4x + 8y = 32
To find the x-intercept, replace y with 0.
4x + 8(0) = 32
Then simplify to find x.
4x = 32
4x/4 = 32/4
x = 8
To find the y-intercept, replace x with 0.
4(0) + 8y = 32
Then simplify to find y.
8y = 32
8y/8 = 32/8
y = 4
x-intercept = (8, 0)
y-intercept = (0, 4)
Answer:
540 degrees
Step-by-step explanation:
The cosine of an angle on a unit circle yields the x value. Therefore, wherever the x value is -1, cos O is -1. Cosine is equal to -1 at 180 degrees, and every 360 degree interval after that. Since 180 degrees is not an option, we need to try the next interval of 360. 180+360=540 degrees, which is one of the options. Hope this helps!
Answer:
27,830
Step-by-step explanation:
Simply move the decimal to the right five digits.
So from 0.2783 to 2.783 to 27.83 etc. until you get 27,830
