What's the point here? Why would you remove one of the ordered pairs?
The only thing I see here that hints at an answer is that -1 is the first term of both (-1,1) and -1,0). If we got rid of one of these, then the relationship could be a function; otherwise it is not a function. Why? Because in the case of a function, all first elements of the ordered pairs are unique (different from all the other first elements).
Answer: 11
Step by step: Diagnols in a rhombus bisect the angles meaning 2x=22, to solve this we do 22/2=11.
Hope this helps!
Answer:
a) The correct option is C: 4x
b) The correct option is B: 2x
Step-by-step explanation:
a) Usually when we have a real number multiplying a variable, we do not need to write the multiplication symbol.
So instead of writing:
4×x
We can write:
4x
And this will be equivalent.
Then in this case the correct option is C.
b) We know that if we have the multiplication of A by n, this will be equivalent to add A n times.
Then if we have the sum of A, for example, 4 times, we have:
A + A + A + A
And this can be written as 4*A
In this case, we have the expression x + x.
So we are adding x two times, then this can be written as: 2*x, or, as we said earlier, this also can be written as 2x.
Then the correct option is option B.
Ah...Trigonometry is fun!
The law of sines states:
The transitive property (switching the orders of the equations) applies here. Therfore, we can say that
We then plug in our given values to find C
Solving, we get 0.8557316387.
We're not done yet!We are trying to find an angle measure, so we'll do the inverse of the ratio we used (sin).
arcsin0.8557316387 (arcsin is the same as inverse sin)
=
58.8 (approximate)
So the measure of angle C is 58.8. You could check this by reinserting it into the equation

Answer: 45
Step-by-step explanation:
By factor method,
3 = 1, 3
9= 3, 3
15= 3, 5
LCM= 3*3*5
