Subtract 3 from both sides so that the equation becomes -2x^2 + 5x - 13 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √((5)^2 - 4(-2)(-13)) ] / ( 2(-2) )
x = [-5 ± √(25 - (104) ) ] / ( -4 )
x = [-5 ± √(-79) ] / ( -4)
Since √-79 is nonreal, the answer to this question is that there are no real solutions.
Answer: m = 15w
Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.
Answer:
False
Step-by-step explanation:
an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Answer: A. (0, 1) and D. (2, ∞)
<u>Step-by-step explanation:</u>
When looking at the line <em>from left to right</em> we see the y-values as follows:
- y-values are increasing from -∞ to 0
- y-values are decreasing from 0 to 1
- y-values are increasing from 1 to 2
- y-values are decreasing from 2 to ∞
So, the y-values are decreasing on the interval from 0 to 1 (0, 1) and the interval from 2 to infinity (2, ∞).
