Is the triangle equilateral?
Answer:
Yes
Step-by-step explanation:
Longest side < sum of two other sides
Is a condition to form a triangle
12 < 7+9
12 < 16
So, yes
Answer:
1) Find the equation of the line that is parallel to the line y = 3x - 4 and
passes through the point (-4, 6).*
O y = 3X-8
y=3x + 18
y = (1/3) x + 18
Option 4
y = 3x-18
Y=-x^2-2
dy/dx=-2x and d2y/dx2=-2
Since acceleration is a negative constant, when the velocity equals zero, it will be an absolute maximum for y(x)
dy/dx=0 when -2x=0, x=0
y(0)=-2
So the vertex is at the absolute maximum, which is the point (0,-2)
Answer:
The lines don't intercept
Step-by-step explanation:
we have

isolate the variable y
Divide by 3 both sides

simplify
-----> equation A

Isolate the variable y

Divide by 6 both sides

simplify
-----> equation B
Compare equation A and equation B
The slopes are the same and the y-intercepts are different
Remember that
If two lines has the same slope, then the lines are parallel
therefore
In this problem line A and line B are parallel lines
The system of equations has no solution, because the lines don't intercept
