Properties:
1) a+ b = b+a Commutative
2) (a + b) + c = a + (b+c) Associative
3) a(b+c) = ab + ac Distributive
Here we are given
11 + (19 + 6) = (11 +___) + 6
The number 19 is missing on the right.
So we have
11 + (19 + 6) = (11 +19) + 6
This looks like Property 2 above.
Hence it is associative property.
Test a pair from each table by substituting their values into the given equation and solving.
A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1
B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1
C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1
D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1
The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.
Answer:
11
Step-by-step explanation:
The root of this parabola are x'=2 & x'' = 4, these are the value of x intercepts. The midpoint = (4-2)/2 = 1
