I would first convert the mixed fraction into an improper fraction. To put it lightly, the reciprocal is the numerator and denominator are switched. For this instance it would be 4/37.

[ f(x) = 3x + 2<br> g(x) = x2<br> Find gf(5)<br> Find fg(x)

marusya05 [52]

Answer:

gf(5) = 289.

fg(x) = 3x^2 + 2.

Step-by-step explanation:

f(5) = 3(5) + 2 = 17

So gf(5) = 17^2 = 289.

fg(x) = 3(x^2) + 2 (we replace the x in f(x) by g(x)).

= 3x^2 + 2.

Please fill in the final row (x)

Nata [24]

Answer:

x = 11

Step-by-step explanation:

The Frequency column has to total 50 ( number of rolls on dice )

Thus total the given frequencies and equate to 50, that is

12 + 8 + 7 + 3 + 9 + x = 50

39 + x = 50 ( subtract 39 from both sides )

x = 11

The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear and the line has a slope of ____.

Anton [14]

Answer: -1

Step-by-step explanation:

Given: The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear

The slope of a line passing through points (a,b) and (c,d) is given by :-

$m=\frac{d-b}{c-a}$

Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-

$m=\frac{6-4}{2-4}=\frac{2}{-2}=-1$

Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
