Answer:
2n+7
Step-by-step explanation:
+2 +2 +2 +2
9 11 13 15 17 so we start with 2n
2 ➡ 9 = +7 6 ➡ 13 = +7
4 ➡ 11 = +7 8 ➡ 15 = +7
So the answer is 2n + 7
Answer:
N = 3
Step-by-step explanation:
If 6 = 1 and n = 1/2 then n is 1/2 of 6
6/2 = 3
Answer:
Yes
Step-by-step explanation:
1) Cos 300 = Cos (360 - 60) = Cos 60 {Cos 360 - theta = Cos theta}
= 1/2
Sin 300 = Sin (360 - 60) = -Sin 60 = 
3) 3π/4 = 3*180/4 = 135
Cos 135 = Cos (90 + 45) = -Cos 45 = 
Sin 135 = Sin (90 + 45) = Sin 45 = 
Answer:
y= -4/5x+33/5
Step-by-step explanation:
for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.
x1=7 and y1=1
x2=-3 and y2=9
now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5
now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.
to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).
1= -4/5 x 7+b. b= 33/5
HOPE THIS HELPS!!
