If your teacher taught rise over run, then for the graphs:
y=-1/2x+1
start at y intercept of 1, then down 1, right 2 all the way, same for the other side but reversed.
y= 1/3+6
start at y intercept of 6, then up 1, right 3 all the way, same for the other side but reversed.
One solution: (-6,4)
Based on the emperical rule
the distribution will be as follows
btwn 80 n 85 on the test - 34%
btwn 80 n 95 on the test - 82%
below 85 on the test - 50%
<span>above an 80 on the test - 84%</span>
X >- 5
-2x -4 < 3x +21
+4 +4
-2x < 3x +25
-3x -3x
-5x < +25
-5x/-5 25/-5
X > -5
Answer:
so it would be f=36
Step-by-step explanation:
subtract 4 to the other side then multiply both sides by 3
Hello :
sin<span>θ = 15/17
</span> use pythagorean identity : cos²θ +sin² θ = 1
cos²θ = 1 - sin² θ
cos²θ = 1-(15/17)²
cos²θ = 1- 225/289
cos²θ = 64/289
cos²θ = (8/17)²
cosθ = 8/17 or -8/17
