19) 20)
The expression would be: 
3x+4x+5x
If x=8, the perimeter would be:
3(8)+4(8)+5(8)
24+32+40
=96 feet

21) 22)
The expression would be:
x+14+5+7+5.5+2x
If x=10.5, the perimeter would be:
10.5+14+5+7+5.5+2(10.5)
10.5+14+5+7+5.5+21
=63 feet 

Hope this helps.

castortr0y [4]
If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:

15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58

$43.89 - $6.58 = $37.31

5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87

$37.31 - $1.87 = $35.44

The correct result would be <span>$35.44.</span>

Identify an equation in point-slope form for the line perpendicular to
Alchen [17]

Answer:

y - 9 = \frac{1}{2}(x +3)

Step-by-step explanation:

Given

Function; y = -2x + 8

Required

Find an equation perpendicular to the given function if it passes through (-3,9)

First, we need to determine the slope of:  y = -2x + 8

The slope intercept of an equation is in form;

y = mx + b

<em>Where m represent the slope</em>

Comparing  y = m_1x + b to y = -2x + 8;

We'll have that

m_1 = -2

Going from there; we need to calculate the slope of the parallel line

The condition for parallel line is;

m_1 * m_2 = -1

Substitute m_1 = -2

(-2) * m_2 = -1

Divide both sides by -2

m_2 =\frac{ -1}{-2}

m_2 =\frac{1}{2}

The point slope form of a line is;

y - y_1 = m_2(x - x_1)

Where (x_1,y_1) = (-3,9) and m_2 =\frac{1}{2}

y - y_1 = m_2(x - x_1)becomes

y - 9 = \frac{1}{2}(x - (-3))

Open the inner bracket

y - 9 = \frac{1}{2}(x +3)

<em>Hence, the point slope form of the perpendicular line is: </em>

<em />y - 9 = \frac{1}{2}(x +3)<em />

Maria figure that the bowling balls on a rack weighed a total of 240 lb how many 16 pound bowling balls weigh a total of 240 lbs
Naddik [55]

240 = 16x is about an equation but you can make it more complicated by adding unneeded parts for example 240 = 16x - 81 + ((15x) + 15) - (x^2 / 2) - 45 - 1.5.

Which graph shows the points (–3, 5) and (4, –3) plotted correctly?
Nana76 [90]

Answer:

Step-by-step explanation:

This is clearly a linear relationship.  If Alex rented the movie for 0 days, he'd owe nothing.  If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.

Using this formula, we find three particular points on the graph:

(1, $2), (2, $4), (3, ($6)
