Let f(x) = x++ pr'+ qx + 5 where p, q are constants. The remainder when f(x) is divided by (x + 1) is 7, and the remainder when f(x) is divided
by (x - 2) is 1. Find the value of p and the value of q.

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

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
