The output of a function is 10 more than 4 times the input.find the input when the output is -26

aleksandr82 [10.1K]

4x + 10 = -26

4x + 10 - 10 = -26 - 10

4x =-36

4x / 4 = -36 / 4

x = -9

The input is -9.

$\qquad$ ☀️ $\pink{\bf{ {Answer = \: \: -2 }}}$

Let assume –

$\bf (x_1,y_1) = (t,-6)$
$\bf (x_2,y_2) = (-1,3)$

As we know – The slope formula is or the change in the y values over the change in the x values.

$\qquad$ $\pink{\twoheadrightarrow\bf Slope, m = \dfrac{y_2-y_1}{x_2-x_1}}$

<u>According to the question </u>–

$\qquad$ $\pink{\twoheadrightarrow\bf \dfrac{y_2-y_1}{x_2-x_1} = 9}$

$\qquad$ $\twoheadrightarrow\sf \dfrac{3 -(-6)}{-1-t}=9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{3+6}{-1-t} = 9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{9}{-1-t}=9$

$\qquad$ $\twoheadrightarrow\sf \dfrac{1}{-1-t} = \dfrac{9}{9}$

$\qquad$ $\twoheadrightarrow\sf \dfrac{1}{-1-t} =\cancel{ \dfrac{9}{9}}$

$\qquad$ $\twoheadrightarrow\sf -1-t = 1$

$\qquad$ $\twoheadrightarrow\sf -t = 1+1$

$\qquad$ $\twoheadrightarrow\sf -t = 2$

$\qquad$ $\pink{\twoheadrightarrow\bf t = -2}$

Henceforth,Value of t will be -2.
