What's the question?
If it's "What's the difference?" or something like that, then the answer is 15. :)
Answer:
For me, the correct answer is B
Step-by-step explanation:
Hi, if I solve the following problem, which you'll see is very similar to yours, the correct answer is B.
That expression is equals to the following>
Finally we have this:
The problem that you claim does not match with any of the proposed answers, which is why I decided to solve the prior.
F(x)=-3(x)+4
Therefore this implies that we must put the -4 where we see an X on the equation
F(-4)=-3(-4)+4
=16
Answer:
(3) 2.5 cm
Step-by-step explanation:
We have been given that X is the circumcenter of triangle ABC.
Since we know that circumcenter of a triangle is the point where all the perpendicular bisectors of a triangle intersect.
We can see that MX is perpendicular to line AB, therefore, it will bisect line AB into two equal parts. Length of segment AM is 2.5 cm, therefore, length of MB will be also 2.5 cm.
We can also find length of MB using another property of circumcenter of triangle, which states that circumcenter of a triangle is equidistant from each vertex of the triangle.
In our right triangles AXM and BXM side length AX is equal to BX and XM is equal to itself and using Pythagoras theorem we will get two equation as:
Upon equating both equations we will get,
Upon subtracting from both sides of our equation we will get,
Now let us take the square root of both sides of our equation.
Upon substituting value of Am is our equation we will get,
Therefore, the length of MB is 2.5 centimeters and 3rd option is the correct choice.
