 <span>y" + 9y = 0 
m^2 + 9 = 0 
m = ± 3i 

yH = C1 cos 3t + C2 sin 3t 

yP = C3 t sin 3t + C4 t cos 3t
hope this helps </span>

Find the slope of the line graphed below
Korolek [52]

Answer:

Slope = 1

Step-by-step explanation:

(x1, y1) = (-5, -3)

(x2, y2) = (-1, 1)

(y2 - y1) / (x2 - x1) = (1 - -3) / (-1 - -5) = 4 / 4 = 1

Slope = 1

F(x) = x² + 5x-1 is shifted 3 units right. The result is g(x). What is g(x)?
CaHeK987 [17]

Answer:

D

Step-by-step explanation:

When a function is being shifted to the left, all x values will be added by y units shifted. (The constant that comes with x is excluded, eg. 3x shifted by 2 units left, becomes 3(x+2) and not 3x+2.)

Likewise, when a function is being shifted to the right, all x values will be subtracted by y units shifted. (Constant rules applies as well.)

Given f(x) is shifted 3 units right,

the new function, g(x) becomes:

g(x) = {(x - 3)}^{2}  + 5(x - 3) - 1

Therefore the answer is D in this case.

Solve similar triangles (advanced)
andrew11 [14]

Answer:

Step-by-step explanation:

There are 2 similar triangles.

EDA and CBA

From that we can get the following proportion.

ED / CB = AD / AB

Filling in the letters we get

6/x = (4 + 3)/3            Combine

6/x = 7/3                    Cross Multiply

7x =6*3

7x = 18                        Divide by 7

x = 2.57
