Answer: x>1
Step-by-step explanation:
To solve for x, we want to isolate x.
3x+7>10 [subtract both sides by 7]
3x>3 [divide both sides by 3]
x>1
Therefore, we know that x>1.
The board length that will be bought is 4.438 feet
Since the board will be cut into 3 pieces. From the information given in the question, the lengths of the board will be:
= 1.4 feet + 1.4 feet + (1.17 × 1.4 feet)
= 1.4 feet + 1.4 feet + 1.638 feet
= 4.438 feet
In conclusion, the board length that should be bought is 4.438 feet.

Answer: Choice B) { f(x)| –∞ < f(x) ≤ 4}
Note that { f(x)| –∞ < f(x) ≤ 4} is the same as { f(x)| f(x) ≤ 4} and that's saying "the output y is at most 4". So the largest y can get is 4. This is the upper limit or ceiling so to speak. The value of y can be any number less than 4.
The range is basically the set of all possible y outputs of a function. It is the set of all y coordinates of the points on the function curve. The highest we can go is y = 4. There is no limit on how low the points can go, so it goes off to negative infinity.
