Value in mathematics indicates how much something is worth numerically.

Question Types:

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 $Y$ will be in the function when we substitute any number in $X$.

The values in the value table indicate how much $Y$ of a function will be worth when we substitute $X$ with different values.

The distance of the number in absolute value from the digit $0$.

It will always be positive because it is a distance.

Question 1

Calculate y given that \( x=2 \) and \( y=x \).

Question 2

\( \left|18\right|= \)

Question 3

Find a y when x=2

\( y=\frac{2}{5}x+2 \)

Question 4

Find a y when \( x=2 \)

\( y=5x \)

Question 5

\( 5x=0 \)

Calculate y given that $x=2$ and $y=x$.

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!

$2$

$\left|18\right|=$

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.

$18$

Find a y when x=2

$y=\frac{2}{5}x+2$

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!

$2.8$

Find a y when $x=2$

$y=5x$

10

$5x=0$

$x=0$

Question 1

\( 5x=1 \)

What is the value of x?

Question 2

\( \left|0.8\right|= \)

Question 3

\( \left|-2\right|= \)

Question 4

\( \left|3\right|= \)

Question 5

Find a y when x=2

\( y=\frac{1}{2}x \)

$5x=1$

What is the value of x?

$x=\frac{1}{5}$

$\left|0.8\right|=$

$0.8$

$\left|-2\right|=$

$2$

$\left|3\right|=$

$3$

Find a y when x=2

$y=\frac{1}{2}x$

$1$

Question 1

Find a y when x=2

\( y=x-8 \)

Question 2

\( 14x+3=17 \)

\( x=\text{?} \)

Question 3

\( −\left|-18\right|= \)

Question 4

\( \left|-19\frac{1}{4}\right|= \)

Question 5

\( \left|3^2\right|= \)

Find a y when x=2

$y=x-8$

$-6$

$14x+3=17$

$x=\text{?}$

$x=1$

$−\left|-18\right|=$

$-18$

$\left|-19\frac{1}{4}\right|=$

$19\frac{1}{4}$

$\left|3^2\right|=$

$9$
