Answer:
What is the degree of rotation that takes quadrilateral FGHI to F'G'H.
Step-by-step explanation:
In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)
So far he has 63+72+88+91= 314
400-314=86
He needs to get 86 points from the last test.
Since he is obviously getting better at tests, i think he'll manage :)
Answer:
<em>a = 6 </em>
Step-by-step explanation:
g(x) = 5x - 2
h(x) = √(x + 3)
g(h(x)) = 5
- 2
g(h(a)) = 5
- 2
5 - 2 = 13
5 = 15
= 3
( )² = 3²
a + 3 = 9
<em>a = 6</em>
The formula is (x1+x2)/2 will give you the x of the mid point.
(y1+y2)/2 will give you the y of the mid point.
So, (3+9)/2= 6
And (6+8)/2=7
The mid point is (6:7)
