The answer would be 40.
Do 69-9 which gives you 60. And then 2/3 / 60 (divide 60 by 3) and you get 20. 20*2=40
X-intercept appears at when y = 0
So when cos(0.5x) = 0 -> 0.5x = pi/2 + n*pi, where n is any random integers
So x = pi + 2npi, so the angle can be pi, 3pi, 5pi, so on
Y=8x
Ask for a step by step explanation. :)
Hope this helps.
Answer:
what.....
Step-by-step explanation:
3 if 5 times a number plus two is 17, then we can say 5x+2=17 if we subtract two on each side we have 5x=15, divide each side by 5 and you get x=3 so your answer is 3
