Answer:
It's A, c =2.5d
Step-by-step explanation:
When it comes to problems like this, I usually look through the answers and try to plug in the numbers until I get the right equation that fits with the graph.
2.5(5) = 12.5
2.5(10)= 25
2.5(15)= 37.5
2.5(20) = 50
2.5(25) = 62.5
If you compare this to the graph, you'll notice the solutions are the same as the Total Cost (c). That's because c= 2.5d is the right equation for this graph. (Sorry if my explanation is confusing)
Answer:
the correct volume is 120in.3
Step-by-step explanation:
he did his math wrong, 20 x 6 is not 26.
V = 5 x 4 x 6 = 20 x 6 = 120
The given system of equation that is 
and 
has infinite number of solutions.
Option -C.
<u>Solution:</u>
Need to determine number of solution given system of equation has.
Let us first bring the equation in standard form for comparison
To check how many solutions are there for system of equations 
, we need to compare ratios of 
In our case,
As 
, so given system of equations have infinite number of solutions.
Hence, we can conclude that system has infinite number of solutions.
The correct answers among all the other choices are A) Addition, B) Subtraction, C) Multiplication, and D) Division. These mathematical operations can be used with functions. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Step-by-step explanation:
You want the to find the value of k such that the y coordinate of the vertex is 0.
0=x2−6x+k
The x coordinate, h, of the vertex is found, using the following equation:
h=−b2a
h=−−62(1)=3
Evaluate at x = 3:
0=32−6(3)+k
k=9
