Answer: it is not a function
Step-by-step explanation:
Given :
= 3x + 1
The first thing is to make y the subject of the formula, that means we will take the square root of both sides
y = 
since y = , the the value of y could be positive or negative.
For example , 
= ± 2 , since -2 x -2 will also give + 4
For y = to be a function , there must be a unique value for y for each value of x , but this is not the case as y could be positive or negative for a single value of x , so it is not a function.
Answer:
6xy^-4
Step-by-step explanation:
we use the property
a^1×b^1=(ab)^1
Answer:
option D
Step-by-step explanation:
Given in the question are 4 number
5√1/3 - 
2 - 
9 + 
A Complex Number is a combination of a Real Number and an Imaginary Number
<h3>Example </h3>
a + ib
where a is real number
b is imaginary number
i is 'lota' which is √-1
<h3>So according to the definition above </h3>
is complex number in which
is real part
= 
is the imaginary part
Answer:
52 tickets cost $10 and 18 tickets cost $12
Step-by-step explanation:
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
52 tickets cost $10 and 18 tickets cost $12
The answer is 1/4 because 7/12 is larger than 1/2 but 1/4 is 2x smaller
