**Answer:**

f(3) = 4(3)-2 = 12-2 = 10

**Step-by-step explanation:**

By comparing f(3) and f(x), you can see that it is basically replacing the x in the equation with the value of 3.

A quadrilateral has coordinates of (-4,3), (-3,8). (2,5), and (1, -7).

Enter the perimeter of this quadrilateral rounded to the nearest whole unit.

**Answer:**

The perimeter of a quadrilateral will be equal to the addition of the length of each side of the quadrilateral.

Here we only have the vertices of the quadrilateral, and to calculate the length of the sides, first we need to plot the points in a graph and see which pairs make the quadrilateral.

You can see the image below, where i did a rough sketch of the problem.

in the image, you can see that the sides of this rectangle are the ones formed by the pairs:

(-4,3) and (-2, 8)

(-2, 8) and (2, 5)

(2,5 ) and (1, -7)

(1, - 7) and (-4, 3)

Now let's calculate the length of each side.

Remember that when we have two points (a, b) and (c, d) the distance is:

D = √( (a - c)^2 + (b - d)^2)

Now we need to calculate four distances:

**(-4,3) and (-2, 8)**

D1 = √( (-4 + 2)^2 + (3 - 8)^2) = 5.39

**(-2, 8) and (2, 5)**

D2 = √( (-2 - 2)^2 + (8 - 5)^2) = 5

**(2,5 ) and (1, -7)**

D3 = √( (2 - 1)^2 + (5 + 7)^2) = 12.04

**(1, - 7) and (-4, 3)**

D4 = √( (1 +4)^2 + (-7 -3)^2) = 11.18

Now we add those four distances to get the perimeter:

P = 5.39 + 5 + 12.04 + 11.18 = 33.61

And we want to round it to the next whole number, because the first digit after the decimal point is larger than 5, we round up, and get:

p = 37

answer: $12

explanation:

we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.

this gives us the equations:

2x + 6y = 156

and

1x + 9y = 210

where x is CDs and y is DVDs

multiply the top equation by 9 and the bottom by -6 to solve for x:

18x + 54y = 1404

-6x - 54y = -1260

add from top to bottom:

12x = 144

divide both sides by 12 to get:

x= $12

explanation:

we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.

this gives us the equations:

2x + 6y = 156

where x is CDs and y is DVDs

multiply the top equation by 9 and the bottom by -6 to solve for x:

-6x - 54y = -1260

add from top to bottom:

12x = 144

The **points **are (-5,7) and (10,1). The slope of the points is -2/5.

Any two different points on a line can be used to calculate the slope of any line. The slope of a line formula is used to determine the ratio of "**vertical change**" to "**horizontal change**" between two different points on a line.

Given that,

The points are (-5,7) and (10,1).

We have to find the slope of the points.

The **relationship** between how a line's y coordinate changes and how its x coordinate changes determines a line's slope. y and x are the net changes in the y and x coordinates, respectively. As a result, the change in y coordinate with regard to the change in x coordinate can be written as,

**Slope** of the points=[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Here,

x₁=-5,

y₁=7

x₂=10

y₂=1

Slope of the points [tex]= \frac{1 - 7}{10 + 5}[/tex]

Slope of the points =(-6)/(15)

Slope of the points = -2/5

Jill is building a wooden raised bed garden for her vegetable she wants the frame to have dimension X feet by X +3 feet if she wants the garden to have a maximum area of 50 ft.² what are the possible values of X

**Answer: **0ft < X ≤ 5.73ft

**Step-by-step explanation:**

In this case, we have a rectangle.

For a rectangle of length L and width W, the area is:

A = L*W.

And we have:

L = X

W = X + 3ft.

Then the area will be:

A = X*(X + 3ft) = X^2 + 3ft*X.

And we want to have a maximum area of 50ft^2.

Then we can write:

A = X^2 + 3ft*X ≤ 50ft^2

Now let's solve this for X.

Now, the first thing we can see is that both coefficients in our quadratic equation are positive, so as the absolute value of X increases, also does the whole equation.

Then makes sense start for the upper limit of X, this is when:

X^2 + 3ft*X = 50ft^2.

Now we can solve the quadratic equation:

X^2 + 3ft*X - 50ft^2 = 0

Applying the Bhaskara formula, the solutions are:

[tex]X = \frac{-3ft +- \sqrt{(3ft)^2 - 4*1*(-50ft^2)} }{2} = \frac{-3ft +-14.46ft }{2}[/tex]

Then we have two solutions:

X = (-3ft - 14.46ft)/2 = -8.73 ft.

X = (-3ft + 14.46ft)/2 = 5.73 ft

Because X represents a distance, it can only be positive, then we must select the option X = 5.73ft.

This is the maximum value of X, and we will have:

0ft < X ≤ 5.73ft

Where the lower limit is there because we can not have X = 0ft, as this does not have physical meaning.

Find the value of a and b when x =10

**Answer:**

A=250

B=10

**Step-by-step explanation:**

You plug in 10 for x and solve

Let’s do a first.

So to start, we need to substitute 10 into the equation, so:

a = 5 x (10 squared) / 2

Which can be simplified to

a = 5 x 100 / 2

a = 500 / 2

a = 250

Now onto b. Again, we need to substitute 10 into the equation, so:

b = (2 x (10 squared))(10 - 5) / 10 x 10

Which can be simplified to

b = (2 x 100)(10 - 5) / 10 x 10

b = 200(10 - 5) / 10 x 10

b = 200(5) / 10 x 10

b = 1000 / 10 x 10

b = 1000 / 100

b = 10

So to start, we need to substitute 10 into the equation, so:

a = 5 x (10 squared) / 2

Which can be simplified to

a = 5 x 100 / 2

a = 500 / 2

a = 250

Now onto b. Again, we need to substitute 10 into the equation, so:

b = (2 x (10 squared))(10 - 5) / 10 x 10

Which can be simplified to

b = (2 x 100)(10 - 5) / 10 x 10

b = 200(10 - 5) / 10 x 10

b = 200(5) / 10 x 10

b = 1000 / 10 x 10

b = 1000 / 100

b = 10

Kevin and monica lead visitor tours at a museum. Last month, both kevin and monica led the same number of vistors. Kevin lead 150 adults, plus 6 student groups. Monica led 134 adults, plus 8 student groups. If each student group had the same number of students, which equation could be used to determine the number of students in each group?

Answer:

Number of students in each group = 8

Step-by-step explanation:

kevin and monica led the same number of vistors.

Let x = number of students in each group

Kevin lead 150 adults, plus 6 student groups.

150 + 6x

Monica led 134 adults, plus 8 student groups.

134 + 8x

Equate both equations

150 + 6x = 134 + 8x

Collect like terms

150 - 134 = 8x - 6x

16 = 2x

Divide both sides by 2

x = 16 / 2

= 8

x = 8

Number of students in each group = 8
