Answer:
x∈ (-1, ∞)
Step-by-step explanation:
Solution of the inequality:
−2(3x − 1) < 8 ⇒ Divide both sides by -2, this will change inequalitysign to opposite
3x - 1 > -4 ⇒ add 1 to both sides3x > -3 ⇒ divide both sides by 3x > -1 ⇒ answerx∈ (-1, ∞) ⇒ answer as set8. A vending machine sells chips for $0.50 and

Peyton plans to deposit her next paycheck into her savings account.she makes $12.50 per hour and her next paycheck will be h hours of work the expression 12.50h + b represents the amount of money in her savings account after she deposits her next paycheck what does b represent in the expression
Answer: Current savings account balance
Step-by-step explanation:
since the equation is y = mx + b
mx would be the starting point so she earns 12.50 per hour so it's the current amount she has is 12.50.
Sorry if it dosen't make sense.
The b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.
What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one operation such as addition, subtraction, multiplication, or division.
We have,
The amount earned per hour = $12.50
The amount earned in her next paycheck = $12.50h
where h = number of hours
The expression that represents the amount of money in her savings account after depositing the next paycheck:
= 12.50h + b
We need to find what b represents in this expression.
b will represent the amount already in the saving account before depositing the next paycheck.
Thus the b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.

Solve the equation -5(x-2)=-(x+6)
Answer:
[tex] \huge{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}} [/tex]
Step-by-step explanation:
[tex] \sf{ - 5(x - 2) = - (x + 6)}[/tex]
Distribute -5 through the parentheses in left hand side
Similarly, distribute ( - ) sign through the parentheses in right hand side
[tex] \longrightarrow{ \sf{ - 5x + 10 = - x - 6}}[/tex]
Move x to left hand hand side and change it's sign
Similarly, move 10 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 5x + x = - 6 - 10}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{ - 4x = - 6 - 10}}[/tex]
The negative integers are always added but posses the negative ( - ) sign
[tex] \longrightarrow{ \sf{ - 4x = - 16}}[/tex]
Divide both sides by -4
[tex] \longrightarrow{ \sf{ \frac{ - 4x}{ - 4} = \frac{ - 16}{ - 4}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 4}}[/tex]
Hope I helped!
Best regards! :D
Steps to solve:
-5(x - 2) = -(x + 6)
~Simplify both sides
-5x + 10 = -x - 6
~Subtract 10 to both sides
-5x = -x - 16
~Add x to both sides
-4x = -16
~Divide -4 to both sides
x = 4

If a = b then a - c = b - c. This is the ________ property of equality.
Answer:
this property states that if quantity b, then b equals a. Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.
Hey there!
ANSWER: transitive
FILL IN THE BLANK:
If a = b then a - c = b - c. This is the transitive property of equality.

Here's a strange fact I recently found out:
"Scientists have long known that Africa is the cradle of human civilization. There, our ancestors shed most of their body hair around 2 million years ago, and their dark skin protected them from skin cancer and other harmful effects of UV radiation. When humans began leaving Africa 20,000 to 50,000 years ago, a skin-whitening mutation appeared randomly in a sole individual, according to a 2005 Penn State study. That mutation proved advantageous as humans moved into Europe. Why? Because it allowed the migrants increased access to vitamin D, which is crucial to absorbing calcium and keeping bones strong. "
