What is the value of x in the equation 8 + 4 = 2 (x minus 1)?

satela [25.4K]

Answer:

x= 7

Step-by-step explanation:

The equation is 8+4= 2(x-1)

Distribute into the parenthesis.

8+4= 2x-2

Now, add.

12= 2x-2

Add 2 to both sides.

12= 2x-2

+2 +2

Then, divide by 2 to both sides to isolate the variable.

14= 2x

x=7

There exists a linear function f(x) such that f(6) = 8, f(2)=20, and f(a) = 16. What is the value of 2a?

atroni [7]

Answer:

a = 10/3.

Step-by-step explanation:

We write the linear function as follows:

f(x) = mx + b where m is the slope and b is the y-intercept.

f(6) = 6m + b = 8

f(2) = 2m + b = 20 Subtracting these 2 equations:

4m = -12

m = -3.

and -3 * 2 + b = 20 so:

b = 20 + 6 = 26.

So we have the linear function:

f(x) = -3 x + 26

f(a) = 16 = -3 a + 26

-3 a = 16-26

a = -10 * -3 = 10/3.

How to find cp if loss and sp are given

velikii [3]

Step-by-step explanation:

$\tt{ \: H \: E \: Y \: \: T \: H \: E \: R\: E \: }$ !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ $\large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}$

$\text{How \: did\: we \:get \:the \: formula : \: CP \: = Loss \: + \: SP} \:$ ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ $\text{CP - SP = Loss}$

Move SP to right hand side and change it's sign :

⟶ $\text{CP = Loss + SP}$

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡

Have a wonderful day / night ! ツ
