The correct answer is three.
Answer:
1: D
2: B
3: y=-4x+22
4: y=-8x+26
Step-by-step explanation:
1: Parallel lines have the same slope, and the only one with a slope of 3x is D
2: Perpendicular lines have an opposite slope, so a line with a slope of -1/2 would be 2, so you just flip the number and add or take away a negative sign, depending on the original slope
3: Like I said before, perpendicular lines have an opposite slope, so the slope would be -4. After you've figured that out, you just plug in the numbers given to you (and remember, x is first, y is last)
Plug in: 6=-4(4)+b
You would then solve for b.
6=-16+b
22=b
Then plug that into y=mx+b, with m being the slope (-4) and b being the y intercept (22)
4: The process for finding parallel and perpendicular lines is very similar, except you don't have to change the slope.
Plug in: 10=-8(2)-b
10=-16+b
26=b
Again, plug that into the equation y=mx+b
Hope I could be of help! Sorry if it doesn't make sense, this is my first time on this website.
Answer:
6.25 times 100 will equal to 625. When you multiply by 100, you can move the decimal two spaces to the right since there are two zeros, and you get 625.

I hope this helped you!
If it did, could you please mark me brainliest? That would help me!
Thank you so much! ;) :)
Answer:
x= 20
Step-by-step explanation:
1. multiply both sides by 20: 16x-5x= 220
2. Combine like terms: 11x=220
3. Divide: x=20
Answer:
E. 2.
Step-by-step explanation:
The sphere will have a diameter equal to the side length of the cube.
The side length of the cube is ∛64 = 4 so the diameter of the sphere = 4.
The radius = 1/2 * 4 = 2.
