Step-by-step explanation:
Substitute variables with given values
Minus sign becomes plus sign if a negative is multiplied by a negative or a negative is put next to a negative number.
4x-7y=4(-5.2)-7(-6.8)
-20.8+47.6=26.8
The solutions to a function are the points where the graph of the function crosses the x-axis, but only if the solutions are real numbers. If the function has imaginary solutions, then you don't see those on the graph.
Answer:
2.25 feet
31.5 feet
Step-by-step explanation:
Given that the person travels 9 feet every 4 seconds, it means that in one second, the distance walked
= 9/4
= 2.25 feet
If the person walks 2.25 feet in a second then in 14 seconds, the distance walked
= 2.25*14/1
= 31.5 feet
