Step-by-step explanation: First, let's graph this down.
With all the points touching except (-2, -6) and (8, 18), it's safe to say that these are the coordinates that have to be removed. Also, just for an extra help, the linear line is 2x + 1 = y
X=6 if you need an explanation commu
The answer would be "true"<span />
Answer:
Comic Books
a: y=-10x+90
b: He will have 10 books at the end of the seventh day.
Step-by-step explanation:
A: Take two points. The y-intercept is (0,90). The graph decreases by 10 each day.
B: Look at day 8.
So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:
5 to 10
We would change this into:

Because the problem says to simplify, we can divide both sides by 5 and simplify it into:

If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.
