ashley has some pennies and some nickels. she has at most 22 coins worth a minimum of $0.78 combined. if ashley has 4 pennies, determine the minimum number of nickels that she could have. if there are no possible solutions, submit an empty answer.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
