I believe it would be 1/12 because if you put it as a fraction and multiply across.
you have to look at the color word not the color
The angles are 45° 60° and 75°
Elaboration:
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
I can’t really see sorry could you take a better picture?
Answers:
The first and third options should be selected.
- The ordered pair (10,5) is a solution to the first equation because it makes the first equation true.
- The ordered pair (10,5) is not a solution to the system because it makes at least one of the equations false.
Explanation:
In order for a point to be a solution to a system of equations, it must make both equations true when its x and y values are substituted in. That being said, we need to test if (10,5) is a solution for the two equations.
Let's try the first equation. Substitute 10 for x and 5 for y and solve:
-5 does equal -5, so (10,5) is a solution to the first equation.
Next, let's test the second equation. Do the same:
However, 20 does not equal 11, therefore (10,5) is not a solution to the second equation.
So far, we know that (10,5) is a solution to the first equation, but not the second equation. Knowing this, it cannot be a solution to the system because it does not make both equations true. Therefore, only the first and third options should be selected.
We have that
<span>f(x) =2/x
</span>and
<span>g(x)=1/(-3-x)
we know that
</span>the solutions to f(x) = g(x) is the intersection of both graphs
the <span>intersection of both graphs is the point (-2,-1)
</span>
the answer is the option
<span>
A) (-2, -1)
