Y = mx + b
where m = slope and b = y-intercept
You're already given that the slope is 5/2, so put that for m
y = 5/2x + b
To find b, use the ordered pair you're given (-4, -3) and plug -4 for x and -3 for y and solve for b.
-3 = 5/2 * -4 + b
-3 = -10 + b
7 = b
y = 5/2x + 7
The formula for the circumference is:

So to find first radius:

Second radius:

The ratio between them is:
Answer: Hey there! The answer is A!
Step-by-step explanation:
Answer:
First, you add 30 and 20, and you get 50. Then, since 30 is your highest priced item, you find 0.30 of 30, which is 9. After that you would subtract 9 from 30, which gives you 21. Therefore, we know the price is 41
Step-by-step explanation:
You can use 6-2=4
You just Subtract the 2 from 6 and that gives 4
