If I was asked to think of a number and multiply it by 2, I could
write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, take away 1 and multiply the result by 3."
Please answer

Answers

Answer 1

you didn't say what number you would think of

Answer 2

I'm guessing this is multiple choice but the formatting of the question is a bit hard to understand.

write it algebraically as 2x

2x just means multiply x by 2

The algebraic equation for the other example is 3(x-1) which is 3x - 3

This is not multiplying by two, so it is wrong.

What is the slope and y-intercept of the equation 3x -y=3

Answers

Answer:

Slope = 3

Y Intercept = 3

Step-by-step explanation:

3x - y = 3

(subtract 3x from both sides - we have to get y by itself)

-y = -3x - 3

(divide by -1 from both side - we need to make y positive)

y = 3x + 3

What’s the distance 3 1/4 and -15

Answers

Answer:

18 1/4

Step-by-step explanation:

The easiest way to do this is to start at 0 and go 3 1/4 units to your right.

Then start at 0 and go -15 units to your left.  So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.

The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.

A formula would look like this

distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )

distance = sqrt( (3 1/4 -  - 15)^2 + (4 - 4)^2 )

distance = sqrt(  (18 1/4 )^2 + 0)

distance = 18 1/4

Step-by-step explanation:

Giving the following information:

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.

First, we need to calculate the reduction of the substance each year:

Yearly reduction= 8,000/400= 20 grams per year

Now, for 300 years:

300 year reduction= 20*300= 6,000

There are 2,000 grams left after 300 years.

What is the polygon?

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

here, we have,

An exterior angle is an angle between a side of a polygon and an extended side adjacent to it.

A polygon refers to any closed curve comprised of a set of connected sides such that no two sides cross.

Convex 55-gon means a convex polygon with  n sides.

The sum of measures of any polygon is equal to 360

So, the sum of the measures of the exterior angles of a convex 55-gon is equal to 360.
