Mathematics
1 answer:
Serjik [45]3 years ago
6 0

Answer:

the domain is that x is a set of real numbers.

the range is y ≤ -3

Step-by-step explanation:

y = -|x + 3|

y is either positive or equal to zero.

Now, x is all real numbers because any value of x used will yield a valid value of y.

Thus, we can say that the domain is that x is a set of real numbers.

Now, for the range:

The minus sign in front of the absolute value indicates that the function has a maximum value.

Thus, the range is y ≤ -3

Dillard's checking account charges a $13.25 monthly service fee and a $0.24 per check fee. if Dillard writes 18 check per month,
Arturiano [62]

Answer:

C. Yes, because his monthly fees are currently greater than $17.50.

Step-by-step explanation:

To find out if Dillard will benefit from changing to a checking account that charges $17.50 with no per check fee, we first need to calculate how much he currently spends.

Since Dillard write 18 checks per month, we need to multiply that by $0.24 and add the total value to his current monthly service fee.

18 x 0.24 = $4.5

Now that we know how much he spends for all the 18 check a month we just add his monthly service fee to get his total amount.

$4.5 + $13.25 = $17.75

The other checking account charges $17.50 per month without a service fee, therefore:

$17.75 > $17.50

So Dillard with benefit from changing his checking account.
