Step-by-step explanation:

Answer: Choice D) As the side length increases by 1, the area increases and then decreases by an equal factor

=============================================================

Explanation:

Choice A is ruled out because the area does change. As x changes, y changes as well. This rules out choice B as well.

Choice C is somewhat close. However, it's not entirely true since the area doesn't increase by the same amount. For instance, the jump from points (2,18) to (3,24) indicate that the jump in y value is +6. But going from (3,24) to (4,28) shows a jump of +4 in the y value. So we can rule out choice C.

This means that choice D is the final answer.

Answer:

  z = 9/2

Step-by-step explanation:

The triangles in the figure are all similar, so the side lengths are proportional.

  long side/hypotenuse = z/6 = 6/8

  z = 36/8 = 9/2 . . . . multiply by 6

Answer:

(4, -11)

Step-by-step explanation:

We are given the system of equations:

[tex]\displaystyle \begin{cases} 3x+2y=-10\\ y=-5x+9\end{cases}[/tex]

And we want to solve by substitution.

Notice that y is isolated in the second equation.

Therefore, we can substitute the second equation into the first. This gives us:

[tex]3x+2(-5x+9)=-10[/tex]

Now, we can solve for x.

First, distribute:

[tex]\displaystyle 3x-10x+18=-10[/tex]

Next, we can combine like terms:

[tex]-7x+18=-10[/tex]

Subtract 18 from both sides:

[tex]-7x=-28[/tex]

And divide both sides by -7:

[tex]x=4[/tex]

So, the value of x is 4.

Using the second equation then, we can solve for y:

[tex]y=-5x+9[/tex]

Since we know that x = 4:

[tex]\displaystyle y = - 5(4) + 9 = -20 + 9 = -11[/tex]

So, our solution is (4, -11).

To check, we can simply substitute the x and y values and see if the two equations are true.

For the first equation:

[tex]3(4)+2(-11)=12-22=-10\stackrel{\checkmark}{=}-10[/tex]

And for the second equation:

[tex]-5(4)+9=-20+9=-11\stackrel{\checkmark}{=}-11[/tex]

Since both statements are true, (4, -11) is indeed correct!

Answer:The difference between the number of children and adults=153

Step-by-step explanation:

ratio of men to women to children is 1:3:20

Total RATIO = 1+ 3+ 20= 24

Number of men = ratio of men / Total ratio x  Total Number of people on the trip =

= 1/24 x 216= 9 men

Number of women=ratio of women / Total ratio x  Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women

Number of children=ratio of Children/ Total ratio x  Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children

The difference between the number of children and adults will be 180 -27 = 153

Answer: 198 miles

Step-by-step explanation:

Here's the complete question:

The Nile river is 4160 miles long, you want to spend three weeks traveling the entire length of the river. Estimate the number of miles you should travel each day.

We should note that 7days = 1 week

3 weeks = 3 × 7 = 21 days.

The number of miles that should be travelled each day will be:

= 4160 / 21

= 198 miles

Answer:

C =-x + 550

Step-by-step explanation:

Complete question

At $350 per person, an airline anticipates selling 200 tickets for a particular flight. At $450 per person the airline anticipates selling 100 tickets for the same flight .Find the linear equation between the cost per ticket and the number of tickets.

Find the complete question attached

Let x be the total number of tickets sold

C be the cost per ticket

If C = $350, x = 200

when C = $450, x = 100

Get the slope

m = C2-C1/x2-x1

m = 450-350/100-200

m = 100/-100

m = -1

Substituting into the point slope form of the equation;

C - C1 = m(x-x1)

Substituting m = -1, C1 = 350 and x1 = 200

C - 350 = -1(x-200)

C - 350 = -x + 200

C = -x + 200 + 350

C = -x + 550

Hence the required linear equation is C =-x + 550

The linear equation should be C =-x + 550

Here we assume x be the total number of tickets sold

And,

C be the cost per ticket

Since C = $350, x = 200 and C = $450, x = 100

So, here the slope should be

[tex]m = C2-C1\div x2-x1\\\\m = 450-350\div 100-200\\\\m = 100\div -100[/tex]

m = -1

Now here we Substituting into the point slope form

So,

C - C1 = m(x-x1)

Here m = -1, C1 = 350 and x1 = 200

Now

C - 350 = -1(x-200)

C - 350 = -x + 200

C = -x + 200 + 350

C = -x + 550
