Answer:

\boxed{(1, -3)}

Step-by-step explanation:

y+3=2 (x-1)

Put equation in slope-intercept form.

y=mx+b

y=2(x-1)-3

y=2x-2-3

y=2x-5

Let x = 1

y=2(1)-5

y=2-5

y=-3

The point (1, -3) lies on the line.

How to simplify this expression ?
Musya8 [376]

Answer:

\large \boxed{\sf \ \ \dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{2x+1}{x^2(x+1)} \ \ }

Step-by-step explanation:

Hello,

This is the same method as computing for instance:

\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{3+2}{2*3}=\dfrac{5}{6}

We need to find the same denominator.

Let's do it !

For any x real different from 0, we can write:

\dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{1}{x^2}+\dfrac{1}{x(x+1)}\\\\=\dfrac{x+1+x}{x^2(x+1)}=\dfrac{2x+1}{x^2(x+1)}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The Ratio of two numbers is 3/5, and their sum is 104. What are the 2 numbers?
Rom4ik [11]

Answer:

39 and 65

Step-by-step explanation:

the ratio of the two numbers is 3 : 5

sum the parts of the ratio, 3 + 5 = 8 parts

divide the sum by 8 to find the value of one part of the ratio

104 ÷ 8 = 13 ← value of 1 part of the ratio , then

3 parts = 3 × 13 = 39

5 parts = 5 × 13 = 65

the two numbers are 39 and 65
