Answer:
- Add 1 to both sides.
- Distribute the 4
- Subtract 8 from both sides
- Divide both sides by 12
I hope this helps!
pls ❤ and give brainliest pls
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 = mx + b
The product of slopes of perpendicular lines is -1. The slope of the given line is 2, so the slope of the perpendicular line is -1/2.
y = (-1/2)x + b
Now use the given point to find b and finish from here.
-5 = (-1/2)(2) + b
b = ?

8/16
Step-by-step explanation:
(8÷8)=1 / (16÷8)=2 = 1/2
Answer:
2<k
Step-by-step explanation:
