Answer:
If simplifying, then
x^3 -13x^2 -x -49
Step-by-step explanation:
To do this, I would start off with the left side (use PEMDAS)
Use FOIL (First, Outside, Inside, Last)
x^3 + -9x^2 + 6x + -54 - (4x^2 + 7x - 5)
Bring negatives inside parenthesis
x^3 -9x^2 +6x -54 -4x^2 -7x +5
Combine like-terms
x^3 -13x^2 -x -49
(x^2 +6)(x-9)-(4x^2 +7x-5)
x^2 + 6 * x - 9 - 4x^2 - 7x + 5
x^2 + 6x - 9 - 4x^2 - 7x + 5
(x^2 - 4x^2) +(6x - 7x)+(-9 + 5)
(-3x^2)+(-x)+(-4)
=-3x^2 -x - 4
A parking meter at a parking garage charges $4 per hour. Every fraction of an hour is rounded up to the next hour. What is the cost for parking a car in the parking garage for 312 hours
Answer:
$1,248.00, or 1,248 dollars.
Step-by-step explanation:
First, multiply 4, which is the dollars per hour, by 2, which is 8. Then, multiply four with ten, which is 40. Next, multiply 4 with 3, which is 12, and add two zeros on the back, which is 1,200. Finally, add them all together for a total of $1,248.00, or 1,248 dollars.

In a scale model of the Eiffel Tower, 10 centimeters represent 65 meters. If the real Eiffel Tower is approximately 325 meters tall, how tall is the plastic model?
Answer:
The plastic model is 50 meters tall
Step-by-step explanation:
Here, we want to know how tall is the plastic model
In the plastic model 10 m represents 65 meters
then x meters plastic = 325 m real
10 * 325 = 65 * x
3250 = 65x
x = 3250/65
x = 50 meters

Linear function f is shown in the graph. Write the slope-intercept form of the equation representing this function.
The equation representing the function f(x) -
y = 4x - 8
We have a linear function f(x) as shown in the graph.
We have to determine the slope-intercept form of the equation representing this function.
What is the Slope - intercept form of the equation of a straight line ?The Slope - intercept form of the equation of a straight line is as follows -
y = mx + c
where -
m - slope of line
c - intercept of line on y - axis.
According to the question, we have -
c = - 8 = intercept of line on y - axes.
Intercepting coordinates on y - axes = (0, -8).
Intercepting coordinates on x - axes = (2, 0).
Slope = m = [tex]\frac{-8-0}{-2 -0}[/tex] = 4
Therefore, the equation representing the function f(x) -
y = 4x - 8.

Answer:
The value of m is 5/3 .
Step-by-step explanation:
=> 9m -4 = 6 + 3m.
=> 9m - 3m = 6 + 4.
=> 6m = 10.
=> m = 10/6.
=> m = 5/3 .

I used a graphing calculator to find the answer to your problem.
The graph shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled. PART A What is the unit rate for each machine? PART B Which machine can fill cartons at a faster rate? How much faster?
Answer:
A. 25, 22
B. machine 1
How much faster? MACHINE 1 fills 3 more cartons per minute than MACHINE 2
Step-by-step explanation:
Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled.
The equation of the graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill is -
y = [(100 - 50)/(4 - 2)]x
y = 25x
AND
y = 22x describes the rate at which Machine 2 can fill cartons.
So, we can write -
Machine 1's unit rate = 25
Machine 2's unit rate = 22
It is easily visible that Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.
Therefore,
Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

What are the points for y=-3x+4 and how do I graph it
Answer:
(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8) are your graph points.
Step-by-step explanation:
Okay so to find the points, you have to create a table graph with a set of x values.
in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.
-3(-3)+4= 13
-3(-2)+4= 10
-3(-1)+4= 7
-3(0)+4= 4
-3(1)+4= 1
-3(2)+4= -2
-3(3)+4= -5
-3(4)+4= -8
Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!
