Basically the graph of this, would simply be a horizontal line, where although the X values change, the y coordinate is the same for all of them.
For instance certain ordered points can be - (-1,4), (0,4), (1,4), (2,4) ...
Answer:
B and D
Step-by-step explanation:
To determine which point is a solution, substitute the x- coordinate into the right side of the equation and if the value obtained agrees with the y- coordinate then it is a solution.
(5, 10)
y = 5² - 2(5) + 1 = 25 - 10 + 1 = 16 ≠ 10 ← not a solution
(- 1, 3)
y = (- 1)² - 2(- 1) + 1 = 1 + 2 + 1 = 3 ← This is a solution
(1, 2)
y = 1² - 2(1) + 1 = 1 - 2 + 1 = 0 ≠ 2 ← not a solution
(3, 4)
y = 3² - 2(3) + 1 = 9 - 6 + 1 = 4 ← this is a solution
Answer:
21 is the lowest common denominator
B. 30% is the better deal
Explanation:
30% —> .3
.3x12=3.6
3.6>2.0
