Which conjecture is valid by the law of syllogism for the following scenario? “if joe buys nancy a card, he will give it to her. if nancy is having a birthday, then joe will buy her a card.”
a. if nancy is having a birthday, then joe will give her a card.
b. if joe buys nancy a card, then she is having a birthday.
c. if joe gives nancy a card, then he bought the card.
d. if joe gives nancy a card, then she is having a birthday.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

1/4 is the answer if i recall correctly.
