Answers

Answer:

-23

Step-by-step explanation:

rearrange to point slope form first

slope can be fine by y2-y1/x2-x1 (im using the first 2 points)

so 13-25 = -12 and -54-(-72) = 18, and the slope is -12/18 which is -2/3

then you can use any point (i used the first point) to create the point slope form which is y-ypoint=slope(x-xpoint) and equation would be y-25=-2/3(x+72)

turn it into slope intercept form by multiplying -2/3 within the equation and adding -25 on both sides

you will get y= -2/3x-23

and the y intercept will be (0, -23)

(o,-23)
This is because the slope is -2/3 and if you graph this it’ll show that the line crosses the y intercept at -23

Three out of five people surveyed said that Shrek 2 is better than Shrek 3 and Shrek 4. If a total of 560 people are surveyed, how many would you expect to agree that Shrek 2 is better?

Answers

Answer:

Shrek 2 IS better than the other 2 because THE OTHER TWO HAS NO PLOT!!

Answer:

336

Step-by-step explanation:

To find the answer, we will cross multiply.

3         ?

5       560

We will first multiply 3*560.

= 1680

Next, we will divide our previous answer by 5.

1680/5= 336

therefore, you would expect 336/560 people to like Shrek 2 better than 3 and 4.

take the 346 add 126 thousand to it equaling a good 472 thousand divide 126 thousand by 10 cause it is a ten year span that equals you get 12.6 thousand.

I need brainliest please

We want to find the rate of change of the population of Austin, Texas in the years between 1980 and 1990.

The answer is: r = 12,600 people/year.

We will assume that this increase in population is modeled with a linear equation, remember that a general linear equation is:

y = a*x + b

Where the rate of change, or slope, is a.

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope is given by the formula:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For this case we have two points, these are:

(1980, 346,000)

(1990, 472,000)

Then the slope or rate of change is just:

[tex]a = \frac{472,000 - 346,000}{1990 - 1980} = 12,600[/tex]

To be complete we need to add the correspondent units, which are people per year.

Then the rate of change is:

r = 12,600 people/year.
