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.
\( \left|18\right|= \)
Calculate y given that \( x=2 \) and \( y=x \).
Find a y when x=2
\( y=\frac{2}{5}x+2 \)
Find a y when \( x=2 \)
\( y=5x \)
\( \left|3\right|= \)
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.
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 substitute 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!
Find a y when
10
\( 5x=1 \)
What is the value of x?
\( 5x=0 \)
\( \left|0.8\right|= \)
\( \left|-2\right|= \)
\( −\left|-18\right|= \)
What is the value of x?
Find a y when x=2
\( y=\frac{1}{2}x \)
Find a y when x=2
\( y=x-8 \)
\( 14x+3=17 \)
\( \left|x\right|= \)
\( -\lvert4^2\rvert= \)
