For this case we define the following variable:
x: time it takes A to perform the job separately.
We then have the following equation:
From here, we clear the value of x.
We have then:
Therefore, the time it takes for B to complete the work is:
Answer:
B will spend 12 hours doing that work separately
One-to-one means the function will cross ANY horizontal or vertical line at at most one point.
Answer:
B
Step-by-step explanation:
5x + 2(x-3) = -2(x - 1)
1. Distribute 2 through the parentheses:
5x + 2x - 6 = -2 (x - 1)
2. Distribute -2 through the parentheses:
5x + 2x - 6 = -2x + 2
3. Collect like terms:
7x - 6 = -2x + 2
