Solve and graph the solutions of the equation 2|x-2|-12=0
defon

2|x-2|-12=0

Rearrange variables to the left side of the question

2|x-2|=12

Dividing both sides of the equation by the coefficent of variables

|x-2|=12/2

Reduce the fraction

|x-2|=6

Split into two variables

x-2=6 or x-2=-6

Rearrange variables to the left side of the equation

x=6+2

x=8 or x=-4

when x=8

LHS=2|8-2|-12=0

RHS=0

LHS=RHS

x=8 is valid

A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.

A variable is a letter or symbol that stands in for any individual integer in a group of two or more. A constant is a letter or symbol that stands for a single particular number, whether it is known or unknown.

In mathematics, variables serve as stand-ins for unknowable numbers. Variables can be utilized in formulae, equations, and expressions in mathematics. When it's necessary to find the optimum solution, variables are frequently employed.

Suppose that y varies directly with x and y=12 when x=-2. what is when x=-6?
dlinn [17]
Y=4

How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.

A certain worker makes $12 per hour for the first 40 hours and $18 for every hour more than 40. Compute her pay for working 45 h
baherus [9]

Answer: $570

Step-by-step explanation:

She worked 5 hours more than 40.  Thus, for her extra hours she made 18*5, or $90.  For her other 40, she made 40*12, or $480.  Thus, she made 480+90 dollars, or $570.

At the coffee shop, two coffees and one latte cost $10.50. Three coffees and two lattes cost $17.00. What is the cost of one cof
maria [59]
Let the price of coffee be x and the price of latte be y.
Thus forming the equations given the information we shall have:
2x+y=10.50
y=10.50-2x.......i
3x+2y=17......ii
plugging i in ii we get:
3x+2(10.50-2x)=17
3x+21-4x=17
3x-4x=17-21
-x=-4
thus
x=4
Thus the cost of coffee is $4
thus the cost of latte will be:
y=10.50-2(4)
y=10.50-8
y=2.5
Price of latte is $2.5
