What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of units of orange juice at beginning = 30 units
The number of units purchased = 50 units
Total units = 30 + 50 = 80 units
The number of units at the end = 30 units.
The number of units sold.
= Total units - Units at the end
= 80 - 30
= 50 units.
Thus,
The number of units sold is 50 units.

Solve the system of equations using substitution. y = -7x 2x – y = -9
Answers
Answer:
x = -1
y = 7
Step-by-step explanation:
We have a system of equations and are asked to solve using substitution.
y = -7x
2x - y = -9
Since we have an equation for y by itself, we can plug the first equation into the second.
2x - (-7x) = -9
Distribute :
(-(-7x))
2x + 7x = -9
Add like terms :
9x = -9
Divide 9 by both sides to get x :
x = -1
Now that we know x, we can plug it into the first equation to find y :
y = -7(-1)
y = 7

The revenue (in dollars) from the sale of x car seats for infants is given by the following function. R(x) =56x -0.020x^2 0less than or equal to x and 2800 is greater than or equal to x
Answers
Answer:
[tex]Rate = 15[/tex]
Step-by-step explanation:
Given
[tex]R(x) = 56 - 0.020x^2[/tex]
Required
Find the average change from 1,000 car seats to 1,050 car seats --- Missing information
This is calculated using:
[tex]Rate = \frac{R(b) - R(a)}{b-a}[/tex]
In this case:
[tex]a = 1000[/tex]
[tex]b = 1050[/tex]
Now, we have:
[tex]Rate = \frac{R(1050) - R(1000)}{1050-1000}[/tex]
[tex]Rate = \frac{R(1050) - R(1000)}{50}[/tex]
Calculating R(1050)
[tex]R(1050) = 56 *1050- 0.020*1050^2[/tex]
[tex]R(1050) = 58800-22050[/tex]
[tex]R(1050) = 36750[/tex]
Calculating R(1000)
[tex]R(1000) = 56 *1000- 0.020*1000^2[/tex]
[tex]R(1000) = 56000- 20000[/tex]
[tex]R(1000) = 36000[/tex]
So:
[tex]Rate = \frac{R(1050) - R(1000)}{50}[/tex]
[tex]Rate = \frac{750} {50}[/tex]
[tex]Rate = 15[/tex]
The average rate of change is 12
