Answer:
B
Step-by-step explanation:
4x12=48/2x2=B or 48
Answer:
A
Step-by-step explanation:
y = 4x - 4 is a line with y-intercept -4 and slope 1. Both graphs A and C show that line in blue.
y = 4 is a horizontal line through y = 4. Graph A shows that line.
Answer: A
Answer: Gear B turns 90 times when gear A turns 60 times
Step-by-step explanation: To solve this you just 30x3=90
Perpendicular lines have slopes that are negative reciprocals of each other, so the equation of the line in point-slope form is:

Rewriting this in standard form,

Answer:
36º
Step-by-step explanation:
The sum of a triangle's angles is 180. So, 6x+2x+2x=180. And, 10x=180, and then x=18. Angle C is 2x. To find angle C multiple 18 by 2 to get 36.
