Remark

Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.


Solution.

The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.


When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.


When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.

So the answer is C <<<<< Answer.


When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.

REWARDING 70 POINTS IN MATH TO THOSE WHO GET IT RIGHT<br> NO CHEATING ORELSE REPORTING
navik [9.2K]

Answer:

y = (2/3)x + 1.5

Step-by-step explanation:

To get our equation, we must first convert our values from inches to feet.

8/12 = 2/3 or 0.666667...

18/12 = 3/2 or 1.5

Now that we have our inches converted to feet, we can plug our values into the equation y = m(x) + b.

The length of a park is 250 meters. What is the length of the park in kilometers
Tatiana [17]
0.25 kilometers
Using the universal measurement
Kilo, hecto, deca, unit, deci, centi, milli
Kilometer, hectometer, decameter, meter, decimeter, centimeter, millimeter

From unit you would move three time to the left from your decimal point on your starting number 250. You would move it three times to the left because meter to kilometer is three decimals to the left

A way I remember my universal measurements is king (k-kilo), Henry (h-hecto), died (d-deca), unexpectedly (u-unit as in liters, meters, grams) drinking (d-deci), chocolate (c-centi) milk (m-milli)
