(28 * x) -42 = 154
28x - 42 = 154
28x = 196
the unknown number is 7
Make a graph and put a point at exactly (1,2) and then make a like at y=3 make a line through the point and you'll see that this is an undefined equation x cant equal all those numbers
Answer:
-22
Step-by-step explanation:
First do r(3) by replacing x with 3 in r:
2*3^2 + 2 = 2*9 + 2 = 18 + 2 = 20
Then replace r(3) with 20 to do q(20):
-20-2 = -22
