If f(x) = 3x-4, and g(x) = 2f(x)-1, what is g(5)?

kvasek [131]

Answer:

g(5) = 21

Step-by-step explanation:

Substituting f(x) into g(x):

g(x) = 2(3x-4) - 1

= 6x - 8 - 1

= 6x - 9

Seeing that g(x) = 6x-9,

g(5) = 6(5) - 9

= 30 - 9

= 21

In AWXY, m_W = (10x +17), m_X = (2x – 9)", and m_Y = (3x + 7)º.<br> Find mZY

ella [17]

Answer:

$m\angle Y=40^\circ$

Step-by-step explanation:

Suppose we have a triangle WXY whose internal angles are:

$m\angle W = 10x+17$

$m\angle X=2x-9$

$m\angle Y=3x+7$

The sum of the measures of the angles must be 180°, thus:

$10x+17 + 2x-9+3x+7=180$

Simplifying:

15x + 15 = 180

Subtracting 15:

15x = 165

Dividing by 15:

x = 11

Thus, the measure of angle Y is

$m\angle Y=3x+7=3*11+7=33+7=40$

$\mathbf{m\angle Y=40^\circ}$
