A rental car company charges $68.80 per day to rent a car and $0.08
viktelen [127]

Answer:

  • 5 days maximum

Step-by-step explanation:

<u>Given</u>

  • Daily charge = $68.80
  • Charge per mile = $0.08
  • Target distance = 325 miles
  • Money limit = $370

<u>Required inequality:</u>

  • 68.8d + 325*0.08 ≤ 370

<u>Solving for d:</u>

  • 68.8d + 26 ≤ 370
  • 68.8d ≤ 344
  • d ≤ 344/68.8
  • d ≤ 5

Up to 5 days is the answer

-3x+8=y solve for if the equation is a function or non function
Ket [755]

Answer:

The equation is a function

Step-by-step explanation:

-3x + 8 = y

Reverse the function.

y = -3x + 8

Draw a graph of y vs x  (below)

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

36x+9 equals what<br> big blak vjndjgd
Yuki888 [10]

We can conclude that the equation 36x + 9 equals -1/4.

<h3>What exactly is an equation?</h3>
  • An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
  • 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.

So,

  • 36x + 9
  • 36x + 9 = 0
  • 36x = -9
  • x = -9/36
  • x = -1/4

Therefore, we can conclude that the equation 36x + 9 equals -1/4.
