Sheryl earns about 13$ an hour so what you have to do is multiply 13 by 9 and then if I’m correct then that answer should land somewhere on the Line drawn
The answer is 7^12
This is because since they both have the same base, you just have to subtract the powers.
Answer:
See below for answers and explanations (along with a graph)
Step-by-step explanation:
<u>Part A</u>
Set f(x)=0 and factor the expression by grouping:
Use the Zero Product Property to find the x-intercepts:
Hence, the x-intercepts for the graph of f(x) are 
and 
.
<u>Part B</u>
Find the x-coordinate of the vertex:
Find the y-coordinate of the vertex:
Hence, the vertex is 
. We can see from the positive leading coefficient of the function that the vertex will be a minimum because the parabola will open faced-up.
<u>Part C</u>
You can use the x-intercepts and vertex to plot points of the graph of the function. Additionally, you can throw in the y-intercept in as well. The y-intercept, in this case, is 
, or 
as an ordered pair. See attached graph.
Answer:
Step-by-step explanation:
Salary offered to Emily after college = $35000
Rise in her salary = $2000 every year
Let she works for x years in the company,
Salary rise in her salary = $2000x
Total salary after x years = $(35000 + 2000x)
The independent variable x represents NUMBER OF YEARS and dependent variable is the TOTAL SALARY,because the SALARY depends on the NUMBER OF YEARS WORKED.
A function these variables is C(x) = 35000 + 2000x
So, C(4) = 35000 + 2000(4) = 43000, meaning 4 years later Emily will earn a salary $43000.
Answer:
b) -2
Step-by-step explanation:
The equation is in the form
y= mx+b where m is the slope and b is the y intercept
y = -x-2
The slope is -1 and the y intercept is -2
