The area of a triangle can be calculated as half the product of base length and height. We want the area to be no greater than 10 in².

a) (1/2)(4)(2x-3) ≤ 10

b) 4x -6 ≤ 10 . . . . . simplify

... 4x ≤ 16 . . . . . . . .add 6

... x ≤ 4 . . . . . . . . . divide by the coefficient of x

c) The maximum value of (2x -3) in is (2·4 -3) in = 5 in.

The triangle should be no more than 5 in high to have an area less than 10 in².

Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 7/sqrt 8x +10

Blizzard [7]

Assuming you meant

$y = \frac{7}{ \sqrt{8x+10} }$

Then you can compose the function g(x)

$g(x)= \sqrt{8x+10}$

With the function

$f(x)= \frac{7}{x}$

Because f (g(x) ) means that you first find (calculte) $\sqrt{8x+10}$ and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
