The expression shown below describes a sequence of numbers HELP ME

Mathematics
1 answer:
julsineya [31]3 years ago
6 0

Answer:

B

Step-by-step explanation:

Given the expression

2n + 3

To determine the terms in the sequence generated by this expression

Substitute n = 1, 2, 3, 4, ... into it

a₁ = (2 × 1) + 3 = 2 + 3 = 5

a₂ = (2 × 2) + 3 = 4 + 3 = 7

a₃ = (2 × 3) + 3 = 6 + 3 = 9

a₄ = (2 × 4) + 3 = 8 + 3 = 11

a₅ = (2 × 5) + 3 = 10 + 3 = 13

The first 5 terms of the sequence are 5, 7, 9, 11, 13

Answer:

The slope is 24

Step-by-step explanation:

Use any two points in the graph to find the slope of the graph
- - - - - - - - - - - - - - - - - - - -
Step 1. Use two points

Ex: (10, 320) & (5, 200)

Step 2. Find the slope using the two points

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (200 - 320)/(5 - 10)

m = -120/-5

m = 120/5

m = 24

The slope of the graph/line is 24

Answer:

Step-by-step explanation:

\frac{5}{x-3}+\frac{2}{x+1}=3  \\\\\frac{5(x+1)+2(x-3)}{(x-3)(x+1)} =3\\\\5x+5+2x-6=3(x-3)(x+1)\\\\7x-1=3(x^2+x-3x-3)\\\\7x-1=3(x^2-2x-3)\\\\7x-1=3x^2-6x-9\\\\0=3x^2-6x-7x-9+1\\0=3x^2-13x-8

Hence proved!

Divide 25/11 by 5/22<br>​
Igoryamba

Answer:

25/11 divided by 5/22 = 10

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 11 on the left side and the dividend 25 on the right side like this:

           

 1 1 ⟌ 2 5  

Step 2:

The divisor (11) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

       0    

 1 1 ⟌ 2 5  

Step 3:

Multiply the divisor by the result in the previous step (11 x 0 = 0) and write that answer below the dividend.

       0    

 1 1 ⟌ 2 5  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

 1 1 ⟌ 2 5  

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (5) like this:

       0    

 1 1 ⟌ 2 5  

     - 0    

       2 5  

Step 6:

The divisor (11) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:

       0 2  

 1 1 ⟌ 2 5  

     - 0    

       2 5  

Step 7:

Multiply the divisor by the result in the previous step (11 x 2 = 22) and write that answer at the bottom:

       0 2  

 1 1 ⟌ 2 5  

     - 0    

       2 5  

      2 2  

Step 8:

Subtract the result in the previous step from the number written above it. (25 - 22 = 3) and write the answer at the bottom.

       0 2  

 1 1 ⟌ 2 5  

     - 0    

       2 5  

     - 2 2  

         3  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 25 divided by 11 calculated using Long Division is:
