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.
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.

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
n=8
How long would it take for a deposit to double if the annual interest rate is 5%?
Show your work
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.
