Given that h(x) = 3x −19, find the value of x that makes h(x) = 71.

rosijanka [135]

Keywords:

<em>Equation, variable, value, clear </em>

For this case we have an equation with a variable of the form $y = h (x)$ . Where $h (x) = 3x-19$ . Given the value of $h (x) = 71$ , we want to find the value of the variable "x". So, we have:

$h (x) = 3x-19\\71 = 3x-19$

We must clear "x", for this, we add "19" to both sides of the equation:

$71 + 19 = 3x-19 + 19\\90 = 3x$

We divide between "3" on both sides of the equation:

$\frac {90} {3} = \frac {3x} {3}\\30 = x$

Thus, the value of the variable "x" is 30.

Answer:

$x = 30$

How do i solve this?

shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

$8^{2} + y^{2} = (8\sqrt{6} )^{2} \\ y^{2} = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y = \sqrt{320}$

∴ $y = 8\sqrt{5}$
