Answer: 74 Degrees
Step-by-step explanation: We know that a circle is 360 degrees, so take 360 minus measure of AB, which we know is 286, so we get 74 degrees. (ONLY if ABC from a circle.)
Hello there!
The formula for finding the circumference of a circle is 2

r (or 2*3*r in your terms). Although we don't have the radius yet, we can certainly find it pretty easily. Keep in mind that the radius will always be half the diameter. So, let's find the radius.
8 / 2 = 4; now we have everything we need to solve for the circumference.
2*3*4 is our expression. Now let's simplify it.
2 * 3 = 6
6 * 4 = 24
Your circumference is 24cm.
I hope this helps!
Answer:
y= 7/10x -1
Step-by-step explanation:
Assuming you want the equation is slope intercept form, this is the format for slope intercept: y=mx+b. Since you have the slope, this is your current equation: y=7/10x+b. Next, you want to find the y-intercept. So, plug in the coordinate to the equation. This is what it should look like: -1=7/10(0) +b/ Multiply 7/10 by 0 to get 0. So, here is what you're left with: -1=b. -1 is your y-intercept. Go back to your original equation and plug in the -1. This is your final answer: y= 7/10x-1. Hope this helped!
