Answer:
13/15
Step-by-step explanation:
2/3 + 1/5
You first,
- Find the L. C. M, i hope u know the full name, if u don't, let me know in the comment section.
- the L. C. M is 15
- therefore it will be 10+3/15
- 13/15
Answer:
![x=\frac{1}{a-b}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7Ba-b%7D)
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Step-by-step explanation:
The given expression is ![ax-bx+1](https://tex.z-dn.net/?f=ax-bx%2B1)
We factor the left hand side to get:
![(a-b)x=1](https://tex.z-dn.net/?f=%28a-b%29x%3D1)
We divide both sides by: a-b
![x=\frac{1}{a-b}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7Ba-b%7D)
Observe that the difference of a and b is in the denominator.
The whole is of the form: ![x\propto \frac{1}{a-b}](https://tex.z-dn.net/?f=x%5Cpropto%20%5Cfrac%7B1%7D%7Ba-b%7D)
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Answer:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
