Which statement is true about the solutions for the equation 3y + 4 = −2?
2 answers:
Answer:
1. It has one solution.
2. It has no solution.
Step-by-step explanation:
1.
The given equation is
Subtract 4 from both the sides.
Divide both sides by 3.
Therefore this equation has only one solution.
2.
The given equation is
Subtract both sides by (5n-3).
LHS is not equal to RHS for any value of n, therefore this equation has no solution.

Answer:
(g-f) (-1)= sqrt(15)
(f/g)(-1)= 0
(g+f)(2)=sqrt(3)-3
(g*f)(2)=-3*sqrt(3)
Step-by-step explanation:
We have to eval the expressions given in the point indicated.
Lets start by the first equation
(g-f)(-1)= g(-1) - f(-1)= =
Now, lest continue with the others
(f/g)(-1)= f(-1)/g(-1)= (1-1)/sqrt(15)=0
(g+f)(2)=g(2)+f(2)=sqrt(3)-3
(g*f)(2)=g(2)*f(2)=sqrt(3)*(-3)=-3sqrt(3)
