Solve the equation -5(x-2)=-(x+6)

Answers

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

Answers

Answer:

Step-by-step explanation:

Let's solve for c.

y=mx+c

Step 1: Flip the equation.

mx+c=y

Step 2: Add -mx to both sides.

mx+c+−mx=y+−mx

c=−mx+y

If a = b then a - c = b - c. This is the ________ property of equality.

Answers

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. "

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

Answers

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.

So g(x) just means the function of the x term as the original value of this is 2x+1 then this is your starting point, when it says -2g(x) all you have to do is do the same to the other side of the equation so just do (2x+1) x -2 this would be -4x-2 as the signs would change due to the negative 2 as a positive and a negative make a negative so the answer is the second one -2g(x) = -4x-2
