Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
75% of students = 18
Divide by 3 to find 25% of students.
25% of students = 6
Add the two together or multiply the 25% of students by 4 to get the total number of students.
25% + 75% = 6 + 18 = 24 students
or
25%*4 = 6*4 = 24 students
Answer:
The function f(x) was translated right 3 units and up 2 units.
Step-by-step explanation:
F(x)=(2/3)^x
If we move it right for 3 units, we get
f(x)= (2/3)^(x-3)
If we move up 2 units , we get
g(x)= (2/3)^(x-3) +2
Answer:
0 and 2
Step-by-step explanation:
To find zeros set f(x)=0 and solve for x
now factor out x
set each factor =0 and solve for x
no solution for x
zeros of f are 0 and 2
