Step-by-step explanation:

f(x) = 5x - 8

g(x) = 9 - 6x²

= (fog)(-3)

= f( g(3) )

= 5x - 8

= 5(9 - 6x²) - 8

= 5(9 - 6(-3)² ) - 8

= 5(9 - 54) - 8

= 5(-45) - 8

= -225 - 8

= -233

(fog)(-3) = -233

If one of the roots of the quadratice quation x2+kx-12=0is4,what is the value of k?

uysha [10]

<h3>Given Equation:</h3>

$\huge \purple {\rm { {x}^{2} + kx - 12 = 0}}$

<h3>Value:</h3>

$\huge \purple {\rm {x = 4}}$

$\huge \purple {\rm {The \: value \: of \: k.}}$

<h3>Solution:</h3>

$\huge \purple {\rm { {(4)}^{2} + k(4) - 12 = 0}}$

$\huge \purple {\rm {or, \: 16 + 4 k - 12 = 0}}$

$\huge \purple {\rm {or, \: 4k = - 4}}$

$\huge \purple {\rm {or, \: k = \frac{ - 4}{4} = - 1}}$

<h2>Answer:</h2>

$\huge \purple {\sf {The \: value \: of \: k \: is \: -1}}$
