Answer:
0
Step-by-step explanation:
Isolate the variable x. First, distribute 3 to all terms within the parenthesis.
3(2x + 3) = 3(2x) + 3(3) = 6x + 9
6x + 9 = 9
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.
6x + 9 (-9) = 9 (-9)
6x = 0
Divide 6 from both sides.
(6x)/6 = (0)/6
x = 0
0 is your answer.

Answer:
A. Between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either
goes from a negative value to a positive value or vice versa.
From
and
, the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.
From
and
, the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.
Answer: C) F(4) = 0
Detailed Explanation:
A zero/root of a polynomial is a value of the variable which makes the value of the polynomial to 0.
Therefore, when (x - 4) is a Factor :-
=> x - 4 = 0
=> x = 4
=> x = 4 is the Zero of the Polynomial.
A linear equation has 1 for all exponents on the placeholders
aka the equation is first degree (aka the hightest exponent on placeholders=1) so
it is linear
