determine the values of X for which g(x) is defined
Answers
Answer: Any real number x as long as [tex]x \ne 0[/tex] and [tex]x \ne -\frac{2}{3}[/tex]
In other words, anything but 0 or -2/3 is valid.
========================================================
Explanation:
Set the denominator equal to zero and solve for x
2(3x^2 + 2x) = 0
3x^2 + 2x = 0
x(3x + 2) = 0
x = 0 or 3x+2 = 0 .... zero product property
x = 0 or 3x = -2
x = 0 or x = -2/3
If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x) will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.
Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.

Answer: x = 8/4 = 2
12(2) + 4(6) = 24 + 24 = 48 = 6*8
Step-by-step explanation:
$12X + $6(4) = (X+4)*$8
12X + 24 = 8(x+4)
12x + 24 = 8x + 32
12x + 24 - 8x - 32 = 0
4x - 8 = 0
4x = 8
x = 8/4 = 2

Answers
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]
So, the change in temperature is 3.25 degrees/hour.
Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25
