3x+7= -2
+2. +2
0=3x+9
The slope is 3.
The slope formula is "y=mx+b" m equals the slope.

I dont know the answer!! I give brainlist...

iragen [17]

Answer:

A. (f + g)(1) = - 9

B. (f - g)(0) = -7

C. (fg)(3) = 0

Step-by-step explanation:

A. (f + g)(1) = f(1) + g(1) f(1) = 1^2 - 9 = 1 - 9 = - 8 g(1) = 1 - 2 = - 1

= -8 -1 = -9

B. (f - g)(0) = f(0) - g(0) f(0) = 0^2 - 9 = 0 - 9 = -9 g(0) = 0 - 2 = -2

= -9 + 2 = -7

C. (fg)(3) = f(3)(g(3) f(3) = 3^2 - 9 = 9 - 9 = 0 g(3) = 3 - 2 = 1

= 0(1) = 0

I don’t understand how to find the height

ANTONII [103]

Answer:

height, x is 235 ft

Step-by-step explanation:

From trigonometric ratios:

$\cos( \theta) = \frac{adjacent}{hypotenuse}$

but:

$\theta = 90 \degree - 36 \degree \\ \theta = 54 \degree$

adjacent is x

hypotenuse is 400 ft

$\ \cos ( 54 \degree) = \frac{x}{400} \\ \\ x = 400 \ \cos (54 \degree) \\ x = 235 \: \: feet$
