Answer:
Going from 1 to 7. The not functions are 2,4,6, and 7
Step-by-step explanation:
How you can determine if its a function is if all x values are different. Vertical line test.
Answer:
17x² - 5x + 11 = 0
Step-by-step explanation:
To add or subtract a polynomial do the operation with like - terms.
i.e., Two terms of x² gets added or subtracted. Similarly terms of x and constant.
Here, we have to subtract:
Club all the like terms for easier simplification. We get:
Multiplying by -1 throughout:
17x² - 5x + 11 = 0 is the answer.
Answer:
£ 35
Step-by-step explanation:
Ratio = 6 : 1
Gordon's share = 6x
Malachy's share = x
6x - x = 25
5x = 25
x = 25/5
x = 5
Gordon's share = 6x = 6*5 = 30
Malachy's share = x = 5
Total money they get = 30 + 5 = £35
By definition and properties of the <em>absolute</em> value used on the <em>quadratic</em> equation we conclude that F(|- 4|) = 12.
<h3>How to evaluate a quadratic equation with an absolute value</h3>
Herein we must apply the definition of <em>absolute</em> value prior to evaluating the quadratic equation defined in the statement. From algebra we know that absolute values are defined as:
|x| = x, when x ≥ 0 or - x, when x < 0. (1)
Then, we apply (1) on the quadratic equation:
F(|x|) = |x|² - 2 · |x| + 4
As x < 0, by <em>absolute value</em> properties:
F(|x|) = x² + 2 · x + 4
F(|- 4|) = (- 4)² + 2 · (- 4) + 4
F(|- 4|) = 16 - 8 + 4
F(|- 4|) = 12
By definition and properties of the <em>absolute</em> value used on the <em>quadratic</em> equation we conclude that F(|- 4|) = 12.
