Answer: g(-x) = 2x^2 +5x + 5
Step-by-step explanation:
This Is a topic under functions in mathematics, it deals with substituting "x" for the new entity that has been placed in the new function you're asked to look for.
Hence, to solve this, we simply substitute "-x" for "x" wherever "x" appears in the equation.
By doing so, we go straight to the given function.
2x^2 -5x + 5
And we go ahead with our substitution which goes thus:
2(-x^2) -5(-x) + 5
On simplifying, we then finally have have:
2x^2 +5x + 5.
This means:
g(-x) = 2x^2 +5x + 5
Number 6 is A because Five times -1 is -5+3×11 equal -2
Answer:
4
Step-by-step explanation:
This is a substitution question
So we will have to substitute the value of x given into the given question
f(x)=8^x
And x is given as 2/3
So let's get to work
8^2/3 which means that cube root of 8 then square the answer
(3√8)^2
Cube root of 8 is 2
So we will have to square 2 to get 4
Therefore the final answer is 4
I believe you understand
Answer:
19/50 = 38%
Step-by-step explanation:
19 out of 50 runners finished in fewer than 30 minutes so the fraction will be 19 (the number of runners that finished in fewer than 30 minutes) divided by 50 (the total number of runners) so you get 19/50 = 38/100 = 38%
It is y=-3.5+9.5
i dont know how to put it into fraction form sorry
