Answer: $2x^{2} - 10x -28$

Step-by-step explanation:

We know that f(x) = 2x +4 and g(x) = x -7 so to find f(g(x)) multiply them.

(2x + 4)(x-7) Apply the distributive property twice

2x(x-7)

2x^2 - 14x

4(x-7) = 4x - 28

2x^2 - 14x + 4x -28

2x^2 -10x - 28

Find the length of the missing side. If necessary, round to the nearest tenth.

svetlana [45]

The pythagorean theorem states that the sum of the squares of two legs of a right triangle is equivalent to the hypotenuse.

So:

35^2 + b^2 = 40^2

1225 + b^2 = 1600

b^2 = 375

b = $\sqrt{375}$

b = 19.3649

<u>The missing side's length rounded to the nearest tenth is Option C, 19.4</u>

pav-90 [236]

Answer: $y=-3x-2$

Step-by-step explanation:

Using the values $x=-2, y=4$ and $x=1, y=-5$ , the slope is $\frac{-5-4}{1-(-2)}=-3$ .

So, the equation is:

$y-4=-3(x+2)\\\\y-4=-3x-6\\\\y=-3x-2$
