How do you graph a possible situation?

1 answer:

4 0

To graph a situation that would involve a linear graph, first determine your x and y axes.
The x-axis will be the independent variable, one that does not change based on other variables. An example is time.

The y-axis, the dependent variable, depends on the independent variable.

The model equation for a linear line is y = mx + b.
"m" is the slope, and the "b" is the y-intercept (where the graph crosses the x-axis at x=0).

For example, a situtation could be that Joe starts with $10 in his account and adds $5 every day to his account.
The x-axis is time in days.
The y-axis is amount of money in his account.
The slope, or rate of change is 5.
The y-intercept, the amount of money he has at x=0 (0 days) is $10.

The equation would be y = 5x + 10
To draw this, plot the y-intercept at (0, 10), and the next point would be 5 units up and one unit to the right because the slope is 5, or 5/1 (remember slope is rise over run: "rise" up 5 and "over" to the right 1).

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6.

Yuki888 [10]

For this case we must simplify the following expression:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6}$

Simplifying the numerator, dividing all the terms by 4, we have:

$x ^ 2-8x + 12$

We factor by looking for two numbers that when added together give -8 and when multiplied by 12. These are: -6 and -2

$-6-2 = -8\\-6 * -2 = 12$

So, we have to:

$x ^ 2-8x + 12 = (x-6) (x-2)$

Simplifying the denominator:

We rewrite -17x as -18x + x:

$3x ^ 2-18x + x-6$

We factor the highest common denominator of each group:

$3x (x-6) +1 (x-6)$

We factor the polynomial by factoring the highest common denominator (x-6):

$(x-6) (3x + 1)$

So, we have to:

$3x ^ 2-17x-6 = (x-6) (3x + 1)$

Substituting in the original expression we have:

$\frac {(x-6) (x-2)} {(x-6) (3x + 1)} = \frac {x-2} {3x + 1}$

ANswer:

$\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6} = \frac {x-2} {3x + 1}$

Corresponding range of Celsius temperature C

julsineya [31]

By rearranging the equation, we find that 45 = 9/5 C +32 and 85 = 9/5 C +32
Therefore the answer is, 7.22 < C < 29.44

Number 7 what would all answers be

Over [174]

So... notice the picture below, that's P(x)

so $\bf \qquad \qquad \textit{vertex of a parabola}\\ \quad \\
y = {{ a}}x^2{{ +b}}x{{ +c}}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

so.. when the quantity is $\bf -\cfrac{{{ b}}}{2{{ a}}}$ , is when the profit $\bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}$ is the highest

after that, as you can see from the graph, it goes back down
