Answer:

x=

−1

14

Step-by-step explanation:

Let's solve your equation step-by-step.

7−2(3x+4)=8x

Step 1: Simplify both sides of the equation.

7−2(3x+4)=8x

7+(−2)(3x)+(−2)(4)=8x(Distribute)

7+−6x+−8=8x

(−6x)+(7+−8)=8x(Combine Like Terms)

−6x+−1=8x

−6x−1=8x

Step 2: Subtract 8x from both sides.

−6x−1−8x=8x−8x

−14x−1=0

Step 3: Add 1 to both sides.

−14x−1+1=0+1

−14x=1

Step 4: Divide both sides by -14.

−14x

−14

=

1

−14

x=

−1

Alejandro wants to adopt a puppy from an animal shelter. At the​ shelter, he finds eight puppies that he​ likes: a male and fema
alexgriva [62]

Answer:

Hence the required probability is, 3/4

Step-by-step explanation:  

At the shelter, he likes :  

a male coolie, a female coolie, a male boxer, a female boxer, a male beagle, a female beagle, a male Labrador, and a female Labrador.  

Let, A denote the event of selecting a male coolie and B denote the event of selecting a male Labrador.  

P(A) = 1/8 = P(B)  

Here the probability of selecting a puppy except A & B is,  

P(AUB)c = 1 - P(AUB) = 1 - { P(A) + P(B) } = 1 - 1/8 - 1/8 = 3/4

How many computers must the AB Computer Company sell to break even? Let x be the number of computers.
Eduardwww [97]

Answer:

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

R(x)=1.5x -----> equation A

C(x)=145+\frac{1}{4}x ----> equation B

where

C is the cost function

R is the revenue function

x is the number of computers sold

we know that

Break even is when the cost is equal to the revenue

so

equate equation A and equation B

1.5x=145+\frac{1}{4}x

Solve for x

subtract 1/4x both sides

1.5x-\frac{1}{4}x=145

1.5x-0.25x=145

1.25x=145

Divide by 1.25 both sides

x=116

therefore

The Company AB must sell 116 computers to break even
