Answer:
52
Step-by-step explanation:
everytime it adds by 9:
7+9=16
16+9=25
25+9=34
34+9=43
<u>43+9=52</u>
Answer: (3, 8)
<u>Step-by-step explanation:</u>
- <u>x | y</u>
- <u>3 | 8</u>
- <u>6 | 6</u>
- <u>7 | 8</u>
- <u>9 | 12</u>
Notice that y=8 when x=3 and when x=7, so this is either a parabola or an absolute value function.
The axis of symmetry passes the midpoint of x=3 and x=7 so the axis of symmetry is x = 5.
(6,6) is given. It's mirror image <em>across the axis of symmetry</em> is (4, 6).
Similarly, (9, 12) is given. It's mirror image is (1, 12).
And (7, 8) is given. It's mirror image is (3, 8). This is the only pair available as given options for this question.
<em>Side note: Notice that the slope between (6, 6), (7, 8), and (9, 12) is the same (equal to 2) so this is the graph of an absolute value function.</em>
Answer:
-88
Step-by-step explanation:
-a² + 4ab - b²
Substitute the variables with the numbers given.
-2² + 4(2×-6) - -6²
-2² + 4(-12) - -6²
-4 + 4(-12) - 36
-4 + -48 - 36
-52 - 36 =
-88
(im starting 8th grade tommorow and im doing this cause im bored and i should practice xD)
The answer would be D. The law of cosines.
