Test a pair from each table by substituting their values into the given equation and solving.
A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1
B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1
C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1
D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1
The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.
65x+75=495
-75 -75
65x=420
65/65 420/65
X=6.46
No, he has not watched the whole movie. The answer would be D. he only has 2/15 to watch.
Hope I helped!
We will have the following:
From the graph we can see that they are in "balance" and thus each side of the balance for each pair will be equal to 1/2, thus:
Triangle = 1/2:
2Square = 1/2 => Square = 1/4.
Same for the other side:
3Flowers = 1/2 => Flower = 1/6
4Pentagons = 1/2 => Pentagon = 1/8.
That is:

y' = 1 + sec^2(x),

cosπ=−1</span><span>
plug in pi = -1 ,for x:
1 + sec^2(pi) = 1 + (-1)^2
= 2</span>
