Answer:
D = 30*T, where D is the distance in miles and T is the time in seconds
Step-by-step explanation:
The speed of the powered scooter is 30 miles per second, so for each second, her distance will be 30 miles.
With that information, we can formulate an equation that shows her distance with relation to time:
Let's call her distance D, and the time she is traveling T
if in one second she travels 30 miles, in T seconds she will travel 30*T miles, and that is the distance she travelled, so the equation is:
D = 30*T.
Answer:
which 1st page or 2nd page
In the notation "s(x) = ...," what does "s(x)" represent?
It represents the output or y of the function of x.
S(x)=2x
S(2)=2(2)=4
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
