First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18
4x-12.
4x/4-12/4. So x=3
The fours cancelled out
7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out
Answer:
B. 3a/a-2
Step-by-step explanation: according to e2020
Zeros are the x values which make the function equal to zero. Set it up as you would for a binomial with a constant multiplier "k" to account for the y-intercept (0, -5) given.
f(x) = k(x-2)(x-3)(x-5)
Use the y-intercept (0,-5) to solve for k.
-5 = k(0-2)(0-3)(0-5)
-5 = -30k
-5/-30 = k
1/6 = k
The cubic polynomial function is then ..
f(x) = (1/6)(x-2)(x-3)(x-5)
Linear factors are the linear (line) expressions you can factor out of the polynomial. They are (x-2), (x-3) and (x-5).
X > 50/-5
X>-10
The answer is B. :)
