I think it is $60 per day
Do -4 times 3.2 and then do the same thing plzzz help me with a question now plzzz I all give you 100 points
Answer:
(-4, 5)
Step-by-step explanation (work shown in attached picture):
1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.
2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.
Since x = -4 and y = 5, the solution is (-4, 5).
Answer:
392 students
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
y is the number of students at the school
x is the number of years
r is the rate of change
a is the initial value
we have
substitute
For x=5 years
substitute
