-3x+15=0
Add -15 both sides
-3x=-15
Divided by -3 both sides
x=-15/-3
x=5
Answer:
D.a relation only
Step-by-step explanation:
Relation: It is mapping between two non empty set A and B.
In relation any input value can have two or more than two output values.
Function: It is that relation in which every input value has only one output .
All function are relations but all relations are not function.
In given data
Image of 3 =4
Image of 3=3
By definition of function
It is not a function.
By definition of relation
It is a relation.
Hence, option D is true.
There are 12 inches in one foot:
1 ft = 12 in
We want to find how many feet are in 5000 inches:
x ft = 5000 in
Set up a proportion:
1/12 = x/5000
Cross multiply:
12x = 5000
Divide by 12:
x is about 416.67 feet.
Answer:
A
Step-by-step explanation:
For a function, the input only has one output. For example, if we take gender as our input and age as our output. There can be more than one female or male with different ages.
A function does not have to be a quantitative number, as long as it follows the one output for every input rule.
