Right now we have:
5kx + 6 = 7kx
First, divide both sides by k to eliminate that variable:
5x + 6 = 7x
Then subtract 5x from each side:
6 = 2x
Lastly, divide each side by 2 to solve for x:
3 = x
Hope this helps!
An inverse function reverses the roles of inputs and outputs (of x-values and y-values).
If (2,4) is on the graph of a function, then (4,2) is on the graph of the inverse function.
If (9,7) is on the graph of the inverse, then (7,9) would be on the graph of the original function.
If (a,b) is on the graph of the function, then (b,a) is on the graph of the inverse.
Getting to your question, which of the points listed has the inverse listed up in the table?
Answer:
Step-by-step explanation:
2,401 = 7^6 - 2x
2401 + 2x = 117649
2x = 117649 - 2401
2x = 115248
x = 115248 / 2
x = 57624
Answer: y = (x +2)² + 5
<u>Step-by-step explanation:</u>
y = a(x - h)² + k <em>where "a" is the leading coefficient and (h, k) is the vertex</em>
Since we don't know "a", we need to plug in the point (x, y) and the vertex (h, k) to solve for "a": (x, y) = (0, 9) and (h, k) = (-2, 5)
y = a(x - h)² + k
9 = a(0 - (-2))² + 5
9 = a(0 + 2)² + 5
9 = a(2)² + 5
<u>-5 </u> <u> -5 </u>
4 = a(4)
<u>÷4 </u> <u> ÷4 </u>
1 = a
Next, plug in "a" and the vertex (h, k):
y = a(x - h)² + k
y = 1(x +2)² + 5
y = (x +2)² + 5
Answer:
are there any options? if not then i think it's 360 ( sorry if i'm wrong)
