Evaluate the expression when x=-5 and y=-7.

y-x+10

Short Answer

Expert verified

Thevalue of given expression would be8.

Step by step solution

01

Step 1. Given Information.

An expression: y-x+10

02

Step 2. Calculation.

To find the value of the given expression, we will substitute x=-5and y=-7 in our given expression as shown below:

y−x+10=−7−−5+10Substitutinggivenvalues=−7+5+10Usingproperty−−=+=8

03

Step 3. Conclusion.

The value of given expression would be 8.

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

4x-7y=19;-4,a

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?

Represent the relation as a graph and as a mapping diagram. Then tell whether the relation is a function. Explain your reasoning.

Suppose a relation is represented as a set of ordered pairs and as a mapping diagram. Which representation more clearly shows whether or not the relation is a function? Explain.
