Find the slope between the points: (3,4) and (-1,-2)

Answer:

y=2x+1

Step-by-step explanation:

Input X=2 into the function, so y=2(2)+1, which is 5. This matches the table.

Answer:

It's the first one: y= 2x +1

Step-by-step explanation:

Answer:

(-5)

Step-by-step explanation:

Using PEMDAS you should do (-5) because Parenthisis Always Go First, since their are two parenthisis go left to right and answer those first. after that do (3) and after that simply go left to right with 6+10-(-5)(3)-5. Hope this helps.

Step-by-step explanation:

Answer:  [tex]\dfrac{1}{10}[/tex]

Step-by-step explanation:

Given: The bag has 5 green chips, 3 red chips, and 7 blue chips.

Total chips = 5+3+7= 15

Number of ways to select a red and then a blue chip = 3 x 7 = 21

Total number of ways to select 2 chips without replacement = 15 x 14 =210

Required probability = [tex]\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]=\dfrac{21}{210}=\dfrac{1}{10}[/tex]

So, the probability that he selects a red and then a blue chip (without replacing) =  [tex]\dfrac{1}{10}[/tex]

Answer:

All but the second one

Step-by-step explanation:

Find the inverse of each function:

b(x)=x^2+3

y=x^2+3

x=y^2+3

x-3=y^2

sqrt(x-3)=y

This inverse function is a function

d(x)=-9

y=-9

This doesn't have an inverse function

m(x)=-7x

y=-7x

x=-7y

-1/7x=y

This inverse function is a function

p(x)=|x|

y=|x|

x=|y|

x=y

This inverse function is a function

Therefore, all but the second function have inverses that are functions

Answer:

All but the second one have inverse functions

Answer:

4 bottles of Water

Step-by-step explanation:

First, we need to find how much each water costs. So, I created this equation below.

9/12=?

The answer to the equation is .75, or 75 cents.

So, we can now make yet another equation to find the amount to buy with 3 dollars.

3/.75=?

The answer to that equation is 4.

Thus, the answer is 4 bottles of water.

Answer:

the answer is:

5x - 2x = 15 - 6

3x = 9

x = 3

============================================================

Explanation:

Let's find the slope of the table. This will tell us the rate of change.

m = slope

m = (y2-y1)/(x2-x1)

m = (25250 - 26375)/(2 - 1) .... I used the first two rows

m = -1125/1

m = -1125

The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.

Since we're told the initial altitude was 27500 ft, this means b = 27500

This means y = mx+b turns into y = -1125x+27500

x is the number of minutes and y is the altitude at time x

As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.

------------------

Now plug in y = 16250 and solve for x

y = -1125x+27500

16250 = -1125x+27500

-1125x+27500 = 16250

-1125x = 16250-27500

-1125x = -11250

x = -11250/(-1125)

x = 10

It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.

Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.

Answer:

$0.75

Step-by-step explanation:

Given that a pack of 6 Gatorades costs 4.50, simply divide 4.50 by 6.

4.50/6=0.75

Thus, $0.75 is your answer.

Answer:

$26.85

Step-by-step explanation:

53.70÷2= 26.85

Answer:   1.50+5m=76.50 m=15

Step-by-step explanation:

The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

pick-up fee = $1.50 plus $5 per mile

Since, m is the number of miles in the taxi ride

So, equation for pick-up fee for m miles,

pick-up fee = $1.50 + $5m

Now total fare = $76,50

Thus, required equation to determine m is given as,

1.50 + 5m = 76.50

Subtracting 1.5 both the side we get,

1.50 + 5m - 1.5 = 76.50 - 1.5

⇒ 5m = 75

or, m = 75/5

⇒ m = 15

Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.
