A number subtracted from five is equal to negative ten
Answer:
x=+/-3
Step-by-step explanation:
x^4-5x^2-36=0
factor
(x^2-9)(x^2+4)=0
split into 2 equations because one of these terms will need to equal zero for the eqation to be true
x^2-9=0 x^2+4=0
x^2=9 x^2=-4
x=+/-3 no real numbers
Answer:
42.43
Step-by-step explanation:
Since -3xy and negative 4xy are like terms, subtract 4xy from -3xy to get -7xy
-7xy is your answer
Answer:
The function notation is when we represent one of the coordinate points as a function of the other ones.
In the general case, we will have:
y = f(x)
Now, we have that:
y = 7*x - 2
Then the function notation will be:
y = f(x) = 7*x - 2
or simply
f(x) = 7*x - 2
