Answer:
B. -5
C. 5
Step-by-step explanation:
The absolute value means make it positive.
When solving an equation with an absolute value it means we have two solutions, a positive and a negative
|x| =5
x = 5 and x = -5
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
Answer:
Scalene
Step-by-step explanation:
The three angles have different measures, so the sides have different lengths.
Sometimes it's hard not to assume something from a picture. Just because two of the sides look congruent doesn't mean they are. The information in the diagram (and geometry knowledge and logic!) are your guide.
Just use the formula 1/2bh
