11. The sum of these two angles is equal to 180.
So, 3x-4/2+4x+x/2+2=180.
Combine like terms: 4x-4/2+4x+2=180
Find and replace common denominator: 4x-4/2+8x+4/2=180
Combine like terms: 12x/2=180
Simplify: 6x=180, x=30
Check: 90-4/2=43, 120+15+2=137, 43+137=180

25 points for correct answer and giving brainliest
skad [1K]

Answer:

The height is 0 when it "drops".

3/2x + 9 = 0

3/2x = -9

3 = -9(2x)

3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

-3/2x + 9 = 0

-3/2x = -9

-3 = -9(2x)

-3 = -18x

6 = x

Find the relative minimum of<br> y = 3x^3 + 14x^2 - 11x - 46<br><br>(___, ___)​
Darina [25.2K]

Answer:

(0.353, -48)

Step-by-step explanation:

dy/dx = 9x² + 28x - 11 = 0

Using the quadratic formula:

x = -3.46 and 0.353

d²y/dx² = 18x + 28

Minima when d²y/dx² is positive

x = 0.35284 or (-14+sqrt(295))/9

y = 3x³ + 14x² - 11x - 46

y = -48.00651351
