It would be y=x+3 because you have a slope of 1 and a y-intercept at 3
Answer:
A+3B=4+5r
Step-by-step explanation:
Given that,
A = 1+r+7r
B = 1-r
We need to find an expression that is equal to A+3B.
Putting the values of A and B in A+3B, we get :
A+3B = 1+r+7r + 3(1-r)
=1+8r+3-3r
=(1+3) +(8r-3r)
=4+5r
Hence, the values of A+3B equals 4+5r.
There are 1010 possibilities for the 1010 sided die and 66 possibilities for the 66 sided die. Please mark Brainliest!!!
First we are going to group the terms that contains the common factor

in one parenthesis, and the other ones in another parenthesis:


Notice that our the terms in our first parenthesis have a common factor

, and the terms in our second one have the common factor

. Lets factor those out:

Now we have a common factor

in both terms, so we can factor those out as well:

We can conclude that the completely factored expression ordered alphabetically is

.
