Answer: y = 3x-8
------------------------------------------------
------------------------------------------------
Explanation:
The slope is 3, so m = 3
The given point is (3,1) meaning x = 3 and y = 1. The x coordinate is always listed first in an ordered pair. The general format is (x,y)
We'll use m = 3, x = 3 and y = 1 to find the y intercept
y = mx+b
y = m*x+b
1 = 3*3+b ... plug in m = 3, x = 3 and y = 1
1 = 9+b
1-9 = 9+b-9 ... subtract 9 from both sides
-8 = b
b = -8
----------------
So we're given m = 3 as the slope and we just found that b = -8 is the y intercept
So y = mx+b updates to y = 3x-8. This is the final answer.
----------------
Side Notes:
* The slope of 3 means rise/run = 3/1 indicating each time we go up 3, we move to the right 1
* The y intercept -8 is the location on the vertical y axis numberline where the graph crosses. The point (0,-8) is on this line.
Answer:
Apple A
Step-by-step explanation:
Apple A 6.90/6 = <u>1.15 lb</u>
Apple B 12oz/ (16oz or 1lb) =3/4 .90/(3/4) =<u>1.2lb</u>
Apple C 0.45/(1/4)= <u>1.8lb</u>
8.8 million is the right answer
Answer
Step-by-step explanation:
first off rt(2x^5) can be simplified as x^2 rt(2x) because we can break up x^5 into x^4 * x. x^4 is a perfect square so factor out a x^2.
the denominator 
can be written as 
since the factors of 18 involve a perfect square of 9. 9*2 is 18 so factor out a 3.
the whole fraction :
cancel out the 
and you are left with
