Answer:

2x² - 9x - 35

Step-by-step explanation:

f(x) × g(x) = (x - 7)(2x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 5) - 7(2x + 5) ← distribute both parenthesis

= 2x² + 5x - 14x - 35 ← collect like terms

= 2x² - 9x - 35

We can model this situation with a linear equation. We know for our problem that the initial point is (0, 25), and the next point is (10, 108.4). To relate those points and find the slope of our linear equation, we are going to use the formula: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }$ . Notice that we know from our points that: $x_{1}=0$ , $y_{1}=25$ , $x_{2}=10$ , and $y_{2}=108.4$ . So, lets replace those values in our formula to find $m$ :
$m= \frac{108.4-25}{10-0}$
$m= \frac{83.4}{10}$
$m=8.34$

Now that we have the slope of our linear equation, we can use the point slope formula: $y-y_{1}=m(x-x_{1})$ to complete our linear equation:
$y-25=8.34(x-0)$
$y-25=8.34x$
$y=8.34x+25$
Or in function notation: $f(x)=8.34x+25$

We can conclude that the equation that matches this situation is $y=8.34x+25$ .

Answer:

$\large\boxed{\dfrac{11}{4}x+8}$

Step-by-step explanation:

$\left(-\dfrac{11}{4}x+3\right)-2\left(-\dfrac{11}{4}x-\dfrac{5}{2}\right)\qquad\text{use the distributive property}\\\\=-\dfrac{11}{4}x+3+(-2)\left(-\dfrac{11}{4}x\right)+(-2)\left(-\dfrac{5}{2}\right)\\\\=-\dfrac{11}{4}x+3+\dfrac{22}{4}x+5\qquad\text{combine like terms}\\\\=\left(-\dfrac{11}{4}x+\dfrac{22}{4}x\right)+(3+5)\\\\=\dfrac{11}{4}x+8$
