Answer: \(\textsf{Option D, (2x - 5)(x + 1)}\)
-------------------------------------------------------------------------------------------------------------
Given: \(\textsf{2x}^2\textsf{ - 3x - 5}\)
Find: \(\textsf{Factor the expression}\)
Solution: In order to factor the expression we will have two parenthesis with an x variable and a constant.
Determine important information
The standard form for a quadratic equation is \(ax^2 + bx + c\) and looking at our equation we can see that a = 2, b = -3, and c = -5.Now we need to determine two numbers that add up to b and multiply up to a * c. So, they must add up to -3 and multiply up to -10. The two numbers that fit the description is -5 and 2.Determine the factors
We plug in -5x and 2x instead of -3x and factor the expression by grouping.
\(2x^2-3x-5\)\(2x^2+2x-5x-5\)\(2x(x+1)-5(x+1)\)\((2x - 5)(x + 1)\)Therefore, the final answer that fits our solve solution would be option D, (2x - 5)(x + 1).
Answer:
\((2x -5)(x + 1)\)
Step-by-step explanation:
Hello!
Standard form of a quadratic: \(ax^2 + bx +c = 0\)
Given our equation: \(2x^2 - 3x - 5\)
a = 2b = -3c = -5We want to find two numbers that multiply to \(a*c\) but add up to \(b\).
ac = 2 * -5 = -10b = -3The two numbers that work for this is -5 and 2.
Now, expand -3x to -5x + 2x, and factor by grouping.
Factor by Grouping\(2x^2 - 3x - 5\)\(2x^2 +2x - 5x - 5\)\(2x(x + 1) - 5(x + 1)\)\((2x -5)(x + 1)\)The factored form is \((2x -5)(x + 1)\).

The Box-and-Whisker Graph shows the heights, in inches, of children between ages of 7 and 14. Between which two numbers would we find the lower 50% of the data?
A. Between 52 and 61 B. Between 61 and 64.5 C. Between 61 and 72 D. Between 57.5 and 61
Answers
Answer:
A. Between 52 and 61
Step-by-step explanation:
In this box and whisker plot Q1 represents the first quartile or the bottom 25% of all the data(25th percentile)
Q2 represents the second quartile and represents the lower 50% of all the data 50th percentile). The middle line represents the median of the data set.
Therefore the lower 50% of the data is found between 52 (lower limit) and 62(50th percentile)

Answer:
y = x/-4
Step-by-step explanation:
Looking at all the points, it's obvious that there is a change between signs in most of the points. -8 to 2, -4 to 1, and 4 to -1. This means that we're either multiplying or dividing by a negative number, as there's a change in signs. Since we're multiplying or dividing, we can forget about the 2 0s, as it doesn't change when multiplying it or dividing it by any number. Looking at the number change, x is always bigger than y. That means we're dividing since we're getting smaller from x to y. So, to find out what we're dividing we use x and divide it by y. For example, -8/2 = -4, -4/1 = -4, and 4/-1 = -4. That means we're dividing by -4. To write this as a linear function, we would do y = x and then whatever operation we're doing. In this case, it's y = x/-4 because we're dividing x by -4 to reach y :)
