Answer:
D
Step-by-step explanation:
x+4y=8
4x+y=2
add
5x+5y=10
so system is
x+4y=8
5x+5y=10
25 girls and 50 boys!!
49 divided by 7 = 7.
So there were 7 adults.
49 + the 1 it mentioned = 50 boys
50 divided in half = 25 girls.
50+25+7 = 82.
The y axis for dependent variables and x axis for independent
Answer/Step-by-step explanation:
Total Distance = 3Ft
a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.
Amplitude = 3/2 = 1.5 period = 10 second
No ph. Shift
b) Write an equation of a function that models the buoy with x=0 at its highest point.
y= 1.5 cos (
