<span>Twice the sum of x = 2x
2x </span>≤ 38
x ≤ 38 ÷ 2
x ≤ 19
Greatest value of x is 19
Answer:
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
Step-by-step explanation:
In simple terms, the domain of a graphed function refers to all the possible x-values while the range refers to all the possible y-values. Therefore, based on the graph the answer would be.
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
This is because x is in a slope and extends infinitely both to the left and to the right, therefore having all possible values. The y-axis starts at and includes the value 2 and all values less than 2. A black filled in dot in a graph indicates that the value is included.
Answer:
1) 8 2) 125 3) 1,680 4) 5,040 5) 3,024
Step-by-step explanation:
Answer:
3
Step by Step:
Subtract the tip ($6) from the total ($39)
11x=33
Then divide 33 by 11, leaving you with the value of x.
x=3
