A catering company sells an 8 lb container of food for $54. Use a model to write a rate for this situation. What does this rate mean?
Answer:
$6.75 per pound
Step-by-step explanation:
$54 ÷ 8lb = $6.75/lb
or a 1:6.75 ratio/rate
The model to write the rate for this situation is 54 / 8 and the rate is $6.75.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity.
Given that,
A catering company sells an 8 lb container of food for $54.
We have to find the unit rate for the given situation.
Price for 8 lb container of food = $54
Price for 1 lb container of food = 54 / 8
= $6.75
This is the required rate, which means that price for 1 lb container of food is $6.75.
Hence, the unit price for the food sold by catering company is $6.75.

The value of x is 7.
The value of x is -1/4.
The value of x is 7.
The value of x is 4 1/3.
The value of x is -5.
The value of x is 0.
What is the value of x in the equations?2(2x + 1) = 30
The first step is to divide both sides of the equation by 2
2x + 1 = 15
Combine similar terms
2x = 15 - 1
2x = 14
x = 7
3(4x - 3) = -12
The first step is to divide both sides of the equation by 3
4X - 3 = -12 /3
4x - 3 = -4
Combine similar terms
4x = -4 + 3
4x = - 1
x = -1/4
4(2x - 7) = 20
The first step is to divide both sides of the equation by 4
2x - 7 = 5
Combine similar terms
2x = 5 + 7
2x = 12
x = 6
7(3x - 4) = 63
The first step is to divide both sides of the equation by 7
3x - 4 = 9
Combine similar terms
3x = 9 + 4
3x = 13
x = 4 1/3
6(3x + 3) = -72
The first step is to divide both sides of the equation by 6
3x + 3 = - 12
Combine similar terms
3x = -12 - 3
3x = -15
x = -5
-2(6x - 3) = 6
The first step is to divide both sides of the equation by -2
6x - 3 = -3

Step-by-step explanation:
Given the following question:
[tex]x+\frac{2}{3} =\frac{9}{10}[/tex]
In order to find the answer to this question we need to subtract 9/10 from 2/3. To do this we need to find the common denominator, and then subtracting the numerators.
[tex]\frac{9}{10} -\frac{2}{3}[/tex]
[tex]\frac{9}{10} \times3=\frac{27}{30}[/tex]
[tex]\frac{2}{3} \times10=\frac{20}{30}[/tex]

linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4
Answer:
y = -4x + 14
Step-by-step explanation:
We'll use the slope intercept form: y = mx + b
It is given that the slope of -4, so m will be -4 like this: y = -4x + b
We are also given the coordinates where x = 3 and y =2
2 = -4(3) + b
2 = -12 + b
Add 12 to both sides
2 = -12 + b
+ 12 + 12
b = 14
We end up with y = -4x + 14

During a winter storm, the temperature on the top of a
mountain changed an average of -2.5°C every hour
for 12 hours. At noon, the temperature was -5°C.
During the same time period, the temperature at the
bottom of the mountain changed at the rate of
temperature change on the top of the mountain.
What is the hourly rate of temperature change at the bottom of the mountain ?
According to the rate of change, it is found that the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
What is the average rate of change?
The average rate of change of a function is given by the change in the output divided by the change in the input.
In this problem, it is stated that at the top of the mountain, the average rate of change is of -2.5 ºC per hour, and at the bottom of the mountain the rate is the same, hence the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.

Write an equation for the function graphed below. I keep doing this and getting the same answer, what am I doing wrong.
Answer:
(-4(x-2))/((x+2)|(x-4)|)
Step-by-step explanation:
You were so close. I stared at your problem for a
long time when you first posted it. I used a graphing utility to experiment. Your denominator was perfect for getting the vertical asymptotes in the right place. The y-intercept worked. The x-intercept was exactly right. I couldn't get the far right piece of the curve to reflect down in the fourth quadrant.
Hours later...suddenly BAM! ABSOLUTE VALUE pops into my head.
I always thought the numerator should be negative, so that middle portion of the curve that looks like a cubic would start "up to the left" and end "down to the right" But those left and right curves should be like mirror images of each other sort of. So I tried the absolute value and it worked! Good luck with your work. Hope this helps a little.
Please help, I need 8 through 10.
Which of the graphs below would result if you made the leading term of the
following function negative?
F(x) = x^3 + 3x^2
Answer:
D
Step-by-step explanation:
Cubic equation: an algebraic equation of degree three and of the form
[tex]ax^3 + bx^2 + cx + d = 0[/tex], where a, b and c are the coefficients and d is the constant.
If the leading coefficient [tex]a[/tex] of a cubic equation is positive, the curve begins in quadrant III and ends in quadrant I
If the leading coefficient [tex]a[/tex] of a cubic equation is negative, the curve begins in quadrant II and ends in quadrant IV
For information
Graph A = cubic function with positive leading coefficient
Graph B = quadratic function with positive leading coefficient
Graph C = quadratic function with negative leading coefficient
Graph D = cubic function with negative leading coefficient
Therefore, if you made the leading coefficient of [tex]f(x)=x^3+3x^2[/tex] negative, it would be graph D.
