Answer:
radius= 7
Step-by-step explanation:
the radius is half of the diameter.
i hope this helps :)
So first, you have to get two of the same variables to cancel out. Let's do this for x. In order for the x's to cancel out, we could multiply the bottom problem by 2.
(2) 3x-6y=24
After multiplying all the numbers by 2, you get the equation 6x-12y=48
The set of equations is now
-6x+2y=12
6x-12y=48
Now you can add them. The x variables cancel out, so you are left with the y variable.
2y+-12y=-10y and 12+48=60
Then you would divide 60 by -10 to get y=-6.
You would plug the answer for y into one of the original equations, lets do the top one. -6x+2y=12 becomes -6x+2(-6)=12
You'd multiply the 2 and -6 to get -12 so the equation is
-6x-12=12
The negative 12 turn positive and you add to both sides to get the -6x alone.
-6x-12=12
+12=12
-6x=24
Then divide 24 by -6
X=4
(-4,-6) is your final answer.
Answer: 24
Work: 4x= 4•12, yz = 8•3, so you have to do 48 (4 times 12) - 24 (8 times 3)
It is the distance the number is from 0
The value of m for the new line given by the equation y = mx + b would be -1/5
Assuming the y intercept of the new line would be the same, the equation of the new line would be.
Y = -1/5x-2.
