Given the domain (-4, 0,5), what is the range for the relation y = -2x +
mote1985 [20]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y =f(x) =   - 2x + 4

_________________________________

f( - 4) =  - 2( - 4) + 4

f( - 4) = 8 + 4

f( - 4) = 12

_________________________________

f(0) =  - 2(0) + 4

f(0) = 0 + 4

f(0) = 4

_________________________________

f(5) =  - 2(5) + 4

f(5) =  - 10 + 4

f(5) =  - 6

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .

Customers at an ice cream shop took a survey. The results showed that 144 customers rated the shop as being "very satisfactory."
stepladder [879]

Answer:

320 customers is the answer

Step-by-step explanation:

1. You have to divide 144 by 45% to find one percent of the customers (you get 3.2).

2. Once you get one percent of all of the customers (3.2) you multiply it by 100 to get 100 percent of the customers (or total number of customers).

So, 320 total customers

Have a great day, I hope you like the explination.
