Answer:

40 minutes

Step-by-step explanation:

Last year she ran five miles in 50 minutes

This year her timing improved by 20%. This means she runs 5 miles in 20% less time than last year

How long does it take her to run five miles?

= 50 minutes - 20% of 50 minutes

= 50 minutes - 20/100 * 50 minutes

= 50 minutes - 0.2 * 50 minutes

= 50 minutes - 10 minutes

= 40 minutes

This year, it takes her 40 minutes to run 5 miles

Answer:

⇒Store i charges $4 for one-time membership fee and a fee of $1.50 per rented DVD

⇒Store ii charges $5 for one-time membership fee and a fee of $2 per rented DVD

⇒ Renting a DVD in shop {i} is cheaper than in shop {ii}

Step-by-step explanation:

In the first store, the equation for cost can be calculated as;

Find slope using the data set

Number of DVDs rented               Cost {$}

1                                                        5.50

2                                                        7.0

3                                                         8.50

m= Δy/Δx

m= 8.50 - 5.50 / 3-1

m= 3/2 = 1.5

Write the equation

m= Δy/Δx

1.5 = y-7/ x-2

1.5 { x-2 } = y-7

1.5 x - 3.0 = y-7

1.5x -3.0 + 7 = y

1.5 x + 4= y

C= 4 + 1.5 d  ------where d is the number of DVDs rented

Comparing the two equations that model the cost of renting DVDs

i) C= 4 + 1.5d

ii) C=5 + 2d

⇒Store i charges $4 for one-time membership fee and a fee of $1.50 per rented DVD

⇒Store ii charges $5 for one-time membership fee and a fee of $2 per rented DVD

For example 2 DVDs are rented in both store, you can find the store which is cheaper as;

i) C= 4 + 1.5d  = 4+ 1.5*2 = 4 + 3 = $7

ii) C=5 + 2d = 5 + 2 * 2 = 5 + 4 = $9

⇒ Renting a DVD in shop {i} is cheaper than in shop {ii}

   Renting a DVD from store (2) is costlier than renting from store (2).

         y = mx + b

         Here, m = slope of the line

         b = y-intercept

For store (1),

Let the linear equation representing the cost for renting the DVDs is,

C = md + b

Here, m = slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

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

And 'd' = Number of DVDs

Let the two points lying on the line are (1, 5.5) and (2, 7),

So the slope will be,

[tex]m=\frac{7-5.5}{2-1}=1.5[/tex]

Equation of the line will be → C = 1.5d + b

Since, this line passes through a third point (3, 8.5),

Substitute the values in the equation of the line,

8.5 = 1.5(3)+ b

8.5 - 4.5 = b

b = 4

Hence, equation of the line for the cost of renting a DVD from store (1) will be,

C = 1.5d + 4 ---------(1)

For store (2),

Equation of the line has been given as,

C = 2d + 5 ------(2)

Equation (1) represents a fixed cost of $4 and $1.5 for renting each DVD.

Equation (2) represents a fixed cost of $5 and $2 for renting each DVD.

If Donnie rents a DVD from both the stores,

Cost for renting DVDs at store (1) → C = 1.5(1) + 4 = $5.5

Cost for renting one DVD at store (2) → C = 2(1) + 5 = $7

      Therefore, renting a DVD from store (2) is costlier than renting from store (2).

Answer:

(4,4)

Step-by-step explanation:

The intersection point of 10y-11x=-4 and -2y+3x=4 is (4,4) on a graph.

As per linear equation, the solution of the given system of equations is x = 4, y = 4.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

Given system of linear equation is:

10y - 11x = - 4 ......(1)

- 2y + 3x = 4​ ......(2)

Multiplying the equation (1) by 1 and Multiplying the equation (2) by 5 and then add both equations, we get:

   10y - 11x = - 4

+  (- 10y) + 15x = 20

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

    4x = 16

⇒ x = 4

Now, substituting the value of 'x' in the equation (2), we get:

- 2y + 3(4) = 4

⇒ - 2y + 12 = 4

⇒ - 2y = 4 - 12

⇒ - 2y = - 8

⇒ y = 4

Therefore, the solution of the given system of equations is x = 4, y = 4.

Answer:

(0,-8)

x=0

y=-8

Step-by-step explanation:

There are a couple of ways you can solve this I used what I think is called the elimination method

We first start by writing the equations in linear form (y=mx+b)

For the first one we have -12x-5y=40

we add 5y to both sides and subtract 40 to get

-12x-40=5y

divide by 5 to get

-12/5x-8=y

Then the second one we have

12x-11y=88

same deal here, add 11y and subtract 88 to get

12x-88=11y

divide by 11 and get

12/11x-8=y

We then set the two equations equal to each other and get

-12/5x-8=12/11x-8

We can add 8 to both sides and get

-12/5x=12/11x

Just by looking at it you can see that the only solution for x is 0

Plug in 0 to the first equation and get -12*0-5y=40

This means that -5y=40

Solve for y and get -8

Answer:

x=0 , y= -8

Answer:

45

Step-by-step explanation:

The points on the graph :

(4, 180) ; (7, 135)

x1 = 4 ; y1 = 180

x2 = 7 ; y2 = 315

The number of soda bottles the machine can make in a minute is the gradient or slope :

Gradient = change in y / change in x

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

Gradient = (315 - 180) / (7 - 4)

Gradient = 135 / 3

Gradient = 45

Hence, the machine can make 45 soda bottles in a minute.
