The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake
Step-by-step explanation:
I'm guessing you live somewhere in the U.S. so I'll use the equation you use there
Equation:
[tex]y = mx + b[/tex]
[tex]m = \frac{y1 - y2}{x1 - x2} [/tex]
first pick two points
I'll pick (0,8) and (1,1)
[tex]m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7[/tex]
this means that the slope is -7
So far the equation will look like this
[tex]y = - 7x + b[/tex]
to get b pick one point, I'll pick (0,8) and replace y and x
[tex]8 = - 7 \times 0 + b[/tex]
when you solve this you'll get b
[tex]b = 8[/tex]
So the equation will look this
[tex]y = - 7x + 8[/tex]

A restaurant starts with 10 dozen
pieces of cornbread. Every order
receives 2 piece of cornbread. At the
end of their lunch rush, there are 28
pieces of cornbread left. How many
orders did the restaurant take?
Answer:
48 orders
Step-by-step explanation:
so 10 dozen is 120 because 12(10) is 120. we first subtract 120-28, which is 96. divided 96 by 2 to get 48.
equation: (12(10)-28)/2=x
Answer:
46 orders.
Step-by-step explanation:
(10*12) - 2x = 28
120 - 2x = 28
-2x = 28 - 120
-2x = -92
x = -92/2
x = 46

Answer:
The commission Mrs.Jones gets is 14000 dollars
Answer:
$14,000
Step-by-step explanation:
First, convert the percentage to a decimal and get 0.07. Multiply this by 200,000 and get 14,000. So 7% of 200,000 is 14,000.

Find the measure of each angle indicated
Answer:
C) 114
Step-by-step explanation:
41 + 73 = x
114 = x
In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?
A. 32
B. -32
C. 5
D. 24
Answer:
D. 24
Step-by-step explanation:
Plug in -14 to the equation:
f(x) = 2x - 4(x + 1)
f(-14) = 2(-14) - 4(-14 + 1)
Simplify:
f(-14) = -28 - 4(-13)
f(-14) = -28 + 52
f(-14) = 24

The cost of dinner for Lorenzo and his 3 friends was $45.96.
Part A. How much did each person pay if they shared the cost equally?
Part B. Write an equation to model the solution to the problem.
Enter the correct answers in the boxes.
A. $ =
B. Equation =
Answer:
The friends split the bill at 15.32$
Step-by-step explanation:
So to find how much each paid you would take the bill total and divide it by the amount of people in this case three
And for the equation it would be 45.96/3=15.32$
The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
Given that the dinner for Lorenzo and his 3 friends costs $45.96.
To determine how much each paid would take the bill total
Therefore, we will divide it by the number of people in this case three
3x = 45.96
x = 45.96/3
x = 15.32$
And for the equation would be; 3x = 45.96

A satellite radio company charges a one time fee of $36 for installation. The company also charges $42 per month for use. based upon this information complete this table showing the total cost of using the satellite radio after each month listed.
Answer:
Table shown below
Step-by-step explanation:
Linear Modeling
It consists of finding and using the equation of a line to represent the behavior of a real situation in numerical terms.
We are given the model of the charges for a satellite radio company that charges a fixed fee of $36 for installation and a variable fee of $42 per month for use.
The model is written as:
C(m) = 36 + 42m
Where m is the number of months.
For m=1:
C(1) = 36 + 42(1)=$78
For m=2:
C(2) = 36 + 42(2)=$120
For m=3:
C(3) = 36 + 42(3)=$162
For m=4:
C(4) = 36 + 42(4)=$204
For m=5:
C(5) = 36 + 42(5)=$246
