step-by-step explanation:
i'm assuming you need to figure out how many campers go into each tent.
i got the answer by:
24+4=28
28/4=7
x = -3
y = -18
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
the height of the surface increases from the center out to the sides of the road
it is c!
write out the polynomial, with leading coefficient 1:
y = 1 (x+2)^1 (x-7)^1 (x-5)^2
