$3 {(4 + x)}^{2} - 10(x + 4) + 2 - 5$
so
$3( {x}^{2} + 8x + 16) - 10x - 40 + 3$
so
$3 {x}^{2} + 14x + 11$
take differential calculus
$6x + 14 = 0$
you will find x then y

Martin earned the following scores on his last five tests.

sdas [7]

Answer:

The mean of Martin's scores is 85.2

Step-by-step explanation:

In order to find the mean of a set of numbers, you will have to add up all of the numbers and divide the result by the total numbers in the set.

98 + 78 + 84 + 75 + 91 = 426

Since there are 5 numbers in total, we will do 426 divided by 5.

426 ÷ 5 = 85.2

So, the mean of Martin's scores is 85.2

Hi!

We can see here that this is a composition question.

And since the composition of g of f of x is x, we can conclude that g(x) is the inverse of f(x) (if you're confused, search up the definition of an inverse function).

To find an inverse function, we can take the f(x) function and change the positions of the x and y variables.

$f(x)=\frac{e^7^x+\sqrt{3}}{2}$
