2x+2y=4
-2x from both sides
then you get 2y=2x+4
Divide 2x+4 by 2 and you get y=x+2
5 1/9 rounds to 5
1 7/8 rounds to 2
5+2 = 7
11/20 rounds to 1
5/8 rounds to 1
1-1 = 0
8/9 rounds to 1
2 13/15 rounds to 3
1+3 = 4
22 - 3b = 7
Subtract 22 from both sides:
-3b = -15
Divide both sides by-3:
B = 5
Answer: 3π in terms of pi or 9.42 if in π or pi= 3.14
Step-by-step explanation:
Answer:
f(x) = x² + 2x - 3
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1
Thus the factors are (x + 3) and (x - 1) and
f(x) = (x + 3)(x - 1) ← distribute using FOIL
= x² - x + 3x - 3
= x² + 2x - 3
