Answer:

B for the first graph (as x increases, y increases), D for the second graph (as x increases, y decreases), D for the third graph (minimum at y = -9), and A for the forth graph (the graph opens up because the a value in the equation is positive)

Answer:

as x increases, y increses

the parabola grows wider and taller, meaning that the y and x values will both increase:)

kolezko [41]

Step-by-step explanation:

<h2>=>first combine the like terms</h2>

5x-8x+12=24

-3x+12=24

<h2>=>substruct 12 from 12 and 24</h2>

-3x+12-12=24-12

-3x=12

<h2>=>divide -3 from both side</h2>

I don’t understand this

loris [4]

Answer:

62°

Step-by-step explanation:

The vertex angle is half the difference of the intercepted arc angles.

∠A = ½ (CE − BD)

x = ½ (4x − 10 − 26)

x = ½ (4x − 36)

x = 2x − 18

18 = x

Therefore, the measure of CE is:

4(18) − 10 = 62

Answer:

x = 16

Step-by-step explanation:

The angle bisector divides the sides proportionally.

(x -4)/9 = x/12

4(x -4) = 3x . . . . . . . multiply by 36

x = 16 . . . . . . . . . . . . add 16-3x to both sides, simplify

Find all solutions

Anton [14]

Answer:

The solutions of the equation are 0 , π

Step-by-step explanation:

* Lets revise some trigonometric identities

- sin² Ф + cos² Ф = 1

- tan² Ф + 1 = sec² Ф

* Lets solve the equation

∵ tan² x sec² x + 2 sec² x - tan² x = 2

- Replace sec² x by tan² x + 1 in the equation

∴ tan² x (tan² x + 1) + 2(tan² x + 1) - tan² x = 2

∴ tan^4 x + tan² x + 2 tan² x + 2 - tan² x = 2 ⇒ add the like terms

∴ tan^4 x + 2 tan² x + 2 = 2 ⇒ subtract 2 from both sides

∴ tan^4 x + 2 tan² x = 0

- Factorize the binomial by taking tan² x as a common factor

∴ tan² x (tan² x + 2) = 0

∴ tan² x = 0

OR

∴ tan² x + 2 = 0

∵ 0 ≤ x < 2π

∵ tan² x = 0 ⇒ take √ for both sides

∴ tan x = 0

∵ tan 0 = 0 , tan π = 0

∴ x = 0

∴ x = π

OR

∵ tan² x + 2 = 0 ⇒ subtract 2 from both sides

∴ tan² x = -2 ⇒ no square root for negative value

∴ tan² x = -2 is refused

∴ The solutions of the equation are 0 , π
