Simplify by dividing [ -3/-8] divided by 5/9 (5 points)
rewona [7]

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.

Inessa05 [86]
A full circle has a circumference of 2πr and an angle of 2π radians.

Set up a proportion:
2πr - 2π rad
2r - x rad

2\pi r \times x = 2\pi \times 2 r \\
2\pi r x=4 \pi r \\
x=\frac{4 \pi r}{2 \pi r} \\
x=2

The answer is D. 2 radians.

Find the equation of the line parallel to y = -3x + 4 with a y-intercept of -10
rosijanka [135]
The correct answer is y=-3x-10

when a line is parallel to another line that means the slip of the lines are going to be the same and since the y-intercept of the other line was given to you, you would just put them together in one equation.
