Find the slope determined by the following pair of points: (1/15,0) (2,1/4)

yawa3891 [41]

Answer:

$\large\boxed{m=\dfrac{15}{116}}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points:

$\left(\dfrac{1}{15},\ 0\right),\ \left(2,\ \dfrac{1}{4}\right)$

Substitute:

$m=\dfrac{\frac{1}{4}-0}{2-\frac{1}{15}}=\dfrac{\frac{1}{4}}{\frac{30}{15}-\frac{1}{15}}=\dfrac{\frac{1}{4}}{\frac{29}{15}}=\dfrac{1}{4}:\dfrac{29}{15}=\dfrac{1}{4}\cdot\dfrac{15}{29}=\dfrac{15}{116}$

Which expression is equivalent to x2+3x+ 3+ (2x+134+15) - (x+5))

tia_tia [17]

Answer:

$x^{2} + ( 4x) + (147)$

Step-by-step explanation:

Here, the given expression is

$x^{2} +3x +3 + (2x+134+15) - (x+5)$

Now, simplifying the brackets, we get

$x^{2} +3x +3 + (2x+134+15) - (x+5)$ = $x^{2} +3x +3 + 2x+134+15 - x -5$

Now, operate on the like terms.

= $x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)$

= $x^{2} + ( 4x) + (147)$

Hence, the given expression is simplified to the quadratic equation $x^{2} + ( 4x) + (147)$
