woman works out by running and swimming. When she runs, she burns 7 calories per minute. When she swims, she burns 8 calories pe
RSB [31]
An inequality to model this would be

7x + 8y ≥ 336.

We multiply the number of minutes running, x, by the number of calories burned each minute by running, 7.  We multiply the number of minutes swimming, y, by the number of calories burned each minute by swimming, 8.  Adding these together, it needs to be greater than or equal to 336, since she wants to burn at least that many calories.

Identify the restrictions on the domain of f(x) = quantity x minus 3 over quantity x plus 5. x ≠ 5 x ≠ −5 x ≠ 3 x ≠ −3
Fantom [35]

Answer:

x ≠ - 5

Step-by-step explanation:

Given

f(x) = \frac{x-3}{x+5}

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be.

solve : x + 5 = 0 ⇒ x = - 5 ← excluded value
