Answer:

[tex] y = -\dfrac{4}{5}x + 11 [/tex]

Step-by-step explanation:

(5, 7), (10, 3)

[tex] m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{3 - 7}{10 - 5} = -\dfrac{4}{5} [/tex]

[tex] y = mx + b [/tex]

[tex] y = -\dfrac{4}{5}x + b [/tex]

[tex] 7 = -\dfrac{4}{5} \times 5 + b [/tex]

[tex] 7 = -4 + b [/tex]

[tex] b = 11 [/tex]

Answer:

[tex] y = -\dfrac{4}{5}x + 11 [/tex]

Answer:

Three are 27 rows of saplings

Step-by-step explanation:

Since 21 saplings were left out of 750 saplings, the number of saplings arranged will be 750 -21 = 729 saplings

We were told that the number of saplings arranged per row is equal the number of rows

So let’s say the number of saplings arranged per row is x

Automatically, the number of rows too will be x

So the total number of saplings arranged will be;

x * x = x^2

This is equal to 729

x^2 = 729

x^2 = 27^2

Since power is equal, equate the base

This means that x = 27

Answer:

48 feet

Step-by-step explanation:

6 feet wide

3 times as long as it's wide (width) = 6×3 = 18

18 + 6 + 18 + 6

= 24 + 24

= 48 feet

Answer:

5-1=4 and 5+4=9

Step-by-step explanation:

[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]

System of Linear Equations entered :

[1] x - y = 4

[2] x + y = 9

Graphic Representation of the Equations :

y + x = 4 y + x = 9

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = -x + 9

// Plug this in for variable y in equation [1]

[1] x - (-x +9) = 4

[1] 2x = 13

// Solve equation [1] for the variable x

[1] 2x = 13

[1] x = 13/2

// By now we know this much :

x = 13/2 y = -x+9

// Use the x value to solve for y

y = -(13/2)+9 = 5/2

Solution :

{x,y} = {13/2,5/2}

Answer:

It takes 31 Pounds for UPS and FedEx to cost the same?

Step-by-step explanation:

The equation for the cost of a UPS shipping:

7 + .20x

to check the answer, you can do : 7 + (.20 x 31)

= $14.00

The cost for the cost of the PedEx shipping is:

5 + .30x

to check the answer, you can do : 5x + (.30 x 31)

= $14.00

Step-by-step explanation:

Wow! There are 2 things going on here, so let's go step by step.

The first thing to notice is that the numbers are going negative, positive, negative, positive. Odd-numbered terms are negative while even-numbered terms are positive. Since 9 is odd number, we know the answer must be negative.

Secondly, the 1, 4, 9, 16 sequence is called the square numbers. They are 1 x 1, 2 x 2, 3 x 3, 4 x 4, etc. The 9th term will be 9 x 9 ( ignoring the negative).

Adding the first point with the second, we get   (-81)  { negative eighty-one }

Hope this helps.

Answer:

It costs $795

Step-by-step explanation:

$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

Answer:

f=x-9

Step-by-step explanation:

Answer:

f(x) = 10

Step-by-step explanation:

f(x)=9-x   f(-1)

Put in the -1 for x

f(x) = 9 - (-1)

f(x) = 9 + 1

f(x) = 10

Answer:

The payment for driving 80 miles is $78

Step-by-step explanation:

Mathematical model

Mathematical models are used in disciplines like natural sciences and engineering, among many others.

The data provided in the question allows building a model for the charges of the car rental, knowing there are two fees:

A fixed charge of $50

A variable charge or $0.35 per mile driven.

Part A

Using m as the number of miles driven for the day, the model for the payment for the car rental is:

P(m)=50+0.35m

Part B

Find the payment if the car is driven m=80 miles:

P(80)=50+0.35*80

P(80)=50+28=78

The payment for driving 80 miles is $78

Step-by-step explanation:

i know this is late but on the diagram all the angles across from each other count as a vertical angle and i took the assignment and got it rigth

4 pairs of vertical angles are there in the diagram.

Two lines intersects each other, then the angles formed is opposite to each other are called vertical angles.

4 lines intersect to form 14 angles.

The diagram is attached below for reference.

Angles 14 and 12, 11 and 13, 10 and 8, and 7 and 9 are vertical angles.

There are 4 pairs of vertical angles are here.

Hence, 4 pairs of vertical angles are there in the diagram.

Answer:

B

Step-by-step explanation:

Mathematically, we shall be using the z-score here

Z-score = (x-mean)/SD

From the question, mean = 80 and SD = 4

So we want to get the option in the question that has a z-score of 1 or below

Let’s look at 75

80-75 = 5 ( this is clearly above 1 standard deviation of 4)

For 77;

80 -77 = 3

This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean

Option B) is correct.

Step-by-step explanation:

Given :

Mean [tex](\mu)[/tex]  = 80

Standard Deviation [tex](\sigma)[/tex]  = 4

Calculation :

We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]

[tex]\mu-\sigma = 80-4=76[/tex]

[tex]\mu+\sigma =80+4=84[/tex]

The interval is (76,84)

Therefore, option B) is correct.
