Urgent help on math plz

Answers

Answer:

x = 14

Step-by-step explanation:

First, organize your work by showing that lines are similar

Line KV is similar to line RV

Line UV is similar to line LV

etc, etc.

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

Now notice that line KV and line RV have the numbers 9 and 18 accordingly

and notice that it's an x2 difference.

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

Now apply the same thing to line UV and LV and divide 26 by 2

That gets us 13

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

Now plug 13 into the equation (2x - 15)

2x - 15 = 13

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

Now solve for X

2x - 15 = 13

Add 15 to each side

2x − 15 + 15 =13 + 15

2x = 28

Divide both sides by 2

2x / 2 = 28 / 2

x = 14

Answers

Answer:

AB = 51

BC = 50

AC = 42

PQ = 42

QR = 42

PR = 59

Step-by-step explanation:

Perimeter of ∆ ABC = Perimeter of ∆ PQR

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3

9x + 17 = 10x + 3

17 - 3 = 10x - 9x

14 = x

.: x = 14

AB = 3x +9 = 3×14+9 = 42+9 = 51

BC = 3x +8 = 3×14+8 = 42+8 = 50

AC = 3x = 3×14 = 42

PQ = 3x = 3×14 = 42

QR = 3x = 3×14 = 42

PR = 4x +3 = 4×14+3 = 56+3 = 59

Answers

Answer: (x,y) -> (x,-y)

Step-by-step explanation:

If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.

Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?​

Answers

Answer:

slope =[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]

Thus, the slope is [tex]-\frac{2}{3}[/tex].

Answer:

Greatest common factor of 17

So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!

Add and subtract the second term to the expression and factor by grouping.
