Answer:
(3/2, 6)
Step-by-step explanation:
y = 4x
8x + y = 18
this says y is 4x so you can replace y with 4x
8x + 4x = 18
12x = 18
/12 /12
x = 3/2
now sub x into y = 4(3/2)
y = 12/2
y = 6
total cost = membership +cost per class* number of classes
y = 275+5*x
Choice C
Answer:
D.
Thats what gauth.math said
The domain is the input (x) value. Since the equation is not provided with any input limit the answer is negative infinity to infinity.
The answer is the last choice.
The population of the Bulbul birds at the start of the migration season is 1800.
<h3>
Exponential function</h3>
An exponential function is given by:
y = abˣ
Let y, x are variables, a is the initial value and b is the multiplication factor.
Let P be the population of the bird t days since the start of the migration season.
