Solve for x. -4(-2x - 2) + x - 2 = -48
Answer:
x = -5.7778
Step-by-step explanation:
1) 8x + 8 + x -2 = 48 (You multiply the -4 into both -2x and -2, thus getting rid of the brackets)
2) 9x + 6 = -48 (Add the two values of x (8x + x) and then subtract the 2 from 8 = 6)
3) 9x =-46 - 6 (Move the 6 mover, which will change its sign from a (+) to a (-6))
4) 9x = -52 (Do the expression, and you get -52)
5) x = -52 / 9 (Isolate the x, by dividing both sides by it)
6) x = -5.7778 (Round the answer)

Multiple Choice The perimeter of a square
is 68 m. If one side is represented by 3x + 2,
what is the value of x?
A 3
B 5
C 4
D 6
E 10
Answer:
The answer is B, 5.
Step-by-step explanation:
3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).
12x+8 = 68
12x = 60
divide both sides by 12...
60/12 = 5.
Therefore x =5

Your family spends $30 for tickets to an aquarium and $3 per hour for parking. Write an equation that gives the total cost of your family's visit to the aquarium as a function of the number of hours that you are there. Find the total cost of 4 hours at the aquarium
Answer:
Equation: y=$3(x)+$30
Total cost $42
Step-by-step explanation:
Calculation to Find the total cost of 4 hours at the aquarium using this formula
y=mx+b
Where,
y intercept=Total cost
m=$3 per hour
b=$30 Tickets
x=4 hours
Let plug in the formula
First step is to form the equation
y=$3(x)+$30
Second step is to substitute 4 hours for m and b
y=$3(4)+$30
Hence:
y=$12+$30
y=$42
Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42
Write the number
five million four thousand three hundred

Which equation is a linear function?
y=2^x -1
y=x/2-5
y=2/x +3
y=x^2 +7
Answer:
Second Choice.
Step-by-step explanation:
[tex]y = mx + b[/tex]
That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.
So we can cut out the first and last choice.
Then we have only two choices which are
[tex]y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3[/tex]
The second equation is called Rational Function where a variable is a denominator.
Therefore, the correct answer is second choice.

The formula for finding out the quartiles didn’t work when I tried it.
I just figured it out so I’ll answer it on this account lol.
Q1 = 32, Q2 = 45, Q3 = 52
Interquartile range = 52 - 32 = 20
Range = 68 - 21 = 47

Determine the 16th term in the sequence defined by: A_n = 5–2(n-1)
Answer: 45
Step-by-step explanation:
[tex]a_{n} = 5 - 2(n - 1)\\a_{16} = 5-2 (16-1)\\a_{16} = 5-2 (15)\\a_{16} = 3 (15)\\a_{16} =45[/tex]
Answer:
-25Step-by-step explanation:
aₙ = 5–2(n-1) = 5 - 2n + 2 = 7 - 2nSubstitute n with 16 for the 16th term
a₁₆ = 7 - 2(16) = 7 - 32 = -25Lupe's car averages 27 miles per gallon of gas. At that rate, how far would it go on 27 gallons?
