get if you take (5,3) and shift it left 1 and up 2?

What is the value of 8 in 8.644.58
Maslowich
So for the first 8, we need to find the value. The way I would find the value would be to find it's place value. So I know that the 8 is in the millionths period. So the value of the eight would be in the millionths. So I think it would be 8,000,000. So that would be the answer. The 8's value is 8,000,000 because of it being in the millionths period.

Hope that helped! :D
