3. 17 < 25 . . . . 17 is on the left

4. 42 > 39 . . . . 39 is on the left

Step-by-step explanation:

3. If you do any counting at all, you know that starting from 1, you reach the number 17 before you reach the number 25. That is 17 is less than 25.

The numbers increase to the right on the number line, so the relationship is ...

17 < 25 . . . . . . . . 17 is to the left

4. You can count to 39 sooner than you can count to 42.

42 > 39 . . . . . . . . 39 is to the left

Additional comment

The point of the symbol (< or >) indicates the smaller value. The wider open end of the symbol indicates the larger value. One could say the symbol points to the number that is left on the number line.

Given a choice as to how to write an inequality, I often find it beneficial to write it so the "arrow" points to the left. That way, the written order of the operands corresponds to their relative locations on the number line.

For example, x < 3 means the number line will be shaded to the left of 3 to indicate possible values of x. 3 > x means the same thing, but requires more mental effort to figure out how to draw it on the number line.

"Back in the day" we played games that required counting. Jump rope or hide-and-seek, for example. It became obvious that it took 10 times as long to count to 100 as to count to 10. That is, the place values of the digits in a number were quite clear, as was their order.

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
