Using the concept of unit rate we calculate the cost of mowing 6 laws as $150 .

Rates and ratios frequently vary with regard to time, geography, a particular object (or group of objects), etc. They are typically mathematical functions as a result.

The charge to mow one lawn is $25 . This is the unite rate of the lawn.

Therefore the charge for 6 lawns is  = $25 × 6 = $150

Hence the cost to mow 5 lawns is $150.

The required equation that is perpendicular to the line y = -¾ x - 14 and goes through the point (0, 13) is 3x + 4y = 52 .

Given equation is y = - 3/4 - 14

this is of the form y = mx + c

on comparing, m= - 3/4

And the points given are x = 0 and y =13

thus as we know that the equation of the line is

y - y₁ = m ( x- x₁ )

On substituting the values mentioned above we see that

y - 13 = - 3/ 4 ( x - 0 )

4 y - 52 = - 3 x

and on rearranging we get :

3x + 4y = 52

Thus the required equation that is perpendicular to the line y = -¾ x - 14 and goes through the point (0, 13) is 3x + 4y = 52 .

To find the set of a quadratic inequation, we first need to find the roots of the quatradic equation. The roots can be found by using the same inequality but changing the inequality sign the euqal sign:

Let's use the Bharkara Equation to find the roots:

So we get the roots x = 3 and x = -5. This are the point at which the graph changes its sign.

The quadratic term (the one multiplying x²) is 1, which is positive. Because of that, the parabola of the quadratic expression has a minimum vertex:

For the drawing, it can be seen that when x is between -5 and 3, the equation has a negative sign, while when x is lower than -5 or greater than 3 the expression has positive sign. We want the expression:

So, when it is greater than 0, meaning positive. Then, the set that solves the quadratic inequation is:

Answer: -3

Step-by-step explanation:

The slope can be calculated by the equation

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

So choosing any two points, we can find the slope.

I'll chose (0,3) and (2,-3).

-3 - 3 = -6

2 - 0 = 2

So, the slope is -6/2 which simplifies to -3.

The inequality will be written as 40x + 20 < 280.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that a group of friends wants to go to the amusement park. They have no more than $280 to spend on parking and admission. Parking is $20, and tickets cost $40 per person, including tax.

The inequality will be written as:-

40x + 20 < 280.

If Keilantra will make a guaranteed wage of $40 and she will get about $14 in tips for each table she waits on,

Part 1

If Keilantra waits on 17 tables, the she will earn $278

Part 2

If Keilantra waits on t tables, the she will earn 40+14t

The guaranteed wage she earn = $40

The amount she earn for each table she waits as tip = $14

Part 1

The number of table she waits on = 17 tables

Then the amount she earn in a day = The guaranteed wage she earn +The amount she earn for each table she waits as tip × The number of table she waits on

= 40+14×17

= 40+238

= $278

Part 2

The number of table she waits on = t tables

Then the amount she earn in a day = 40+14t

Hence, if Keilantra will make a guaranteed wage of $40 and she will get about $14 in tips for each table she waits on,

By solving the system of equations, and seeing in which quadrant is each solution, we conclude that:

Here we get the following system of equations:

x^2 - y = 7

y - 5x = -11

If we isolate the same variable in both of the equations, then we can equate them, so I will isolate "y" in both of the equations of the system.

y = x^2 - 7

y = -11 + 5x

Now we can write:

x^2 - 7 = -11 + 5x

So we have the quadratic equation, this can be rewritten as:

x^2 - 7 + 11 - 5x = 0

x^2 - 5x + 4 = 0

Using the Baskhara's formula (or the quadratic formula), we will get the two solutions for x.

[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*(4)} }{2*1}[/tex]

The solutions are:

[tex]x = \frac{5 \pm \sqrt{(9} }{2} \\\\x = \frac{5 \pm 3}{2}[/tex]

So we get:

x = (5 + 3)/2 = 4

x = (5 - 3)/2 = 1

Evaluating the linear equation in these values of x:

y = -11 + 5*4 = -11 + 20 = 9

y = -11 + 5*1 = -6

So we get the coordinate pairs (4, 9) which is on the first quadrant because both values are positive, and (1, -6) which is on the fourth quadrant because the x-value is positive and the y-value is negative.

The area ratio is 100:49.

The ratio of areas equals the ratio of squares of matching sides.

Let's put this fraction of comparable ratios into an equation and then input in our two known values to get our two unknown values:

The ratio of two identical figures areas is equal to the square of the ratio of their corresponding sides.

For instance, if the ratio of the respective widths of two comparable rectangles is 2:3, the ratio of their areas is

The solution for the system of linear equations y = 5 − x and 4x + 2y = 10 are x = 0 and y = 5

Linear equations are equations that have constant average rates of change.

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

y = 5 − x

4x + 2y = 10

Substitute y = 5 − x in the equation 4x + 2y = 10

So, we have the following equation

4x + 2(5 - x) = 10

Open the brackets

4x + 10 - 2x = 10

Evaluate the like terms

2x = 0

Divide through by 0

So, we have

x = 0

Substitute x = 0 in y = 5 - x

y = 5 - 0

Step-by-step explanation:

The perimeter of a square having area of 36[tex]cm^{2}[/tex] is equal to 24cm

Square of area A= 36[tex]cm^{2}[/tex]

We know that a square is a quadrilateral( a closed figure with four sides) with all 4 sides equal in length. Let the measure of one side of a square be x. from the formula to find out the area of a square we know that

Area of a square A = [tex]x^{2}[/tex]

∴From the data given in the problem

[tex]x^{2}[/tex] = 36

⇒x = √36

⇒x = 6

∴The measure of one side of a square = x cm = 6 cm

We know that the perimeter of a square = x+x+x+x = 4x

∴The perimeter of the given square = 4x = 4 × 6 = 24cm

Hence we get by solving as done above that for a square of area 36cm^2

the perimeter of the square is 24cm

Answer:

B

Step-by-step explanation:

I cannot see option D but regardless, C is a function for the following reasons

A function y = f(x) is a relationship in x such that f(x)  has only 1 value for a value of x.

In A, we see that for x = -1 we have y = 2 and y = 4 for a single value of x = -1

That alone is sufficient to dismiss this as a function. If that wasn't bad enough you see that y = -3 and -4 for x = 2

In C we see the same problem
For x = 5 there are two value of y = -3 and -2
So we can disregard C

In B we can see a definite pattern
Between x = -2 and x = 0 we see that y increases by 1 unit for every increase of 1 unit in x. This is a linear relationship with a slope of + 1

Between x = 0 and x = +2, for every increase of 1 unit in the x-value, the y-value decreases by 1 unit. This is also a linear relationship but with a slope of -1

In particular this is what is known as a piecewise function. Its function expression is different for different intervals of x value

It can be expressed as follows
f(x) =    x + 2 for -2 ≤ x ≤ 0
     =   -x + 2  for 0 ≤ x ≤ 2

Now, we will take some first numbers in some math sums to be 5, 6 and 7.

Now, the second digit can be found easily by subtracting the numbers from 13.

So, the digits should be less than the result we get.
