Answer:
not a right triangle
Step-by-step explanation:
you can use the pythagorean theorem to prove whether not this is a right triangle
if this triangle is a right triangle then the following equality should be true
a²+b²=c²
(9.75)²+(3.45)²=(10.24)²
(95.06)+(11.90)=(104.86)
106.96≠104.86
since the following equality is not true, this is not a right triangle.
Answer:
y=-3
Step-by-step explanation:
5(y+2/5)=-13
5y+10/5=-13
5y+2=-13
5y=-15
y=-3
Check:
5(-3+2/5)=-13
-15+2=-13
-13=-13
The table shows a linear function :)
