nika2105 [10]

4. A yellow cab Taxi charges $5.00 flat rate in addition of $0.65 per mile. Jan has no more than $20 to spend on a ride.
gogolik [260]

Answer:

5+0.65x\le 20

Step-by-step explanation:

Let x be the number of miles Jan can drive in a taxi.

The cost of this ride consists of

  • $5.00 flat rate
  • $.065 per mile

So, per x miles Jan will pay $0.65x and the total cost of the ride will be

$5.00+$0.65x

Jan has no more than $20 to spend on a ride, then the total cost of his ride must be less or equal to $20. Mathematically, you can write this as

5+0.65x\le 20

If f(x) =2x-6 then f(1)=​
marin [14]

Answer:

f(1) = -4

Step-by-step explanation:

Given that,

f(x) = 2x-6

We need to find the value of f(1).

Put x = 1 in the above expression.

f(1) = 2(1)-6

= 2-6

= -4

So, the value of f(1) is equal to -4.
