Answer:
ur right
it's -1013
bc you need to do multiplication first so the equation turns out to be
10 - 1000 - 23
so then that turns to -1013 if you calculate left to right
What did ur friend get???
Complex solutions, namely roots with a √(-1) or "i" in it, never come all by their lonesome, because an EVEN root like the square root, can have two roots that will yield the same radicand.
a good example for that will be √(4), well, (2)(2) is 4, so 2 is a root, but (-2)(-2) is also 4, therefore -2 is also a root, so you'd always get a pair of valid roots from an even root, like 2 or 4 or 6 and so on.
therefore, complex solutions or roots are never by their lonesome, their sister the conjugate is always with them, so if there's a root a + bi, her sister a - bi is also coming along too.
if complex solutions come in pairs, well, clearly a cubic equation can't yield 3 only.
Answer:
The value of this new equation would be (2x - 5)/6x.
Step-by-step explanation:
In order to find the value of this equation, we need to take the original equation and replace every x with (x - 1/x+2).
f(x)= 3x - 1/4x + 2
f(x)= [3(x - 1/x+2) - 1]/[4(x - 1/x+2) + 2]
f(x) = [(3x - 3/x + 2) - (x + 2/x + 2)]/[(4x - 4/x + 2) + (2x + 4/x + 2)]
f(x) = (2x - 5/x+2)/(6x/x + 2)
f(x) = (2x - 5)/6x
Answer:
24. x = 8.
25. x = -9, 10.
Step-by-step explanation:
The zeros of the functions are the solutions to the equation when y=0. To find the solution, factor each equation.
24. Look for two factors that multiply to 64 and add to -16. The factors are -8 and -8. Write them in binomial forms.
(x-8)(x-8)
So x = 8.
25. Look for two factors that multiply to -90 and add to -1. The factors are 9 and -10. Write them in binomial forms.
(x+9)(x-10)
So x = -9, 10.
Answer:
yo its not that hard it just means that it can be any number
