Answer:
The triangle is not acute because 2² + 4² < 5².
Step-by-step explanation:
It’s c I just took the test and got a hundred

From the second we can find:
y=7x-23
Now using this value of y in the first equation you have:
14x-2(7x-23)=46
14x-14x-46=46 which is always true meaning that there are infinitely many solutions.
Basically both equations describe the same line so every point on the line is a solution...
