The answer is b) y = 3x + 3.
To find this, we first need to find the slope. The slope formula is listed below.
m = (y2 - y1)/(x2 - x1)
In this equation, m is the slope, and (x1, y1) is the first point, where (x2, y2) is the second point. We'll use (2, 9) and (3, 12) for the points.
m = (y2 - y1)/(x2 - x1)
m = (12 - 9)/(3 - 2)
m = 3/1
m = 3
Now that we have the slope at 3. we can use slope intercept form and one point to solve for the y-intercept. We'll use (2, 9) as the point.
y = mx + b
9 = 3(2) + b
9 = 6 + b
3 = b
When we use the slope and intercept together to get the equation. y = 3x + 3

Step-by-step explanation:
Use the formula for a semicircle's perimeter.
![P=\frac{1}{2}\pi *d+d](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B2%7D%5Cpi%20%2Ad%2Bd)
Plug in 6 for d.
![P=\frac{1}{2}\pi*6+6](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B2%7D%5Cpi%2A6%2B6)
Let's use 3.14 for
, just to make it easier, but of course, if it states to round it to something else, just plug in that many values for
.
![P=\frac{1}{2}(3.14)*6+6 \\ \\ P=1.57*6+6 \\ \\ P=9.42+6 \\ \\ P=15.42](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B2%7D%283.14%29%2A6%2B6%20%5C%5C%20%5C%5C%20P%3D1.57%2A6%2B6%20%5C%5C%20%5C%5C%20P%3D9.42%2B6%20%5C%5C%20%5C%5C%20P%3D15.42)
Multiply the numerator and denominator by √2
10√2/2

Answer:
$26.91
Step-by-step explanation:
9.50 +13.93 =23.43
50.34 - 23.43 = 26.91
An integer divided by its opposite always equals -1: this is false. Any number which is not 0 divided by it's opposite is in fact equal to -1, but since 0 is also an integer, it's false. You are right, good job!
