Answer:

Step-by-step explanation:
To find the answer we have to first group the like terms:

therefore

so

Answer:
b = -9.
Step-by-step explanation:
The line passes through (4, 3) and (7, 12). First, we need to find the slope: the rise over the run.
(12 - 3) / (7 - 4) = 9 / 3 = 3.
Now that we have the slope, we can say that m = 3. So, we have an equation of y = 3x + b. To find b, we can use M(4, 3) and say that y = 3 and x = 4.
3 = 3 * 4 + b
b + 12 = 3
b = -9.
Hope this helps!
The answer is 8n^2
2x2 is 4 x 2 is 8 two n variables so multiple it by 2 and you get your answer
Write the number out:
ex) 2 dots on number 3 so write number 3 twice and etc
3,3,4,5,5,5,6,8,8
find the middle number
5 is the middle number so it’s the median
The answers are C and B.
Answer A has infinite solutions, and D has no solutions
