A domain x ∈ {2, 4 }

To find the domain, that is the values of x that produce the values in the range , solve for x , that is

x + 5 = 7 ⇒ x = 7 - 5 = 2

x + 5 = 9 ⇒ x = 9 - 5 = 4

What is the equation?
Minchanka [31]

Answer:

y - 4 = (1/3)(x - 9)  or x - 3y = -3

Step-by-step explanation:

Here we're told that the slope is 1/3 and that (9, 4) is a point on the line.  Use the point-slope formula  y - k = m(x - h).  Substitute 4 for k, 9 for h and 1/3 for m:

y - 4 = (1/3)(x - 9)  (point-slope formula)

3y - 12 = x - 9  (standard form of the same equation) = >

     -12 + 9 = x - 3y, or x - 3y = -3 (standard form)

The sum of two numbers is 45 and there difference is 5 what are the two numbers?
Kamila [148]
Let the two numbers be x and y.
The sum is 45, therefore
x + y = 45                    (1)

The difference is 5, therefore
x - y = 5                      (2)

Add equations (1) and (2).
x + y + (x - y) = 45 + 5
2x = 50
x = 25

From (1), obtain
25 + y = 45
y = 45 - 25 = 20


Answer:  20 and 25
