Answer:
f(3) = 3
Step-by-step explanation:
f(x) = (1/7)(7x)
f(3) = (1/7)(7×3)
f(3) = (1/7)(21)
f(3) = 3
There are multiple ways that you could graph this quadratic equation.
I would start by finding the vertex. The x-value in the vertex is found with -b/2a. The take you value and input back into the equation to find the y-value of your vertex.
Then, you could make a list of points on both sides of the vertex to create a table with which to create the parabola.
Answer: −18x+4
Step-by-step explanation:
=(−6)(3x+ −2/3)
=(−6)(3x)+(−6)(
−2/3)
I see you accidentally pasted the expression 2(4x-3)+3x-1 twice, so
expand 2(4x-3) to get
2(4x)+2(-3)=8x-6
now we have
8x-6+3x-1
regrouping we get
8x+3x-6-1
adding like terms
11x-7
A is 11x-4, not 11x-7, wrong
B is wrong
C. hmm, 6x-6+5x-1=11x-7, yep
D is the same, we can see
C and D are correct
You must go to the water park for 8 days to make buying the season pass worth it.
<em><u>Explanation</u></em>
Suppose, the number of days you must go to the water park is
Admission for the park is 17.50 per day. So, <u>the total cost for days</u> will be:
Given that, the season pass cost 125. So, the equation will be.....
<em>(As the number of days can't be in decimal)</em>
So, you must go to the water park for 8 days to make buying the season pass worth it.
