Answer:
There are infinite solutions that solve the system 
Step-by-step explanation:
- The solution can be expressed as (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
- This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
- Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by , will solve the system. Then we have infinite solutions.

Answer:
h = 7.1 cm
Step-by-step explanation:
To find the height of the triangle, we can first find the area of the triangle using the Heron's formula:
Where a, b and c are the sides of the triangle and p is the semi perimeter of the triangle:
So the area of the triangle is:
Now, to find the height, we can use the following equation for the area of the triangle:
The height draw in the figure is relative to the side of 17 cm, so this side is the value of base used in the formula. So we have that:
Rounding to the nearest tenth, we have h = 7.1 cm
The median is the middle when numbers are in order from least to greatest.
So the number in the middle is 1.7
Answer:
Step-by-step explanation:
If we take the below diagram for the given triangles, then ∠B=∠E and ∠A=∠G if AB=GE or if BC=EF, then corresponding angles will be equal.
Therefore, if we rotate the diagram, then also the angles will remain the same.
