<h2>Examining the equation</h2>
We have 2 terms:
and 
For the sum of these to equal a negative number, in this case -3, one of these terms would have to be negative.
<h2>So what's the problem?</h2>
The function 
(square root of x) only returns positive values!
(See the attached image for a graph of )
Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as 
, we can't solve the solution, so we say that the equation <em>does not have any solutions.</em>
Answer:
A -9 is the y-intercept
Step-by-step explanation:
Answer: 2
Step-by-step explanation:
Answer:
tan A = 28/45
Step-by-step explanation:
opposite side
the tangent function is defined as tan A = ------------------------
adjacent side
Here the length of the side opposite angle A is 28 and that of the side adjacent to A is 45. Thus, the tangent of angle A is
tan A = 28/45
Answer:
y=8x/9
Step-by-step explanation:
Given that 8 euros were worth $9 and
24 euros were worth $27.
Let y represent the number of Euros and x no of dollars.
Given that the relation is of the form y = kx+C
When x=0 y =0,
i.e. C =0
Hence equation is of the form y = kx
Substitute x=8 and y =9
We get 9 = 8k
Or k =8/9
Hence relation is y=8x/9 is the relation between x and y.
WE can verify this for 27 dollars worth 24 euros.
24 =8/9(27) is true.
Thus equation is verified.
