Answer:
<h2>Q = -6</h2>
Step-by-step explanation:
If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.
x - 3y = 4 <em>multiply both sides by 2</em>
2x - 6y = 8
Therefore Q = -6
The answer should be 6(8)-4
F(x) is 44
Answer:
Option D. It's a perfect square trinomial.
Step-by-step explanation:
(a) 36x² - 4x + 16
= (6x)² - 2(2x) + (4)²
It's not a perfect square trinomial
(b) 16x² - 8x + 36
= (4x)² - 2x(4x) + (6)²
It's not a perfect square trinomial
(c) 25x² + 9x + 4
= (5x)² + 2
+ (2)²
It's not a perfect square trinomial
(d) 4x² + 20x + 25
= (2x)² + 2(10x) + (5)²
= (2x+5)²
It's a perfect square trinomial.
Answer: X=6 or X= -6
Step-by-step explanation:
To find what x equals, square root both sides. The square root of 36 is positive or negative 6
It has to be solved first.
Step-by-step explanation:
- Parentheses has to be solved first according to the BODMAS Principle which is Brackets Open Division Multiplication Addition and Subtraction
- If this is not followed, the answers will be different and will not get the right answer.
- It is the same as PEDMAS which is Parenthesis Exponents Division Multiplication Addition and Subtraction
