Answer:
Its the second option:
f(x) = (x + 3)(x - 1)(x - 4).
Step-by-step explanation:
As it passes through x = -3 that is one root so one factor is (x + 3).
As it also passes through x = 1 another factor is (x - 1).
Also as it passes through x = 4 the third factor is (x - 4).
Given that Antonia and Carla have the same percentage of marbles and Antonia has 4 green marbles out of 16 marbles , to calculate the number of marbles that Carla has that aren't green we proceed as follows;
let the total number of Carla's marbles be x;
the percentage of green marbles that Antonia has is:
4/16×100=25%
since they have the same percentage then:
number of green marbles Carla has is 10:
this is 25% of x, hence:
10/x×100=25
1000/x=25
1000=25x
thus
x=1000/25
x=40
Carla has a total of 40 marbles. Thus the number of marbles which are not green will be:
40-10=30 marbles
Answer:
Equation
28 = X - 12
Solve for X
Isolate the X
28+12 = X
40 = X
