The answer is 26. I got this answer by plotting out the points on a coordinate plane and counting the perimeter around the shape to get 26. Hope this helps! :)

Answer:

Step-by-step explanation:

Firstly, plot the points on graph paper which you can find on the internet. The first number in the ordered pair, (the ones in parenthesis), is the x coordinate. The other number is the y coordinate. Put these onto a graph which is attached. The perimeter is 26.

-15 + 12x = 5x + 7 -3x SOLVE FOR X

Natali [406]

Answer: $x=\frac{11}{5}$

Simplify both sides of the equation

$-15+12x=5x+7+-3x$

$12x-15=(5x+-3x)+(7)$ (Combine Like Terms)

$12x-15=2x+7$

Subtract 2x from both sides

$12x-15-2x=2x+7-2x\\10x-15=7$

Divide both sides by 10

$\frac{10x}{10} =\frac{22}{10}$

$x=\frac{11}{5}$

What is the slope of the line that passes through the points (3, 4) and (5, –4)?

balandron [24]

M = -4 -4 / 5- 3 = -8/2 = -4

y = -4x + b

4 = -12 + b

b = 16

y = -4x + 16

I don’t really understand how you figure out the points of a figure on rotation, please explain!

Basile [38]

To rotate a figure
90 degrees(-y,x)
180 degrees(-x,-y)
270 degrees(y,-x)
If your original point is (1,2) or example and you want to rotate it say 270 degrees the final point would be (2,-1)
Hope this helped!!!!!

Please help me solve the expression for “n”

Bingel [31]

Answer:

n = 2

Step-by-step explanation:

In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:

n + 7 = 9

n = 9 -7 . . . . . . subtract 7 from both sides of the equation

n = 2

___

Alternatively, you can simplify the given expression:

$\dfrac{9^n(9^7)}{9^9}=1=\dfrac{9^n}{9^2}$

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
