Use the rules of equations and inverse operations to solve the equation. In your final answer, include all of your work.
x^3 + 3 = 57
Answer:
x=3*2 1/3
Step-by-step explanation:
In order to solve this non-linear equation, we need to move all the terms to the left side.
In our example,
- term 3, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
(x^3 + 3) + (-3) = 57 + (-3)
We need to get rid of expression parentheses.
If there is a negative sign in front of it, each term within the expression changes sign.
Otherwise, the expression remains unchanged.
In our example, there are no negative expressions.
x^3 + 3 - 3 = 57 - 3
Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. These are the tiles she has drawn so far: red, red, blue, yellow, blue, red, green, red, blue, green Based on this data, a. What is the probability that her next draw will be red? 40 b. What is the probability that her next draw will NOT be blue? c. If she draws 70 more times, how many times would you expect a green?
Answer:
A) 0.7
B) 0.2
C) 14 times
Step-by-step explanation:
We are told that the tiles she has drawn so far are;
red, red, blue, yellow, blue, red, green, red, blue, green.
In this, we have 10 number.
So for the first 10 number of tiles, she had:
4 red tiles
3 blue tiles
1 yellow tile
2 green tiles
A) probability that her next draw will be red = number of red tiles/total number of initial tiles drawn = 4/10 = 0.4
B) probability that her next draw will NOT be blue = number of tiles that are not blue/total number of initial tiles drawn = 7/10 = 0.7
C) Probability that the next draw will be green = number of tiles that are green/total number of initial tiles drawn = 2/10 = 0.2
Now, if she draws 70 more times, number of times she will expect a gree tile = 0.2 × 70 = 14 times

Find the slope of the line with the following points:
(9,3) & (-2,6)
Answer:
m=-0.2727272727
Step-by-step explanation:
Use the formula m=(y *2 - y *1) / (x *2 - x *1)
So it will be (6-3) / ((-2)-9)
Which results in 3/-11 = -0.272727272727272

Write an equation of the line passing through the point (4,3) that is perpendicular to the line 4x-7x=9
Answer:
The equation 4x-7x=9 simplifies into x=-3, which is a horizontal line. A perpendicular line would be vertical, and the equation for vertical lines is y=b, b being a constant. In this case on the point (4,3), y is 3, so the equation of the line is y=3.

The function y = 3.75 +1.5(x - 1) can be used to determine the cost in dollars for a taxi ride
of x miles. What is the rate of change of the cost in dollars with respect to the number of
miles?
Answer:
$1.50 per mile
Step-by-step explanation:
y = 3.75 + 1.5(x - 1)
~Simplify left side
y = 3.75 + 1.5x - 1.5
~Combine like terms
y = 2.25 + 1.5x
As we can see, this question is written in slope-intercept form [ y = mx + b ] where m = slope and b = y-intercept.
1.5x resembles the slope (cost of how many miles you ride in the taxi)
2.25 resembles the y-intercept. We can just assume this is the "fee or tip" amount since the question doesn't state what this actually is.
Since 1.5 is the slope, this is the rate of change.
Best of Luck!
The rate of change of cost with respect to the number of miles is 1.5 dollars per mile.
Given information:
The function [tex]y = 3.75 +1.5(x - 1)[/tex] can be used to determine the cost in dollars for a taxi ride of x miles.
It is required to calculate the rate of change of cost with respect to the distance traveled.
The rate of change of cost can be measured as,
[tex]y = 3.75 +1.5(x - 1)\\y = 3.75 +1.5x - 1.5\\\dfrac{dy}{dx}=0+1.5-0\\\dfrac{dy}{dx}=1.5[/tex]
Therefore, the rate of change of cost with respect to the number of miles is 1.5 dollars per mile.

mariana wants to put 6 3/4 feet of border across the top of a wall she has 3 6/7 feet of border. what fraction of the project can she complete
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Length of the border Mariana wants to put across the top of a wall = [tex]6\frac{3}{4}[/tex] feet
= [tex]\frac{27}{4}[/tex] feet
If she has the length of the border = [tex]3\frac{6}{7}[/tex] feet
= [tex]\frac{27}{7}[/tex] feet
Therefore, fraction of the project can be completed = [tex]\frac{\frac{27}{7}}{\frac{27}{4} }[/tex]
= [tex]\frac{27}{7}\times \frac{4}{27}[/tex]
= [tex]\frac{4}{7}[/tex]
Fraction of the project can be completed = [tex]\frac{4}{7}[/tex]

A particular rocket taking off from earths surface uses fuel at a constant rate of 12.5 gallons per minute. The rocket initially contains 225 gallons of fuel
Answer:
Y=12.5x+225
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initially contains 225 gallons of fuel determine a linear model and Y equals X plus B form for the amount of fuel Y as a function of the number of minutes x at the rocket has burned
We were told to determine a linear model, where Y equals X plus B form for the amount of fuel Y as a function of the number of minutes x at the rocket has burned.
If we interpret this we have, Y=X+B , this equation can be compared to the standard equation of slope intercept of
Y= mx+b
Where the m is the slope, and b is the initial value at "y" intercept.
From the question, we were told that Y denotes a function of the number of minutes x at the rocket has burned
The given slope from the question, which is the rate= 12.5 gallons per minute
The given initial value =225 gallons of fuel which the value of "b"
If we substitute into the equation of the slope, we have;Y=12.5x+225 which is the required linear model .

He Hernández family is going to a swim meet. They bought 2 cases of water for $3.98 each, 3 bags of ice for $1.99 each, and a bag of oranges for $8.89. Before they leave, they filled up the car with 38.63 liters of gasoline at a cost of $0.655 per liter. What is the total cost for everything before tax?
Total cost of water, w =$ 3.98×2 = $7.96 .
Total cost of ice, i = $ 1.99×3 = $5.97 .
Total cost of orange, o = $8.89 .
Total cost of gasoline , g = $38.63×0.655 = $25.30 .
Now, total cost is the summation of every cost mention above :
T = $ ( 7.96 + 5.97 + 8.89 + 25.30 )
T = $48.12 .
Therefore, total cost for everything before tax is $48.12 .
Hence, this is the required solution.
