Step-by-step explanation:

A linear equation is in the form of: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

m is the slope and it's given, which is -6

b is the y-intercept and it's given, which is 9

When we plug in to the form we get:

[tex]y=-6x+9[/tex]

Answer:

y =-2x+7

Step-by-step explanation:

Hello : let  A(2,3)    B(1,5)

the slope is :   (YB - YA)/(XB -XA)

(5-3)/(1-2)  = 2/-1 =-2

an equation is : y=ax+b     a is a slope

y = -2x +b

the line through point  (2,3) :  3 = (-2)(2)+b

Answer:

x ≤ 10.3 people

Approximately x ≤ 10 people

Step-by-step explanation:

Parking = $17.50

Tickets = $25 per person

Let

x = number of people who can go to the amusement park.

17.50 + 25x ≤ 275

25x ≤ 275 - 17.50

25x ≤ 257.50

x ≤ 257.50/25

x ≤ 10.3

Approximately 10 people can to the amusement park

Answer:

H = -52t + 6455

Step-by-step explanation:

2014 is 14 years since 2000. That gives you the point (14, 5727).

2017 is 17 years since 2000. That gives you the point (17, 5571).

Since we have two points in the line, we can find the equation of the line.

y = mx + b

m = slope = (difference in y)/(difference in x)

m = (5571 - 5727)/(17 - 14) = -156/3 = -52

y = -52x + b

Now we use one of the points for x and y, and we solve for b.

5727 = -52(14) + b

b = 6455

The equation is

y = -52x + 6455

Using H and t, we have

H = -52t + 6455

The relationship between the number of hospitals and the years, is a linear function.

The equation for the number of hospitals is: [tex]H = -52t + 6455[/tex]

Let

[tex]t \to[/tex] years since 2000

[tex]H \to[/tex] number of hospitals since 2000

So, we have:

[tex](t_1,H_1) = (14,5727)[/tex] ---- 2014

[tex](t_2,H_2) = (17,5571)[/tex]

Calculate the slope (m)

[tex]m = \frac{H_2 - H_1}{t_2 - t_1}[/tex]

This gives:

[tex]m = \frac{5571 - 5727}{17-14}[/tex]

[tex]m = \frac{-156}{3}[/tex]

[tex]m = -52[/tex]

The linear equation is then calculated using:

[tex]H = m(t - t_1) + H_1[/tex]

So, we have:

[tex]H = -52(t - 14) + 5727[/tex]

[tex]H = -52t + 728 + 5727[/tex]

[tex]H = -52t + 6455[/tex]

Hence, the equation H is: [tex]H = -52t + 6455[/tex]

Answer:

9 and 4

Step-by-step explanation:

Answer:

Perimeter is equal to all four sides added together.

Length = 3W; L=3W

So

P = 2(W) + 2(L)  substitute the equation for length above you get

P = 2(W) + 2(3W)  and combine

P = 2W + 6W = 8W; put in what the perimeter is and solve for W

66 = 8W, so W = 8.25

W = 8.25, L = 24.75

Answer:

2) x = -3

Step-by-step explanation:

Collect like terms, so gather all your x's on one side, and numbers in the other.  Add -6x and +15 to both sides, so you get -2x - 6x = +9 + 15, so we have -8x = 24, divide both sides by -8 you get x = -3.

Answer:

177

Step-by-step explanation:

If the top 5 performers are not considered, the average drops by 2.

Thus,average without top 5 performers = 85 - 2 = 83

Total scored with 5 table toppers = 52 × 85 = 4420

Total scored without 5 table toppers = 47 × 83 = 3901

Total scores of top 5 table toppers = 4420 - 3901 = 519

We are told that each of the 5 top scorers had distinct integral scores.

Also, all of them will score greater than 83.

Thus,possible maximum score of table topper = 519 - (84 + 85 + 86 + 87) = 177

Answer:

900

Step-by-step explanation:

The area of the final triangle would be 900 cm².

Scale factor is used to compare the final and initial dimensions of the figure. Mathematically, we can write scale factor -

{K} = {final dimensions/initial dimensions}

Given is that a triangle has an area of 36 cm². The base and height are scaled by a factor of 5.

Assume the initial dimensions of the triangle be {x} and {y} respectively. So, we can write the initial area as -

{1/2}{x}{y} = 36

{x}{y} = 72

After the scaling, we can write the final area as -

A = {1/2}{5x}{5y}

A = {25/2}{x}{y}

A = 12.5 x 72

A = 900 cm²

Therefore, the area of the final triangle would be 900 cm².

Answer:

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

Step-by-step explanation:

Diagonal of a square:

The diagonal of a square is found applying the Pythagorean Theorem.

The diagonal of the square is the hypothenuse, while we have two sides.

Diagonal of 12m:

This means that [tex]d = 12[/tex], side s. So

[tex]s^2 + s^2 = 12^2[/tex]

[tex]2s^2 = 144[/tex]

[tex]s^2 = \frac{144}{2}[/tex]

[tex]s^2 = 72[/tex]

[tex]s = \sqrt{72}[/tex]

Factoring 72:

Factoring 72 into prime factors, we have that:

72|2

36|2

18|2

9|3

3|3

1

So

[tex]72 = 2^{3}*3^{2}[/tex]

So, in simplest radical form:

[tex]s = \sqrt{72} = \sqrt{2^{3}*3^{2}} = \sqrt{2^3}*\sqrt{3^2} = 2\sqrt{2}*3 = 6\sqrt{2}[/tex]

Perimeter of the garden:

The perimeter of a square with side of s units is given by:

[tex]P = 4s[/tex]

In this question, since [tex]s = 6\sqrt{2}[/tex]

[tex]P = 4s = 4*6\sqrt{2} = 24\sqrt{2}[/tex]

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]
