Answer:
Third choice
Step-by-step explanation:
They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)
y=5x
x=5y (I switch x and y)
x/5=y ( I divided both sides by 5)
Then you just replace y with the f^-1(x) thing
f^-1(x)=x/5
or
f^-1(x)=1/5x
Answer:
Like electric charges repel each other. ... Why can't conductors generate static electricity when rubbed together? They will direct excess charge to earth. Suppose you acquire a positive charge from walking across a carpet.
Answer:
150
Step-by-step explanation:
You would divide the distance (1440) by how much he would go each day (9.6) and the answer is the amount of days
1440÷9.6=150
Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.
Answer:
