6. Find JL.<br> Please and thank you. 5x-16=3x+4
IRINA_888 [86]

Answer:

JL = 68

Step-by-step explanation:

JM = ML

Hence, 3x + 4 = 5x - 16

Subtract 3x from both sides

4 = 2x - 16

Add 16 to both sides

20 = 2x

Divide both sides by 2

10 = x

Now we want to find JL

Note that JL = JM + ML

JM = 3x + 4 and x = 10

Substitute 10 for x

3(10) + 4

Multiply

30 + 4

Add

JM = 34

Because JM = ML

We simply multiply 34 times 2 to find the length of JL

34 * 2 = 68

JL = 68

The graph of the function f(x) = –(x + 6)(x + 2) is shown below.
schepotkina [342]

Answer:

a. The function is increasing for all real values of x where  x < –4.

Step-by-step explanation:

Let me help you, I have answered this question once in Brainly as well

Given the factored form of the function:

f(x) = -(x + 6)(x+2)

<=> f(x) = -x^{2} - 8x -12

We will convert to vertex form

f(x) = -(x+4)^{2} + 4

Let analyse other possible answers:

<u>a. The function is increasing for all real values of x where  x < –4.</u>

True, because  the parameter a = - 1 so the graph open down all over its domain

<u>b. The function is increasing for all real values of x where  –6 < x < –2.</u>

Wrong, the function decrease in the interval from –4.< x < -2

<u>c. The function is decreasing for all real values of x where  x < –6 and where x > –2.</u>

Wrong, the function increase in the interval from -6 < x < -4

<u>d. The function is decreasing for all real values of x where  x < –4.</u>

Wrong,  The function is increasing  for all real values of x where  x < –4.
