Answer:
480 students want more field trips.
60 students is 10%.
Step-by-step explanation:
There are 600 students, and 80% want more field trips.
80% of 600 is 0.8*600 = 8*60 = 480 students.
480 students want more field trips.
How many students is 10%?
10% of 600 is 0.1*600 = 60*1 = 60
60 students is 10%.
Function a: exponential function
Function b: linear function
Function c: exponential function
Answer:
y = - 23x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 23 and c = - 4, thus
y = - 23x - 4 ← equation of line
