Find the sum of the terms.

kow [346]

Answer:

Step-by-step explanation:

Given

$\frac{x}{x^2+3x+2}$ + $\frac{3}{x+1}$ ← factor the denominator of first fraction

= $\frac{x}{(x+1)(x+2)}$ + $\frac{3}{x+1}$

Multiply the numerator/ denominator of second fraction by (x + 2)

= $\frac{x}{(x+1)(x+2)}$ + $\frac{3(x+2)}{(x+1)(x+2)}$

The denominators are now common, so add the numerators leaving the denominator, that is

= $\frac{x+3x+6}{(x+1)(x+2)}$

= $\frac{4x+6}{(x+1)(x+2)}$ → with numerator 4x + 6 → C

Select the correct answer.

asambeis [7]

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

$y = mx + b$

where m=3 is the slope .

We substitute the slope to get:

$y = 3x + b$

We substitute the point to find b.

$- 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4$

The equation of the straight line is:

$y = 3x + 4$

Misha Larkins [42]

Answer:

6p + 8b

Let us assume that p would be the number of cups in each pack

And b would be the number of cups in boxes

Given that

There are 6 cups in each pack

And, 8 cups in each box

So the totla number of cups in each pack be 6p

And, the total number of cups in each box is 8b

Now the total number of cups did Alision buys is 6p + 8b
