Answer: just figure out how many 8s are in 36 then multiply that by 66 :):)
Step-by-step explanation:
I’m not sure about number 9. But number 10 is answer C. This is because there are two sides to a coin, so you are equally likely to land on heads as you are tails. So you take 64 and divide it by 2, and get the answer 32.
Answer:
y = -2x-5
Step-by-step explanation:
So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b
To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.
So y=-2x-5.
I believe A, not 100% sure though
