Answer:
4(x+4)
Step-by-step explanation:
Find to GCF of 4x+16.
Now factor out the GCF by dividing each term in the expression by 4.
4x divided by the GCF is x, and 16 divided by the GCF is 4.
The equivalent expression is 4(x+4).
You have:
2r

6r-21
then move the 6r over to the left and you end up wtih
-4r

-21
Then you divide by -4 and when you do you must flip the inequality so your answer would be
r

21/4
You need to solve for x or y in one equation and and substitute it into the other equation in place of the variable that corresponds to it.
Answer:
x=4
Step-by-step explanation:
The answer is 2 because on the graph the line descends by 1 creating the “slope” which is your x value. then the y intercept means that the line always goes through y and where it meets which is 6. think to it as y=mx+b m is your slope with x plus the crossing point on the y intercept
