Chapter 8: Q5. (page 410)

Tell whether the ordered pair is a solution y=5x-7.

3. 2,3 4. 0,-6 5. 4,14 6. -3,-22

Short Answer

Expert verified

The ordered pair 4,14 is not a solution for the given equation.

Step by step solution

01

Step 1. Given Information

The given equation is y=5x-7.

02

Step 2. Calculation.

To check whether the ordered pair 4,14 is a solution forthe given equationor not, we will substitute coordinates of point 4,14 in our given equation as shown below:

y=5x−7Givenequation14=5(4)−7Substitutingx=4andy=1414=20−714≠13

03

Step 3. Conclusion.

Since both sides of equation are not equal, therefore, the ordered pair 4,14 is not a solution for the given equation.

Copy and complete using always, sometimes, or never: A relation is ? a function.

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?
