Suppose the line is y=mx+b
when x=3, y=15, so 15=3m+b
when x=-1, y=-13, so -13=-m+b
solve the system of these two equation, you get m=7, b=-6
so the linear equation is y=7x-6
Answer:
week 12
Step-by-step explanation:
not sure if i can read it correctly but it looks like she gets below 120 after 12 lines. plus 130-12 is less than 120
(f +G) means to add the two equations together:
5x - 2 + 2x +1
5x + 2x = 7x
-2 + = -1
Answer is C. 7x-1
Answer:
18
Step-by-step explanation:
We know that line FH total length is 49. We also know that the length of line GH is 31.
To find FG, all we need to do is subtract 49-31 to find the length of FG.
Line FG total length is 18.
Mean and median both try to measure the central tendency in a data set. The mean is commonly used but sometimes the median is preferred.
