Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E() = 10x- 35, where xis the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
What does the slope of Jessica's function represent?
Answers
Answer:
A you can check it by substituting values into x like 5 and 6 then compare the E(X) value
The solution is :
The slope represents the rate of change of earnings in a week for every unitary change in number of doors knocked. For Jessica's function, her earnings change by +7 units for every unit of door she knocks.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
The slope of any linear function tells us the rate of increase in Y given 1 unit increase in X
[note the equation as y = mx+b ].
Here, m is the slope.
Jessica's weekly earning function is:
E(x) = 7x - 25
Where,
E(x) is her weekly earnings
x is the number of doors she knocks
So, when comparing this to the meaning of slope stated above, we can say that the slope of Jessica's function represents the rate of change of earnings in a week for every unitary change in number of doors knocked.

Step-by-step explanation:
Given
Rule:
Output = Input + 3
Required
Complete the table
Represent the input with x and the output, y
So, the rule becomes
[tex]y = x + 3[/tex]
When Input = 1
[tex]x = 1[/tex]
[tex]y = x + 3[/tex]
[tex]y = 1 + 3[/tex]
[tex]y = 4[/tex]
This means:
Output = 4
When Input = 6
[tex]x = 6[/tex]
[tex]y = x + 3[/tex]
[tex]y = 6+3[/tex]
[tex]y = 9[/tex]
This means:
Output = 6
When output = 11
[tex]y = 11[/tex]
[tex]y = x + 3[/tex]
[tex]11 = x + 3[/tex]
[tex]x = 11 -3[/tex]
[tex]x = 8[/tex]
This means
Input = 8
So, the complete table is:

Answers
Answer:
A sandwich costs $7.5
Step-by-step explanation:
Given
Represent chips with c and sandwiches with c
[tex]c = \$1.25[/tex]
[tex]Total = \$38.75[/tex]
From the question, we understand that 5 sandwiches were ordered.
Hence, the question of the system is:
[tex]5s + c = Total[/tex]
Substitute values for Total and c
[tex]5s + 1.25 = 38.75[/tex]
Collect Like Terms
[tex]5s = 38.75 - 1.25[/tex]
[tex]5s = 37.5[/tex]
Divide both sides by 5
[tex]s = \frac{37.5}{5}[/tex]
[tex]s = 7.5[/tex]

Answer:
The mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs.
Step-by-step explanation:
This questions implies that there is a need to fill in mathematical symbols that will this a true a equation.
A true equation can be described as situation whereby there the same values on the either sides of the equal sign "=". For instance, 5 + 1 = 6 is a true equation. Also, 4 * 2 = 8 is a true equation.
As regards this question, the mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs. When the multiplication signs are filled in between the numbers, we have the following true equation:
2802 * 1811 * 123 * 441 * 3633 * 1/3 * 32^2 * 205 = 69,972,637,305,761,000,000

2 Cassie has a family photograph that measures 5-inches wide and 7-inches long. She wants to enlarge the photograph and hang it on the wall. If the length of the enlarged photograph is 87.5 inches, what is the width of the enlarged photograph?
Answers
Answer:
62.5 inches
Step-by-step explanation:
We would solve this using ratio
Width : Length = Width/Length
For the Original photo
5 inches : 7 inches = 5/7
For the enlarged phots
x : 87.5 inches = x/87.5
Equating both ratios together, we have:
5/7 = x /87.5
Cross Multiply
7x = 5 × 87.5
7x = 437.5
x = 437.5/7
x = 62.5 inches
Hence, the width of the enlarged photo is 62.5 inches
