Answer:
negative square root will result in zero x-intercepts
Step-by-step explanation:
there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts
in this case, a=-1, b=4, c=-12
[-4±√4² - 4(-1)(-12)] / 2(-1)
= [-4 ± √16-48] / -2
= -4 ± √-32 / -2
Answer: 30
Step-by-step explanation:
*Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, ..., 30
* Multiples of 6: 6, 12, 18, 24, 30
* Multiples of 15: 15, 30
Answer: D. A number line with a closed circle on 6 and shading to the right
Step-by-step explanation:
Here, the given inequality,
2(x− 1) ≤ 10
2x - 2 ≤ 10
2x ≤ 10 + 2
2x ≤ 12
x ≤ 6 or 6 ≥ x
The value of x is all numbers less than 6 including 6.
⇒ A number line with a closed circle on 6 and shading to the left.
Thus, by the above explanation,
Only option D 'A number line with a closed circle on 6 and shading to the right' is not a way to represent the solution of the inequality.
