Step-by-step explanation:

There is no change in x-coordinate. The line is parallel to y-axis.

Equation of line : x = 5

Answer:

The coordinates of the point are (-4.5,-1).

Step-by-step explanation:

We want to find point T(x,y).

I am going to say that out points are A(-8,-2) and B(6,2)

Since it partitions the segment in a 1:3 ratio, we have that:.

[tex]T - A = \frac{1}{1+3}(B-A)[/tex]

[tex]T - A = \frac{1}{4}(B-A)[/tex]

We apply this to both the x-coordinate and y-coordinate of T.

x-coordinate:

x-coordinate of A: -8

x-coordinate of B: 6

x-coordinate of T: x.

So

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]x - (-8) = \frac{1}{4}(6-(-8))[/tex]

[tex]x + 8 = \frac{14}{4}[/tex]

[tex]x = \frac{14}{4} - 8[/tex]

[tex]x = \frac{14}{4} - \frac{32}{4}[/tex]

[tex]x = -\frac{18}{4}[/tex]

[tex]x = -4.5[/tex]

y-coordinate:

y-coordinate of A: -2

y-coordinate of B: 2

y-coordinate of T: y.

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]y - (-2) = \frac{1}{4}(2-(-2))[/tex]

[tex]y + 2 = 1[/tex]

[tex]y = -1[/tex]

The coordinates of the point are (-4.5,-1).

Step-by-step explanation:

The first price reduction reduced the price to (1 -20%) = 0.80 times the original. The second price reduction reduced the price to ...

  0.80(1 -25%) = 0.80×0.75 = 0.60

times the original.

The final price was ...

  1800 × 0.60 = 1080

Answer:

2h-2=92 and h-2=92-h.

Step-by-step explanation:

Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.

The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.

Combining like terms we would have the first correct choice, 2h-2=92.

Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.

The equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the age of Hannah be x. and Since the age of Hannah and Anthony are two consecutive odd integers, therefore, the age of Anthony will be (x+2).

As it is given that the sum of the ages of the two other person is 92, therefore, the equation that will represent the sum of the age of the two persons can be written as,

[tex]x+(x+2)=92\\\\x+x+2=92\\\\2x+2=92[/tex]

Thus, the equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.

Answer:

-8/15 is less than 10/18 so <

Step-by-step explanation:

Problem 7

Consider the general template

g(x) = a*sqrt(x-h) + k

and compare it to the general parent function

f(x) = sqrt(x)

We have the following variables: a, h and k

They are defined as such:

For this problem, we have

Since g(x) = sqrt(x+4)+3 is the same as g(x) = 1*sqrt(x - (-4)) + 3

With a = 1, we know that the curve moves upward. Compared to the parent graph y = sqrt(x), which also goes upward, no reflection has been done over the x axis.

The h = -4 means we shift 4 units to the left

The k = 3 means we shift 3 units up

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

Problem 8

We'll use the ideas mentioned in problem 7. They'll also be used for problems 9 and 10 as well.

For problem 8, we have

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

Problem 9

This time we have

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

Problem 10

So far, all of the 'a' values have been positive 1. This means that there hasn't been any reflection or vertical stretching going on.

This time we have a = -1 instead of a = 1.

So we will reflect over the x axis along with the shiftings similar to the ones that occurred with the previous problems.

Answer:

  17

Step-by-step explanation:

The number of handshakes among n people is n(n -1)/2. Then ...

  n(n -1)/2 = 136

  n(n -1) = 272 = 17×16*

  n = 17

There were 17 people at the party.

_____

* This factoring can be facilitated by recognition that √272 ≈ 16.5, the number midway between the consecutive factors.

Answer:

The midpoint is (3, 3).

Step-by-step explanation:

We are given the two points A(9, 11) and B(-3, -5).

The midpoint is given by:

[tex]\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)[/tex]

So:

[tex]\displaystyle M = \Big( \frac{9+(-3) }{2}, \frac{ 11+(-5) }{2} \Big) = (3,3)[/tex]

The midpoint is (3, 3).

We want to show that AM = MB.

We can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

The distance between A(9, 11) and M(3, 3) will then be:

[tex]AM=\sqrt{(9-3)^2+(11-3)^2}=\sqrt{6^2+8^2}=\sqrt{100}=10[/tex]

And the distance between B(-3, -5) and M(3, 3) will be:

[tex]MB = \sqrt{ (3-(-3))^2 + (3-(-5))^2 } = \sqrt{(6)^2+(8)^2} = \sqrt{ 100 } = 10[/tex]

So, AM = MB = 10.

Since AM = MB = 10, AM + MB = 10 + 10 = 20.

So, we want to prove that AB = 20.

By the distance formula:

[tex]AB=\sqrt{(9-(-3))^2+(11-(-5))^2}=\sqrt{12^2+16^2}}=\sqrt{400}=20\stackrel{\checkmark}{=}20[/tex]
