Can anyone help me with this question? Thanks!

Answers

Answer is n=8.

Step by step:

1) Add 1 on both sides (To isolate the variable, n)

-40 = -5n

2) Divide both sides by -5

-40/-5 = n

3) 2 negatives makes a positive and 40/5 is 8 so n is equal to 8

n=8

Answer:

n=8

Step-by-step explanation:

1. rearrange terms

-41 = - 1 - 5n

-41 = -5n - 1

2. add 1 to both sides of the equation

-41=-5n-1

-41+1=-5n-1+1

3.simplify

a.add the numbers

-41+1=-5n-1+1

-40=-5n-1+1

b. add the numbers

-40=-5n-1+1

-40=-5n

4. Divide both sides of the equation by the same term

-40=-5n

-40/-5=-5n/-5

5. simplify

a. divide the numbers

-40/-5=-5n/-5

8=-5n/-5

b. cancel terms that are both in the numerator and denominator

u=-5n/-5

8=n

c. move the variable to the left

8=n

Answers

Answer:

B. 15 edges

Step-by-step explanation:

According  to Euler's formula:

F + V = E + 2, where F- faces, V- vertices, E- edges

Substitute known values and solve for E:

(4 + 3 + 1) + 9 = E + 217 = E + 2E = 17 - 2E = 15

How long would it take for a deposit to double if the annual interest rate is 5%?
Show your work

Answers

Answer is 14.4 years

Step-by-step explanation:-

Given-

Annual interest rate = 5%

By using the rule of 72,

Rate x Time = 72

Rate = 5%

t = ?

So,

5 x t = 72

5t = 72

Isolate t by dividing both sides by 5 :-

→ 5t/5 = 72/5

→ t = 14.4 years

Hence, it will take 14.4 years for the deposit to double at 5% annual rate.

According to the question

A newspaper reports the following changes in the temperature of a city over 4 days:

write the equation of the line in slope intercept form if its slope is 3 and y intercept is -5
If you answer correctly I will give brainliest.

Answers

Answer:

y = 3x - 5

Step-by-step explanation:

1. The slope-intercept form a line is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Given the values of m and b, let's plug them in:

[tex]y = (3)x+(-5)[/tex] [tex]y = 3x-5[/tex]

Therefore, the equation of the line in slope-intercept form is y = 3x - 5.

Have a lovely rest of your day/night.

The equation of the line in slope intercept form is y=3x-5.

Given that, slope is 3 and y intercept is -5.

What is the slope intercept form?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as: y = mx + b.

Put m=3 and b=-5 in y = mx + b and simplify.

That is, y=3x-5

Therefore, the equation of the line in slope intercept form is y=3x-5.
