Answer:

Sean got 63/81 questions right as a fraction.

Step-by-step explanation:

Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.

Now ask yourself: Can you simplify?

Yes you can.

You divide each number from the fraction by 9.

63 / 9 = 7

81 / 9 = 9

7/9 questions that Sean got correct.

If you also want a percentage + grade, Sean would get 77% which would be a C+

PLEASE HELP WITH GRAPH LAST QUESTION I NEED

SVETLANKA909090 [29]

Answer:

$\sf g(x) = -1(x+3)^2 -2$

Explanation:

$\sf original \ graph: \ y=-x^{2}$

the graph is translated 3 units to the left and 2 units down.

vertex: (-3,-2) point: (-1,-6)

$\sf so \ new \ graph :$

$\sf y = a(x-h)^2 +k$

$\sf -6 = a(-1-(-3))^2 -2$

$\sf -6 = 4a -2$

$\sf 4a = -4$

$\sf a = -1$

$\sf equation:$

$\sf y = a(x-h)^2 +k$

$\sf y = -1(x+3)^2 -2$
