Answer:
9
Step-by-step explanation:
x didn't change in value, y changed by 9
the distance between the two points is 9
It is 4x4 then divide that by 2 since a triangle is half of a square so 16 divided by 2 which is 8
Use Pythagorean theory
C^2 = a^+ b^2
In this case you have c and a
B^2= c^2-a^2
B^2 = 12^2-5^2
B^2= 144-25
B^2 = 119
Square root both sides
X= 10.90871
Answer:
The right answer is the second
Step-by-step explanation:
D=b^2-4ac
D=25+12
D=37
Answer:
x=8
Step-by-step explanation:
9x - 8 = 64 (being vertically opposite angles)
9x = 64 + 8
x=72/9
x=8
9x -8
9*8 -8
72-8
64
