X≥14.5
you make a number line, and number it. make a close circle on top of 14.5, and make an arrow pointing towards the positive (numbers with bigger value)
Answer:
y = 2x + -5
Step-by-step explanation:
If you look at the graph, you can find that the slope is 2/1 which is simply just a slope of 2. The y-intercept can be found x = 0, so plug in 0 for x, solve from there and you get -5 for the y-intercept.

Part 7) ![AB=27\ units](https://tex.z-dn.net/?f=AB%3D27%5C%20units)
Part 8) ![x=1.7\ units](https://tex.z-dn.net/?f=x%3D1.7%5C%20units)
Step-by-step explanation:
Part 7) Find the length of AB
we know that
The<u><em> two tangent theorem</em></u> states that if we draw two lines from the same point which lies outside a circle, such that both lines are tangent to the circle, then their lengths are the same
so
In this problem, applying the two tangent theorem
AB=BC
substitute the given values
![15x-3=10x+7](https://tex.z-dn.net/?f=15x-3%3D10x%2B7)
solve for x
![15x-10x=7+3\\5x=10\\x=2](https://tex.z-dn.net/?f=15x-10x%3D7%2B3%5C%5C5x%3D10%5C%5Cx%3D2)
Find the length of AB
![AB=15x-3](https://tex.z-dn.net/?f=AB%3D15x-3)
substitute the value of x
![AB=15(2)-3=27\ units](https://tex.z-dn.net/?f=AB%3D15%282%29-3%3D27%5C%20units)
Part 8) we know that
If CD is tangent to circle E at point C
then
Line segment CD is perpendicular to line segment EC (radius) and CDE is a right triangle
so
Applying the Pythagorean Theorem in the right triangle CDE
![DE^2=CD^2+EC^2](https://tex.z-dn.net/?f=DE%5E2%3DCD%5E2%2BEC%5E2)
substitute the given values
![2^2=x^2+1^2](https://tex.z-dn.net/?f=2%5E2%3Dx%5E2%2B1%5E2)
solve for x
![4=x^2+1\\x^2=3\\x=1.7\ units](https://tex.z-dn.net/?f=4%3Dx%5E2%2B1%5C%5Cx%5E2%3D3%5C%5Cx%3D1.7%5C%20units)
Answer:
One
Step-by-step explanation:
It is one because each spoke has one space in the middle. However some people think it's 64 because they read the question wrong.
