Your internet provider offers two different plans. One plan costs $.02 per email
plus a $9 monthly service charge. The other plan costs $.05 per email with no
service charge.
a. Write a system of equations to model the cost of the two internet plans.
b. For how many email messages will both plans cost the same?
c. If you send and receive about 500 email messages per month, which plan
should you use?
Answers
a.) y= 0.2x + 9 and y= 0.5x
b.) 30 emails
c.) the first plan
Step-by-step explanation:
a.) cost per email is a variable
b.) graph and find intersection of the lines
c.) plug in 500 for x in both equations
The number of email messages where both plans will cost the same will be 300 messages.
The system of equations to model the cost of the two internet plans based on the information given will be:
Internet provider 1 = 9 + 0.02m
Internet provider 2 = 0.05m
where m = number of mails
The number of email messages where both plans will cost the same will be:
9 + 0.02m = 0.05m
Collect like terms
0.05m - 0.02m = 9
0.03m = 9
m = 9/0.03
m = 300
When there's 500 messages for the month, the cost for each plan will be:
Internet provider 1 = 9 + 0.02m
= 9 + 0.02(500)
= 9 + 10
= 19
Internet provider 2 = 0.05m
= 0.05(500)
= 25
Therefore, based on the calculation, the first plan is cheaper.

2x=0-20
2x=-20
x=-20/2
x= -10
Answer:
x = -10
Step-by-step explanation:

Step-by-step explanation:
physics convention 11 companies set up equal sized square booths in a row along one wall of a convention center.The booths are adjacent to each other and a 2-ft wide walkway surrounds the block of booths on three sides. The total area of the booths and walkway is 1200 ft^2. What is the side length of each booth?
Answers
Answer:
Side length of each booth is 8.35 ft approximately.
Step-by-step explanation:
There are 11 companies set up equal sized square booths in a row along one wall of a convention center.
Now, refer the diagram to answer the problem.
It is given area is 1200.
So, length x width =1200
(11x+24)(x+2)=1200
Multiply using FOIL method.
[tex]11x^{2}[/tex]+22x+24x+48=1200
[tex]11x^{2}[/tex]+46x+48-1200=0
[tex]11x^{2}[/tex]+46x-1152=0
Solve using quadratic formula
x=[tex]\frac{-46+/- \sqrt{46^{2}-4(11)(-1152 } }{2(11)}[/tex]
x=[tex]\frac{-46+/-\sqrt{2116+50688} }{22}[/tex]
x=[tex]\frac{-46+/-\sqrt{52804} }{22}[/tex]
Simplify it
[tex]x=\frac{-49+/- 229.79}{22}[/tex]
Simplify to get two values for x.
x=8.35; x=-12.67
Here negative does not work.
Side length of each booth is 8.35 ft.

Step-by-step explanation:
G)
all angles of a triangle add up to 180.
the square in the bottom right of the triangle is 90 btw
2x + x + 90 = 180
3x + 90 = 180
3x + 90 - 90 = 180 - 90
3x = 180 - 90
3x = 90
3x/3 = 90/3
x = 30
H)
this is an Isosceles triangle.
that means the bottom two angles are equal.
75 + 75 + x = 180
x + 150 = 180
x + 150 - 150 = 180 - 150
x = 180 - 150
x = 30
I)
2m is supplementary to the bottom right angle of the triangle.
that means they add together to make 180.
80 + 30 + (180 - 2m) = 180
110 - 2m = 180 - 180
110 - 2m = 0
110 = 2m
110/2 = m
55 = m
J)
to save time I'm not going to write out the steps, its the same as the i.
2x + 3x + (180 - 120 ) = 180
5x + 60 = 180
5x = 180 - 60
5x = 120
x = 120/5
x = 24
K)
imagine this as a triangle and a square.
sorry I'm not sure how to explain this -.-
but the equation would be

2k = 90
k = 45

Solve 6kx = 4kx + 8 for x.
Start by collecting the variable terms on the same side of the equation.
What is the first step?
Answers
Answer:
x = 4k
Step-by-step explanation:
6kx = 4kx + 8
The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.
2kx = 8
Next, move the 2k to the right side of the = by dividing both sides by 2k
x = 8/2k
The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.
x = 4k

How do you solve a perpendicular equation?
Answers
Step-by-step explanation:
First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

The slope of the line is [tex]\frac{-5}{3}[/tex] ⇒ D.
Step-by-step explanation:
The rule of the slope of a line is
m = [tex]\frac{y2-y1}{x2-x1}[/tex] (x1, y1) and (x2, y2) are two points lie on the lineUse the given figure to find two points on the line
→ From the given figure
∵ The line passes through points (0, 2) and (3, -3)
∴ x1 = 0 and y1 = 2
∴ x2 = 3 and y2 = -3
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-3-2}{3-0}=\frac{-5}{3}[/tex]
∴ m = [tex]\frac{-5}{3}[/tex]
∴ The slope of the line is [tex]\frac{-5}{3}[/tex]
