Subtract 4x on both sides then divide by negative to all three numbers and your answer will be y = 1/2x - 3/2

HELP PLEASE!!!!!!!!

Luba_88 [7]

Answer:

AOB = 40 degrees

Step-by-step explanation:

The two smaller angles, AOB and BOC, add up to form AOC. That means that the angles of AOB and BOC sum up to the angle of AOC

$3x+4+8x-28=108\\11x=132\\x = 12\\\\3(12)+4=AOB\\AOB = 40 degrees$

Find the zeros of the following polynomial p(x) = 3x³ + 9x² - 12x

alexira [117]

Answer:

x = - 4, x = 0, x = 1

Step-by-step explanation:

To find the zeros equate p(x) to zero, that is

3x³ + 9x² - 12x = 0 ← divide through by 3

x³ + 3x² - 4x = 0 ← factor out x from each term

x(x² + 3x - 4) = 0

x(x + 4)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

x + 4 = 0 ⇒ x = - 4

x - 1 = 0 ⇒ x = 1

What sine function represents an amplitude of 1, a period of 2pi, a horizontal shift of our, and a vertical shift of -4

alexandr1967 [171]

ANSWER

$g(x) = \sin(x +4) - 4$

EXPLANATION

The basic sine function is

$f(x) = \sin(x)$

The transformed sine function has equation

$g(x) = a \sin(bx +c ) + d$

where a=1 is the amplitude

2π/b=2π is the period

c/b= 4 is the horizontal shift 4 units left.

d=-4 is a downward vertical shift of 4 units.

The required sine function is:

$g(x) = \sin(x +4) - 4$

What is the angle BCE ?<br>

spayn [35]

Answer:

∠ BCE = 80°

Step-by-step explanation:

∠ BCD = ∠ ABC = 35° ( alternate angles are congruent )

∠ DCE and ∠ CEF are same- side interior angles and supplementary, thus

∠ DCE + ∠ CEF = 180° , that is

∠ DCE + 135° = 180° ( subtract 135° from both sides )

∠ DCE = 45°

Thus

∠ BCE = ∠ BCD + ∠ DCE = 35° + 45° = 80°
