Answer:
[tex] 2 + \sqrt{3} [/tex]
Step-by-step explanation:
[tex] \dfrac{1}{\sqrt{4} - \sqrt{3}} = [/tex]
[tex] = \dfrac{1}{2 - \sqrt{3}} [/tex]
[tex] = \dfrac{1}{2 - \sqrt{3}} \times \dfrac{2 + \sqrt{3}}{2 + \sqrt{3}} [/tex]
[tex] = \dfrac{2 + \sqrt{3}}{(2 - \sqrt{3})(2 + \sqrt{3})} [/tex]
[tex] = \dfrac{2 + \sqrt{3}}{4 - 3} [/tex]
[tex] = \dfrac{2 + \sqrt{3}}{1} [/tex]
[tex] = 2 + \sqrt{3} [/tex]

Principal Simons purchases boxes of pens for her school at an online store. The store charges her the same amount for each box of pens plus a flat shipping fee for any number of boxes she purchases. Selected numbers of boxes and the corresponding total cost including the shipping fee for that number of boxes are shown in the table. Let t be a function that models the total cost including the shipping fee, in dollars, to purchase p boxes of pens. Based on the values in the table, which of the following best defines the function t ?

What is the exact length of AB?
Answer:
AB = 5[tex]\sqrt{6}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
AB² + BC² = AC²
AB² + (2[tex]\sqrt{3}[/tex] )² = (9[tex]\sqrt{2}[/tex] )²
AB² + 12 = 162 ( subtract 12 from both sides )
AB² = 150 ( take square root of both sides )
AB = [tex]\sqrt{150}[/tex] = [tex]\sqrt{25(6)}[/tex] = [tex]\sqrt{25}[/tex] × [tex]\sqrt{6}[/tex] = 5[tex]\sqrt{6}[/tex]
Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
y=-3x-5.
Step-by-step explanation:
1) the slope-intercetion form is: y=s*x+i, where 's' and 'i' are slope and interception - unknown numbers;
2) if A(-2;1) and B(2;-11), then the slope can be calculated:
[tex]s=\frac{Y_B-Y_A}{X_B-X_A}=\frac{-11-1}{2+2}=-3;[/tex]
3) midpoint of AB has coordinates (0;'i') - interception point , where i - needed number. Then i=1/2*(-11+1)=-5;
4) If s=-3 and i=-5, then the required equation is:
y=-3x-5.

Find the perimeter of ABCD and please explain how you found it.
Answer:
157
Step-by-step explanation:
We can already tell that these two figures are congruent due to the angles (if you remember, the "top" and "bottom" angles of trapezoids form 180 degrees). Since we know that these are congruent, we know that GH = BC, and so on. We can then plug in the missing sides by looking at the figure that has the sides. Thus, giving us 157. Hope this wasn't too complicated!

3x+3y= 27
x-3y= -11
what is x and y???
Answer:
x=4,y=5
Step-by-step explanation:
3x+3y=27
x-3y=-11 (3y and -3y cancel each other out)
4x=16
x=4
4-3y=-11 (plug 4 into the x-value of an priginal equation)
-3y=-15

11. Pristine House Cleaners charges $40 plus $18 per room. Sparkle House Cleaners charges $64
plus $14 room. Write and solve an equation to find the number of rooms for which the total cost of
both house cleaners is the same.
Answer:
6 rooms
Step-by-step explanation:
Let x = price per room
y = total cost
Pristine charges $18 per room, so multiply x by 18 like this: 18x
They also add $40 on top of that to make up the total cost
y = 18x + 40
Sparkle charges $14 per room, so multiply x by 14 and add 64 for total cost
y = 14x + 64
To find out how many rooms they would need to clean for the same price, make them equal to each other
18x + 40 = 14x + 64
Move like terms together by subtracting 14x from both sides
18x + 40 = 14x + 64
- 14x - 14x
4x + 40 = 64
Subtract 40 from both sides
4x + 40 = 64
- 40 - 40
4x = 24
Then divide both sides by
4x/4 = 24/4
x = 6

3.
Write an equation for the line that is parallel to the given line and that passes through the given point.
y = –5x + 3; (–6, 3)
A. y = –5x – 27
B. y = 5x – 9
C. y = –5x + 9
D. y = –5x + 27
Answer:
A. y = –5x – 27
Step-by-step explanation:
You would need a new y-intercept in order for this to be parallel. So you use the points given and the slope and fill it in. 3=-5(-6)+b. 3=30+b. Then subtract 30 from both sides. -27=b. Then just put it all back into slope intercept form. y=-5x-27.
y = –5x + 3
slope of the given line by comparing with y=mx+b is
m= - 5
Concept is that the slope of parallel lines are equal so we need a line with slope same as m=-5
and passes through point (-6,3)
Equation using the point slope equation
y-3 = -5 (x-(-6))
y-3=-5(x+6)
y-3= -5x-30
y= -5x -27

Answer:
1 1/3
Step-by-step explanation:
2/5 x 10/3
Multiply across -
10 x 2 = 20
5 x 3 = 15
20/15
Simplify -
20/15 to 4/3
Divide 4 by 3
You get 1 1/3
Answer:
4/3
Step-by-step explanation:
multiply (top) numerator x numerator and (bottom) denominator x denominator2 x 10 = 20 and 5 x 3 = 15 or 20/15 So, 2/5 x 10/3 = 20/15reduce 20/15 to simplest terms, both are divisible by 5divide both numerator and denominator by 5 and get:20/15 = 4/3So, 2/5 x 10/3 = 4/3
