The set of all possible values of the independent variable of a function is called the domain.
The set of all possible values of the dependent variable of a function is called the Range .
<u>Note</u>. Two things completely determine a function: the rule and the domain.
Answer:
Is x = 4 a solution to the equation 6 = x + 2? YES
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Step-by-step explanation:
Is x = 4 a solution to the equation 6 = x + 2? YES
we cans solve the equation 6=x+2 by clearing for x:
6 = x + 2
we move the +2 on the right as a -2 to the left:
6 - 2 = x
4 = x
this way we find that indeed x = 4 is a solution to 6 = x + 2.
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Let's solve the inequality by clearing for x:
2x ≥ 9
we move the 2 that is multiplying on the left to divide on the right side:
x ≥ 9/2
x ≥ 4.5 ⇒ <u>x must be greater than or equal to 4.5</u>
thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5
10x6=60 so 180-60=120 and 120 divided by 8 is 15 so the answer is 15 hours
¾ + ¾ + ¾ + ¾ = (3+3+3+3)/4 = 12/4 = 3
¾ × 4 = (3 × 4)/4 = 12/4 = 3
7 tiles with plants and 2 tiles with animals...total of 9 tiles
she flips a plant tile, and does not replace it.
probability that 2nd tile is a plant = 6/8 = 0.75 = 75%
