The first step is to rewrite the equations given in the problem.
y = 2x - 2 → 2x - y = 2
y = 2x + 2 → 2x - y = -2
y = 2 - x → x + y = 2
y = 4 - x → x + y = 4
Then let u = 2x - y and v = x + y. Therefore we get the equations with the following bounds -2 ≤ u ≤ 2 and 2 ≤ v ≤ 4.
The question is asking 15+2*9=? so to do this first multiply 2*9 which = 18 and then add 15, 18+15= 33
Answer:
-2.02083333333
Step-by-step explanation:
1-3 is -2/4, and 6-3 is 3/8 so -1/2/3/8 is -1 and 1/3
1-23 is -22/32,or -11/16
-1 and 1/3 + -11/16 is -2.02083333333
