Answer:

y>3x-1

Step-by-step explanation:

To write the inequality represented by the graph, let's first determine the equation of the line.

So, we can see that the line passes through the two points (0,-1) and (1,2).

With this, let's figure out the slope. The formula for slope is:

m=\frac{y_2-y_1}{x_2-x_1}

Let's let (0,-1) be (x₁ y₁) and let's let (1,2) be (x₂, y₂). So:

m=\frac{2-(-1)}{1-0}

Evaluate:

m=3/1=3

Therefore, the slope is 3.

We also know that the y-intercept is y=-1 from the point (0,-1).

So, we can use the slope-intercept form:

y=mx+b

Where m is the slope and b is the y-intercept.

Substitute 3 for m and -1 for b. So:

y=3x-1

Notice that the line is dotted. This means that we will <em>not</em> have "or equal to" for our inequality.

Now, note that the shaded region is <em>above</em> our line. Therefore, y must be <em>greater than</em> our equation. Therefore, our inequality would be:

y>3x-1

And we're done!

➷ Calculate the number of hours:

24 x 3 = 72

72/13 = 5.5....

This is 5 whole half lives

You have to half the value 5 times

149/2 = 74.5

74.5/2 = 37.25

37.25/2 = 18.625

18.625/2 = 9.3125

9.3125/2 = 4.65625

The closest value is B. 3.21 so that should be the answer

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

If it takes one person 4 hours to paint a room and another person 12 hours to
paint the same room, working together they could paint the room even quicker, it
turns out they would paint the room in 3 hours together. This can be reasoned by
the following logic, if the first person paints the room in 4 hours, she paints 14 of
the room each hour. If the second person takes 12 hours to paint the room, he
paints 1 of the room each hour. So together, each hour they paint 1 + 1 of the 12 4 12
room. Using a common denominator of 12 gives: 3 + 1 = 4 = 1. This means 12 12 12 3
each hour, working together they complete 13 of the room. If 13 is completed each hour, it follows that it will take 3 hours to complete the entire room.
This pattern is used to solve teamwork problems. If the first person does a job in A, a second person does a job in B, and together they can do a job in T (total). We can use the team work equation.
Teamwork Equation: A1 + B1 = T1
Often these problems will involve fractions. Rather than thinking of the first frac-
tion as A1 , it may be better to think of it as the reciprocal of A’s time.
World View Note: When the Egyptians, who were the first to work with frac- tions, wrote fractions, they were all unit fractions (numerator of one). They only used these type of fractions for about 2000 years! Some believe that this cumber- some style of using fractions was used for so long out of tradition, others believe the Egyptians had a way of thinking about and working with fractions that has been completely lost in history.

2, 10 after a dilation by a scale factor of 1/2 centered at the<br> origin?
anzhelika [568]

Answer:

  (1, 5)

Step-by-step explanation:

When the center is the origin, the dilation factor multiplies each coordinate:

  (2, 10) ⇒ (1/2)(2, 10) = (1, 5)
