I want you to memorize one equation ... which I'm about to give you.
Using this equation, you can solve all speed, distance, and time problems.
ALL of them.

And I'll even give you a mnemonic ... an easy thing to remember that helps
you remember something that's harder to remember.

The name of the equation I'm about to give you is: The Dert Equation.
Here it is:
   D = R T ('D' 'Equals' 'R' 'T' . Get it ?)

It means " DISTANCE = (RATE) (TIME) ".

The Distance you cover
   is Equal to
   your Speed multiplied by the Time you travel.

If you drive at 50 miles per hour for 2 hours, how far do you go ?

D = R T D = (50 mi/hr) x (2 hr) = 100 miles

If you covered 150 miles in 3 hours, how fast were you driving ?

    D = R T 150 miles = (R) x (3 hours)

Divide each side by 1.5 hrs: 150 miles / 1.5 hrs = R = 50mi/hr

If the lake is 60 miles away, and Jim is driving at 40 miles per hour
the entire time, how long will it take her to get to the lake?

   D = R T    (60 mi) = (40mi/hr) x (Time)

Divide each side by 40 mi/hr: 60mi / (40 mi/hr) = Time = 1.5 hr

DERT gets you through all traveling situation, solves all problems,
and answers all questions. Except maybe why Jim is a girl.

It would take him 1 hour and 30 minutes because if he is driving 20 miles per half hour so it would be 1 hour and 30 mins

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
