{x{ x + 4<0 or 6x>-12)
lora16 [44]

Answer:

x\in (-\infty , -4) \cup (-2,+\infty)

Step-by-step explanation:

Solve the system of inequalities:

x + 4 < 0

OR:

6x > -12

The first inequality yields the solution:

x < -4

The second inequality gives the solution:

x > -2

The total solution is the disjunction of the individual solutions, i.e., the union of both.

It can be expressed as

\mathbf{x\in (-\infty , -4) \cup (-2,+\infty)}

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of t
alex41 [277]

Answer:

\angle MKJ  = 34

Step-by-step explanation:

Given

\angle LKJ = 124

Required

Find \angle MKJ

From the attachment:

The measure of \angle MKJ is calculated using the following expression:

\angle MKJ  + \angle LKM = \angle LKJ

Where

\angle LKM = 90 -- right-angled.

The expression becomes

\angle MKJ  + 90 = 124

\angle MKJ  = 124 - 90

\angle MKJ  = 34

The equation of a parabola is given.
BlackZzzverrR [31]

Answer:

Directrix equation:  y = 11/2

y = k - c = 6 - 1/2 = 11/2

Step-by-step explanation:

y=(1/2) x^2+6x+24

factor this

y =  (1/2)* [  x^2  + 12x  ]  +  24

y =  (1/2)* [  x^2  + 12x  + 36  -  36]  +  24

y =  (1/2)* [  (x + 6)^2  -  36]  +  24

y =  (1/2)*   (x + 6)^2  - 18 +  24

y =  (1/2)*   (x + 6)^2  + 6

y - 6 =  (1/2)*   (x + 6)^2

2*(y - 6)  =   (x + 6)^2

4c = 2,   (h, k) = (-6, 6)

c = 1/2

Directrix equation:  y = k - c = 6 - 1/2 = 11/2
