- subtract the 12 from both sides so that it becomes the last constant term in the quadratic equation which should now equal 0.
- take the 4x
- half the coefficient of 4 (2)
- square it (4)
- add it to the equation (+4)
- subtract it from the equation (-4)
- factorise the square (x+2)^2 expands to (x^2 + 4x + 2) as {a+b}^2={a^2 + ab + ba + b^2}
- now the equation is in turning point form.
- to find x, add 16 and square root 16 and (x+2)
- subtract 2 from positive or negative 4 (as -4^2 and 4^2 both equal 16).
- This should give you two values for x, -6 and 2.
I really hope that this helped :)
Answer: Hexagon
Explanation: Just trust me ;)
Answer:
The answer is
A) Skewed left
Step-by-step explanation:
The line plot has about 3 point that are going more to the left than the others therefore it is skewed left.
Given:
The graph given passes through two points (0, 2) and (-4, 8).
General Idea:
We can find the slope (m) of a line passing through two points say A and B using the below formula.
Applying the concept:
Slope of the line given using the two points (0, 2) and (-4, 8).
Out of the five options given , we need to check which options have slope as -6/4 or -3/2 by rewriting (if needed) the given to slope intercept form y =mx + b and compare the same.
Conclusion:
Rewriting the first option, the slope is -6/4 as shown below.
Rewriting the fourth option, the slope is -3/2 as show below.
Rewriting the fifth option, the slope is -3/2 as shown below.
Divide by 2 throughout the equation
Multiply by what? I do not understand the question?¿
