Y-80x=65 in function notation

Answer:f(x) = 80x + 65f


Step-by-step explanation:

Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:

(625 - 465) / (7 - 5) = 160/2 = 80

Then, use m = 80 and one of the points to write the equation of your line in point-slope form:

y - y1 = m(x - x1)

y - 465 = 80(x - 5)

Convert that to standard form:

y = 80(x - 5) + 465

y = 80x - 400 + 465

y = 80x + 65

y - 80x = 65

In function notation, that's:

f(x) = 80x + 65

Answer:

f(x) = 80x + 65

Step-by-step explanation:

f(x) is another way of expressing y → y = f(x)

given y - 80x = 65 ( add 80x to both sides )

y = 80x + 65

or f(x) = 80x + 65 ← expressed in functional notation

In a pet store the number of birds is 10 less than twice the number of rabbits. if the pet store has 56 birds, how many rabbits
mr Goodwill [35]
B = 2r - 10
b = 56

56 = 2r - 10
56 + 10 = 2r
66 = 2r
66/2 = r
33 = r  <=== there are 33 rabbits

How do I solve this? It's so confusing.
Neporo4naja [7]
If I follow the angle degrees that they gave, your answers would be as follows:
I=145°
S=155° or 90°
E=78°
L=120° or 55°

Maybe this is right, sorry it took so long.
