Rate of change is -2 because you can do rise over run to find the constant rate of change, and since you are going down you have a negative slope.
Answer:
59
Step-by-step explanation:
3^3=27
2x27=54
27+54+5=59
Answer:
x=0 and y=4 thats where the points meet
Step-by-step explanation:
solution of x and y:
both equations equal to y so you can put them together
3/5x+4=-x+4
separate the variables and numbers...
1.6x=0
x=0
y=4
if ur using a graph, use the y intercept (0,4) for your first point
then, using y=-x+4, make -x a fraction -1/1
by using rise/run go down one unit from (0,4) since its negative 1
then one unit to the right from where you are
you should be able to connect the points for the first equation
find the second equation on your own now:)
If she can go 35 miles with 1 gallon, and 1 gallon costs $2.56, all you need to do is divide $2.56 by 35 to get the cost per gallon.
