A) -4

Step-by-step explanation:

There are two ways of solving this:

1.) Plugging in the answer choices

Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign:  ≤)

You will then set the equation: -2x-6 ≤ 1

You will then take each answer choice and plug it into the original equation.

Plug in -4:  -2(-4)-6 ≤ 1   this will result in 2 ≤ 1

Plug in -3:   -2(-3)-6 ≤ 1 this will result in 0 ≤ 1

Plug in -2:   -2(-2)-6 ≤ 1 this will result in -2 ≤ 1

Plug in -1:     -2(-1)-6 ≤ 1 this will result in -4≤ 1

The only one that is not true is when you plug in x=-4 into the equation -2x-6.  This results in the equation being equal to 2.  2 is not less than 1, making the equation false.

Method 2: Solving the inequality

You can essentially solve for x like a normal inequality.

Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.

First: Add 6 to the right side

-2x ≤ 1+6 --->>>>  2x ≤ 7

Second:  Divid both sides by -2

***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***

x ≥ -3.5   (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)

x ≥ -3.5 states that any number greater or equal to -3.5 will work.  -4 is less than -3.5, thus it will not satisfy the inequality.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 2 answers

step-by-step explanation: the first one means to spread the product throughout the marketplace such that a large number of people can buy it.  

the second means the process of making a product or service available for the consumer or business user that needs it.
