X can be anything you want it to be.
I would stick with something easy for x.
y=4(x)^2
y=4(2)^2
y=4(4)
y= 16
Step-by-step explanation:
(×) x ×2 + 1
x= 2+1
×= 3
3.2 +1 = x
6+1 = 7
×=7
F = (7)
Answer:
To find the perimeter, you actually need to find the circumference of a circle.
Step-by-step explanation:
The formula to find the circumference is:
C= 2 pi times r
The r is the radius of the circle. The 2 stays the same. If you have the radius then you are fine.
E.g. If you have a circle and you're given that the radius the distance from the center to a point on the circle is 10. Since you have the radius, all you will have to do is C= 2 pi times (10). So 2 times 10 is 20 so it'll be 20 pi for the circumference.
I hope this helped sorry if it's confusing. If you have any questions please ask.
D is the answer vaporizing
First, find the slope between the two points.
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation.
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case.
y= 1/3x or in other words y= x/3
