Answer:

D. 20 ÷ 6 − 4

E. 1/6(20 − 24)

F. (20−24) ÷ 6

Step-by-step explanation:

6(x + 4) = 20

6(x) + 6(4) = 20

6x + 24 = 20

- 24 - 24

6x = -4

/6 /6

x = -4/6 or x = -2/3

D. 20 ÷ 6 − 4

20/6 - 4

20/6 - 24/6

-4/6 = -2/3

E. 1/6(20 − 24)

1/6(-4)

-4/6 = -2/3

F. (20 − 24) ÷ 6

- 4 / 6

-4/6 = -2/3

Hope this helps!

Answer:

Step-by-step explanation:

4x-6y=21

divide by 21

$\frac{4x}{21} -\frac{6y}{21} =1\\or~\frac{x}{\frac{21}{4} } +\frac{y}{-\frac{7}{2} } =1\\x~intercept =\frac{21}{4} =5.25 \\y~intercept=-\frac{7}{2} =-3.5$

if P(x)=1+6x-5x^2 represents the profit in selling x thousand Boombotix speakers, how many speakers should be sold to maximize p

Rashid [163]

Answer:

600

Step-by-step explanation:

$p(x) = 1 + 6x - 5x^2$

x max = $-b/2a$

a = -5

b = 6

-6/2(-5) = 6/10 = 3/5 = .6

.6 thousand = 600

600 speakers should be sold.

Alternatively, you can check the vertex of the parabola formed.
