Answer:

144

Step-by-step explanation:

angle A + angle B = 180 (supplementary angle)

A = 4B

4b+b=180

5b=180

Divide 5 on both sides to get b=36

180-36= measure of angle A

180-36=144

If f(x) = 2x - 1 and g(x) = x^2 - 2, find [g · f](x) please show me how to do this

larisa [96]

Answer:

(x² -7)/(2x + 1)

Step-by-step explanation:

f(x) = 2x+1 and g(x) = x² -7

thus: (g/f)(x) = g(x)/f(x) = x² -7/2x + 1

Write an equation in slope-intercept form of the line with slope −4/5 that contains the point (−5,−4).

Dmitry [639]

Answer:

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -4/5,

$y = - \frac{4}{5} x + c$

To find the y-intercept, substitute a pair of coordinates.

When x= -5, y= -4,

$- 4 = - \frac{4}{5} ( - 5) + c \\ - 4 = 4 + c \\ c = - 4 - 4 \\ c = - 8$

Thus, the equation of the line is

$y = - \frac{4}{5} x - 8$
