Which of the following is a parent function? A. f(x)=e^x
B. f(x) = 2e^2x
C. f(x) = 2•3^x
D. f(x) = x^4+3

the answer is 4.8 units on e2020.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
