Answer:
B & D
Step-by-step explanation:
(-12,0) & (-10,1)
Hey there! :)
(0, 2) & (-1, -2)
Slope-intercept form is : y=mx+b , where m=slope, b=y-intercept
First, we must find the slope using the slope formula, which is :
m = y2-y1/x2-x1
Where y2 = -2 ; y1 = 2 ; x2 = -1 ; x1 = 0
Now, let's plug and chug! :)
m = (-2 - 2) / (-1 - 0)
Simplify.
m = -4/-1 --> Therefore, our slope is : m = 4
Now that we have the slope, we can plug this (and our original coordinates) into point-slope form, which is : y - y1 = m(x - x1) -> use the coordinates (0, 2)
y - 2 = 4(x - 0)
Simplify.
y - 2 = 4x
Add 2 to both sides.
<u>y = 4x + 2</u>
Hope this helped! :)
<span>the smaller angle is 2x = 2 times 18 = 36 degrees.
the larger angle is 3x = 3x = 3 * 18 = 54 degrees.

Answer:
1.
Experimental : or 56%
Theoretical : or 50%
2.
22 customers
Step-by-step explanation:
Theoretical is how many times you'd expect it to land. So for coin flipping it would be either heads or tails. The probability it would land on heads would be 50% because it's either one or the other.
Experimental is how many times you actually landed it. You flipped a coin and it landed on heads 28 times, so you can put that over 50.
Since can be simplified to or 56%, that is the experimental probability.
For the second variation, we can assume that it is direct variation.
When increases, increases.
Let's solve for .
We can plug that in to the second equation since we already know how many customers there will be.
Answer:
False.
Step-by-step explanation:
A complementary angle is an angle where two seperate angles add together for a 90 degree angle. They usually share a side, but not always.
