It will take 2 minutes because if you divide 700 by 10 you get 70 then 140 divided by 70 equals 2
A quadratic function:
First, take the point (0,-4) and plug the values (x,y) into the equation:
So the equation is
.
Now plug the values of the other two points into the equation and set up a system of equation:
The function is:
Answer:
In one hour Stephanie earns $1.50 more than Marco
Step-by-step explanation:
w=9h
H is a variable
9×hour= wage
9×15= $135
9×18= $162
157.50-135=$22.50
189-162=$27
27-22.50=4.50
Now cause its per hour we know she earns $4.50 more in 3 hours.
4.50÷3=$1.50
