Value in mathematics indicates how much something is worth numerically.
Value in mathematics indicates how much something is worth numerically.
The word value signifies how much the function "is worth" – that is, what the value of will be in the function when we substitute any number in .
The values in the value table indicate how much of a function will be worth when we substitute with different values.
The distance of the number in absolute value from the digit .
It will always be positive because it is a distance.
\( \left|18\right|= \)
\( \left|-2\right|= \)
Calculate y given that \( x=2 \) and \( y=x \).
Find a y when x=2
\( y=\frac{2}{5}x+2 \)
\( 5x=0 \)
The "absolute value" can be viewed as the distance of a number from 0.
Therefore, the absolute value will not change the sign from negative to positive, it will always be positive.
When we have an exercise with these symbols || we understand that it refers to absolute value.
Absolute value does not relate to whether a number is positive or negative, but rather checks how far it is from zero.
In other words, 2 is 2 units away from zero, and -2 is also 2 units away from zero,
Therefore, absolute value essentially "zeroes out" the negativity of the number.
|-2| = 2
Calculate y given that and .
We are given the equation y=x
We are also given the value of x,
x=2
Therefore, we will insert the given value into the equation
y=2
And that's the solution!
Find a y when x=2
In this exercise, we are given the value of X, so we will substitute it into the formula.
It's important to remember that between an unknown and a number there is a multiplication sign, therefore:
y=2/5*(2)+2
y=4/5+2
Let's convert to a decimal fraction:
y=0.8+2
y=2.8
And that's the solution!
\( 5x=1 \)
What is the value of x?
\( \left|3\right|= \)
\( \left|0.8\right|= \)
Find a y when \( x=2 \)
\( y=5x \)
\( 14x+3=17 \)
\( x=\text{?} \)

Find a y when x=2
\( y=\frac{1}{2}x \)
\( \left|x\right|= \)
\( \left|3^2\right|= \)
\( \left|-19\frac{1}{4}\right|= \)
Find a y when x=2
\( y=x-8 \)
