Answer:
a
Step-by-step explanation:
25 times x = the 25 dollars for each week totaled
+50 he already had = y
The missing angle is ninety degrees (Brainliest please)
Answer:
A
Step-by-step explanation:
This is how I write
y=kx+m
but I have seen some write it like this:
y=mx+b
Well both of them are the same thing, I'll use the first one because I'm more comfortable with it.
y=kx+m
To find out what k

So you first need to choose two points.
I'll go for (0,-5) and (2,0)


Now you could insert k into the equation and it will look like this.

To find out what m is just pick one point and insert it into the equation. So if I pick (0,-5). 0=X therefore it should be replaced by x and -5=y therefore it should also be replaced by y.

m=-5
Try it with another point to see if you get the same answer. this time I'll pick (-6,10)

m= -5
The equation will be y=-5/2x-5)
Answer : SSE = 9
r^2 = 0.75
r^2 = 1 - (SSE/SST)
SSE/SST = 1 - r^2 = 1 - 0.75 = 0.25
<span>SST = 9/0.25 = 36</span>
The answer is System 2 and system 3, because the second equation in system 3 is
obtained by adding the first equation in system 2 to two times the
second equation in system 2, i just took the test.
