Answer:
-x
Step-by-step explanation:
12x-13x is -1x which can also be written as -x
Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
Answer:

Step-by-step explanation:
We want to evaluate:

This is the same as:

We integrate to obtain:

We evaluate to obtain:

If your still using number blocks then it is 20 ones but if its just addition or so it is just 20
