For this case we have the following arithmetic sequence:

$a_ {n} = 15 + 5 (n-1)$

To write in function form, we apply distributive property to the terms within parentheses:

$f (n) = 15 + 5n-5$

Different signs are subtracted and the major sign is placed.

We simplify:

$f (n) = 5n + 10$

Answer:

$f (n) = 5n + 10$

Plz I need URGENT help!

Answer:

The average temperatures were:

New York City: 63
San Francisco: 64

Step-by-step explanation:

Remember that, the average is obtained in the form below:

Average = The sum of all the values / the number of values.

In this case, the number of values is 12 because are the number of months in the year. The sum of values is shown below for each case:

Average temperature in New York City = (39 + 42 + 50 + 61 + 71 + 81 + 85 + 84 + 76 + 65 + 55 + 47) / 12 = 63.
Average temperature in San Francisco = (57 + 60 + 62 + 63 + 64 + 67 + 67 + 68 + 70 + 69 + 63 + 58) / 12 = 64.

I don't add units because the table doesn't specify if they are Celsius, Fahrenheit, or others.

What is y=2x+24 y=-2x

Lemur [1.5K]

Answer:

x = -6, y = 12

Step-by-step explanation:

Equations:

y = 2x + 24

y = -2x

Bring the the equation together and add like terms together:

-2x = 2x + 24

-4x = 24

Divide both sides by -4 to isolate x:

$\frac{-4x}{-4} = \frac{24}{-4} \\\\x = -6$

Find y:

y = -2(-6)

y = 12

Verify:

12 =2(-6) + 12

I need those two step by step

Naddik [55]

Answer:

h= 1/4; g = 4

Step-by-step explanation:

1. 3/5h - 1/10 = h/5

First multiply by 10 to get rid of the fractions

(10)3/5h - (10)1/10 = (10)h/5

6h - 1 = 2h

Add one to each side

6h = 2h + 1

Subtract 2h from each side

6h - 2h = 1

4h = 1

Divide 4 by each side

h = 1/4

2. 3g - 10/4 = 1/2

Multiply each side by 4 to get rid of fractions

(4)3g - 10/4 = (4)1/2

3g - 10 = 2

Add 10 to each side

3g = 12

Divide each side by 3

g = 4
