Explanation:
The general form of a slope intercept equation is y = mx+b
m = slope
b = y intercept
Something like y = (-7/6)x + 1 matches with y = mx+b such that m = -7/6 is the slope and b = 1 is the y intercept. So that's why problem 1 matches with choice b (in column B).
Similar situations apply for problems 2 and 3
-----------
For problem 4, we can see the slope is m = -1, but unfortunately m = -1 isn't listed in column B. However, m = -7/7 is listed. So this is why problem 4 matches with choice a. This leaves problem 5 to match with choice e.
note: 6/7 = 12/14 after multiplying top and bottom by 2.
Answer:
Nina
Step-by-step explanation:
(3+|-2|):2=5/2 i think it's right.
First we write the expression:
((x / 3) - (y / 4)) / ((x / 4) + (y / 3))
We multiply the numerator and the denominator of the expression by: (4) * (3).
We have then:
(((4) * (3)) * ((x / 3) - (y / 4))) / (((4) * (3)) * ((x / 4) + (y / 3)) )
We now rewrite the expression:
(4x - 3y) / (3x + 4y)
The simplified expression is:
(4x - 3y) / (3x + 4y)
Answer:
The radius is 2 or The simplified radius is 4 ( if needed).
Step-by-step explanation:
- The equation of a circle is:
where the center is
, the point as
and the radius
.
-Put both the center and the point onto that equation:
![(0-2)^2+(1-1)^2=r^2](https://tex.z-dn.net/?f=%280-2%29%5E2%2B%281-1%29%5E2%3Dr%5E2)
-Then, solve them up:
![(0-2)^2+(1-1)^2 =r^2](https://tex.z-dn.net/?f=%280-2%29%5E2%2B%281-1%29%5E2%20%3Dr%5E2)
![(-2)^2+0=r^2](https://tex.z-dn.net/?f=%28-2%29%5E2%2B0%3Dr%5E2)
![4 + 0=r^2](https://tex.z-dn.net/?f=4%20%2B%200%3Dr%5E2)
![4 = r^2](https://tex.z-dn.net/?f=4%20%3D%20r%5E2)
![\sqrt{4} =\sqrt{r^2}](https://tex.z-dn.net/?f=%5Csqrt%7B4%7D%20%3D%5Csqrt%7Br%5E2%7D)
