Answer:
Domain: All Real Numbers
Range: All Real Numbers
Step-by-step explanation:
F is
F = {(x, y ) | x + y = 10}
(x,y) is the ordered pair
x + y = 10 is the expression
We can rearrange it
y = 10 - x
And then we can plot it using a graphing calculator. See attached image
By looking at the plot and examining the expression, we can see that there are no restrictions over x or y.
This means that the domain and range are all real numbers
Domain: All Real Numbers
Range: All Real Numbers
F is a function because it is a relation that associates each element x to a single element y.
Answer:
y = (5/6)x - 7
is with
y = - (6/5)x + 1
y = - (5/6)x - 8
is with
y = (6/5)x - 5
y = - (7/4)x - 1
is with
y = (4/7)x + 9
y = (7/4)x - 2
is with
y = - (4/7)x + 2
Step-by-step explanation:
You can double check by dividing -1 by the number before x. The answer from that calculation will be the number before the x of the perpendicular line's equation
Answer:
30 = 2 x 3 x 5
Step-by-step explanation:
The secret number is the least whole number that has three different prime factors. Since, this is the least whole number it should have the 3 smallest prime numbers as its factors.
The 3 smallest prime numbers are: 2, 3 and 5
The number that will have 2, 3 and 5 as its only factors will be the least whole number with 3 different prime factors.
So, the secret number must be = 2 x 3 x 5 = 30
If you are to make it to proper fraction it would be 7 1/8 if have to make it to a just decimal it would be 7.125
