<span>g(f(x)) = g(-5x+4) = 4(-5x+4) + 5 = 21-20x</span>
Answer:
Below.
Step-by-step explanation:
2x+4 = (x²)²÷2
2x + 4 = x^4/2
x^4 = 4x + 8
x^4 - 4x - 8 = 0
We can try trial an error to solve this
Looks like x = 2 fits it:
2^4 - 4(2) - 8
= 16 -8 -8 = 0
so x = 2 is one solution.
I can't find any other solution among other integers.
To find the other solutions you can draw a graph manually or by using software.
There will be either 1 or 3 more real solutions.
I used software to draw the graph and found one other solution:
x = -1.296
A) Let x = number of presale tickets
<span>y = number of day of show tickets </span>
<span>x + y =< 800 </span>
<span>6x + 9y >= 5000 </span>
<span>b) 6x + 9y >=5000 </span>
<span>6(440) + 9y >=5000 </span>
<span>y >= 262.2 </span>
<span>263 tickets </span>
<span>440 advance purchase tickets added to 263 day of show tickets is 703 tickets, which is below the 800 ticket maximum.</span>
Answer:
(a). 7√2
Step-by-step explanation:
I think it’s x = 9 hope it helps :D
