If you triple 4 and subtract 2 each day how many days until you have zero

Answers

If you triple 4 you get 12, subtract 2 every day and in 6 days you will get to 0.

4 x 3 = 12
12 - 2 x 6 = 0

It takes 3 days until the value becomes zero when you triple 4 and subtract 2 each day.

Let "d" be the number of days, and "x" be the value at the end of each day.

On the first day, "x" starts at 4, and then it's reduced by 2 each day. So, the value at the end of each day can be represented as:

Day 1: x = 4

Day 2: x = 4 - 2 = 2

Day 3: x = 2 - 2 = 0

As we can see, on Day 3, the value becomes zero.

Therefore, it takes 3 days until the value becomes zero when you triple 4 and subtract 2 each day.

What is the equation of the line that passes through the point (3,-5) and has a
slope of o?

Answers

Answer:

y = -5

Step-by-step explanation:

slope of 0 means m = 0 in y intercept form y = mx + b.

they have given you (3, -5), plug these in and solve for your equation.

remember, a line that has a 0 slope means it is a horizontal line.

y = mx + b

-5 = 0(3) + b

-5 = b

so you have, y = -5.
