Step-by-step explanation:
with your square root symbol I never know what is inside the square root and what is possibly outside.
so, I can only guess and see what comes close.
f(x) = 2x² + x - 1
g(x) = sqrt(2x - 1) ??? is that so ?
h(x) = -2
2g(f(x)) + h(x)
g(f(x)) means that the whole f(x) expression is used as x in g(x).
the whole combined function is then
2×sqrt(2(2x² + x - 1) - 1) - 2
2×sqrt(4x² + 2x - 2 - 1) - 2
2×sqrt(4x² + 2x - 3) - 2
and if I am not mistaken, then this is the solution you mentioned at the beginning (if I try to read between the typos and missing info).
this is how people get to this.
do you understand it now ? or is there still something unclear ?
Answer:
Should be 4/7
Hope it helps have a good day!
10=5×2 or 5×2=10 or 2×5=10 or 10=2×5
they're all the same thig but i'd probably go with 5×2=10 :)
Answer:
2/3
Step-by-step explanation:
You can simplify the fraction by dividing by 8, so 16/8=2 and 24/8=3, and 2/3 is the most simplified it can be, if you need more information on how I did this, I'll be glad to explain better :)
