Answer:
An example of a quadratic equation is:
Step-by-step explanation:
This answer follows the standard form for a quadratic equation:
To solve this equation you do the following:
x^2 + 5x + 6 =0
The factors that can be added to get *5* and multiplied to get *6* are 3 & 2.
Therefore the new equation would be:
x^2 +3x + 2x + 6 = 0
<em>group the terms</em>: (x^2 +3x) (+2x + 6) = 0
<em>factorize</em><em>:</em><em> </em>x (x + 3) 2 (x + 3) = 0
<em>therefore</em><em>:</em><em> </em><em>(</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>)</em><em> </em><em>(</em><em>x</em><em> </em><em>+</em><em> </em><em>3</em><em>)</em><em> </em><em>=</em><em>0</em>
<em>x</em><em> </em><em>=</em><em> </em><em>-1</em><em> </em><em> </em><em>x</em><em> </em><em>=</em><em>-3</em>
Answer:
The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;
h = 42y
Step-by-step explanation:
Here, we want to write an equation;
From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards
Since it is a proportional relationship;
h = k * y
where k is the constant of proportionality given as 42
Hence;
h = 42 * y
h = 42y

Answer:
There is a probability of 0 that the student plays both string and brass.
Step-by-step explanation:
Looking at the universal set, there are 40 students at this high school, 15 of which play string, 20 play brass, and 5 play neither (probably drummers). Note how there is no intersection of A and B, which is the probability we are looking for.
Since there is no intersection in the universal set between subset A and subset B, you can say that there is a probability of 0 since there is no overlap between the two subsets.
Cheers.
2 is C. I don’t know what 3-4 is but I do know that 5 is D and 6 is A. And the answer to the bonus question is y= (x+2)² -14
Once more
2=C
3=?
4=?
5=D
6=A
BONUS= y= (x+2)² -14
Sorry I couldn’t help more.
