Chapter 8: Q36. (page 411)

Find the value of athat makes the ordered pair a solution of the equation.

y=-3x-1;a,5

Short Answer

Expert verified

The value a=-2 would make the ordered pair a,5 a solution of the given equation.

Step by step solution

01

Step 1. Given Information.

An equation: y=-3x-1 and the point: a,5

02

Step 2. Calculation.

To find the value of a, we will substitute coordinates of given point in our given equation and solve for a as:

y=鈭�3x鈭�1(Givenequation)5=鈭�3(a)鈭�1Substitutingx=aandy=55=鈭�3a鈭�15+1=鈭�3a鈭�1+1鈥勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌勨赌�础诲诲颈苍驳鈥�1鈥则辞鈥别补肠丑鈥剆颈诲别6=鈭�3a鈭�3a=6Switchingsides鈭�3a鈭�3=6鈭�3Dividingbothsidesby鈭�3a=鈭�2

Therefore, the value of a would be -2.

Step 3. Conclusion.

The value of a would be -2.

Write an inequality represented by the graph.

A skydiver uses an altimeter to track altitude so that he or she knows when to open the parachute. The altimeter determines altitude by measuring changes in atmospheric pressure. The graph below shows how pressure varies with altitude as a skydiver falls from 12,000 feet to ground level. (The elevation of the ground is assumed to be 0 feet with respect to sea level.)

  1. As a skydiver fall, does the atmospheric pressure increases or decreases?
  2. Describe the domain and range of the relation represented by the graph.
  3. Is the relation a function? Explain.
  4. Some altimeters can sound an alarm warning a skydiver to open the parachute when the altitude falls to a certain level. If the alarm is set to go off at an altitude of 3000 ft, approximately what atmospheric pressure will trigger the alarm?

To form the inverse of a relation represented by a set of ordered pairs, you switch the coordinates of each ordered pair. For example, the inverse of relation. 1,2,3,4,5,6is2,1,4,3,6,5. Give an example of a relation that is a function, but whose inverse is not a function.

The table shows the amount charged for standard ground shipping by an online electronics store.

  1. Is shipping cost a function of merchandise cost? Explain.
  2. Is merchandise cost a function of shipping cost? Explain.

The height of a person is measured every year from the age of 1 year to the age of 50 years.

  1. Do the ordered pairs age,height represent a function? Explain.
  2. Would you expect the ordered pairs height,age to represent a function? Why or why not?
