Well -7+17 would equal 10. Hope this helps!
4. However, you can do this in a Calculator.
Diameter- The line that goes through the circle is the diameter to find the diameter take the radius and multiply it by two
Circumference- Take the radius divide by two and multiply by pi which is 3.14
Answer:
B: {(3,1), (7,9)}
Step-by-step explanation:
For equation 2x-y=5, we can isolate y, so it's easier to solve later:
y = 2x - 5
y = (x - 4)^2
Now, notice that both equations are equal to y, so we can set them equal to each other:
(x-4)^2 = 2x-5
x^2-8x+16 = 2x - 5
x^2-10x+21=0
Now, we can factorize by finding 2 numbers that multiply to 21 and add up to -10:
(x-3)(x-7)=0
x=3 or x=7
Since B is the only one with the x values of 3 and 7, the answer must be B.
But to further check our answer, we can plug x back to any of the equations above to check for y:
(3-4)^2 = 1
(7-4)^2 = 9
Therefore, we can confirm that the answer is B.
Answer:
r = 13
Step-by-step explanation:
The first step is to find b from y=mx=b using m=4/3 and (-4,8)
After solving the equation, b will equal -16/3 making the final equation be
Using the equation, you can solve for r.
This will bring the answer being r = 13
