Answer:
Step-by-step explanation:
<u>According to data in the table we see pairs of points:</u>
<u>This gives us the rate of change:</u>
- (125 - 75)/(5 - 3) = 50/2 = 25
<u>The y - intercept is zero:</u>
- 75 = 3*25 + b
- 75 = 75 + b
- b = 0
<u>The line is:</u>
This is the line on the graph B
<u>Note.</u> <em>Its not clear what is needed regarding the table on the bottom</em>
2^x-2=16

——————
2^x=18
(Log)(2))=log (18)
X=log(18)

Log(2)
X=4.169925
Step-by-step explanation:
(2x-y+3)(2x-y-3)=
4x²-2xy-6x-2xy+y²+3y+6x-3y-9=
4x²-4xy+y²-9=
(2x-y)²-9
Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that

(<span>8.4852...)
</span>is equal to

(12)
If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.
So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!
