Cruise ships in the Jolly Cruise Line charge $14.45 per day for access to their premium WI- Fi. Each minute you use the internet you are charged $0.75. Which equation below represents this situation, if y represents the total amount you are charged for the day and a represents the number of minutes you use the Wi-Fi
y= 14.45x + 0.75
y= 14.45x - 0.75
y= 14.45 - 0.75x
y= 14.44 + 0.75x
Answer:
The equation y = 14.45 + 0.75x represent the situation.
Step-by-step explanation:
Given that:
Cost charged to access the premium wifi = $14.45
Cost charged each minute = $0.75
Let,
x represent the number of minutes
y represent the total amount charged
y = 14.45 + 0.75x
Hence,
The equation y = 14.45 + 0.75x represent the situation.

Which of the following functions represents f(n), the number of small squares in figure n?
a.f(n)=4n^2+2
b.f(n)=n^2+5
c.f(n)=(n+1)^2+2
d.f(n)=(n+1) (n+2)
Answer:
c. f(n) = (n+1)^2 + 2
Step-by-step explanation:
It is c. because...
f(n) = (1+1)^2 + 2
2^2 + 2
4 + 2 = 6 (first term)
f(n) = (2+1)^2 + 2
3^2 + 2
9 + 2 = 11 (second term)
f(n) = (3+1)^2 + 2
4^2 + 2
16 + 2 = 18 (third term)
(help pls) Determine the domain of the function, and choose the correct interval and inequality notations. f(x) = 1/2x + 8
Answer:
INTERVAL NOTATION: (-4) (-4) -- (BOTH ARE -4)
INEQUALITY: >-4 OR X<-4

A small box holds 40 stuffed toys. A large box holds 150% as many stuffed toys as than a small box how many stuffed toy does the large box hold.
Answer: 60
Step-by-step explanation:
From the question, we are informed that a small box holds 40 stuffed toys and that a large box holds 150% as many stuffed toys as that of a small box.
The number of stuffed toy that the large box hold would be calculated as:
= 150% × 40
= 150/100 × 40
= 1.5 × 40
= 60
8x - 16 = -4x - 4(1-6x)
please show work
Answer:
x= -1
Step-by-step explanation:
8x - 16 = -4x - 4(1-6x)
8x - 16 = -4x - 4+24x
8x - 16 = 20x-4
8x - 16+16 = 20x-4+16
8x = 20x+12
8x-20x = 20x-20x+12
-12x=12
Divide both by -12, and you get -1.
[tex]8x - 16 = - 4x -4 + 24x[/tex]
Solve the equation for x-term by making x as the subject.[tex]8x + 4x - 24x = 16 - 4 \\ 12x - 24x = 12 \\ - 12x = 12 \\ x = \frac{12}{ - 12} \Longrightarrow \frac{1}{ - 1} \Longrightarrow - 1 \\ x = - 1[/tex]
Answer Check by substituting x = -1 in the equation.[tex]8( - 1) - 16 = - 4( - 1) - 4 + 24( - 1) \\ - 8 - 16 = 4 - 4 - 24 \\ - 24 = 0 - 24 \\ - 24 = - 24[/tex]
The equation is true for x = -1.

Simplify 9xºy-3 Write your answer using only positive exponents.
Answer:
we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]
Step-by-step explanation:
Given the expression
[tex]9x^0y^{-3}[/tex]
Apply exponent rule: [tex]a^{-b}=\frac{1}{a^b}[/tex]
[tex]\:9x^0y^{-3}=9\cdot \:\frac{1}{y^3}x^0[/tex]
Apply rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]=9\cdot \:1\cdot \frac{1}{y^3}[/tex]
Multiply fractions: [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]
[tex]=1\cdot \frac{1\cdot \:9}{y^3}[/tex]
Refine
[tex]=\frac{9}{y^3}[/tex]
Thus, we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]

Answer:
x=65
Step-by-step explanation:
Step 1: Add -3 to both sides.
√x−1+3+−3=11+−3
√x−1=8
Step 2: Solve Square Root.
√x−1=8
x−1=82(Square both sides)
x−1=64
x−1+1=64+1(Add 1 to both sides)
x=65
Check answers. (Plug them in to make sure they work.)
x=65(Works in original equation)

Answer:
C. 60%
Step-by-step explanation:
Consider 1st row of table
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
Consider 2nd row of table
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%

5. Mississippi and Georgia have a total of 21 electoral votes. Mississippi has 6 electoral votes. Use mental math or the guess, check, and revise strategy to solve the equation 6 + g = 21 to find g, the number of electoral votes Georgia has.
Answer: g = 15 . Georgia has 15 electoral votes.
Step-by-step explanation:
Mental math: How many do I need to make up the difference?
counting by 5s: 5, 10 15, 20.
6 is one more than 5.
From 5, three more 5's gets us close to 20. It works.
6 + 15 = 21
I'm not smart and I stink at math so can someone plz help me 12/x = 8
1. We need to get rid of all the denominator in this equation.
This can be done by multiplying left and right sides by the LCD.In the problem: 12/x = 8, the LCD is X.12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
