4x+2=19
Step 1. Subtracting 2 from both sides,
4x+2-2=19-2
4x=17
Step 2. Dividing 4 from both sides,
x=17/4
A quadrilateral MUST be a parallelogram if it has one pair of opposite sides both parallel and congruent. A quadrilateral MUST be a parallelogram if it has both pairs of its opposite angles congruent (or equal in measure). A quadrilateral MUST be a parallelogram if it has both diagonals bisecting each other.
Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

Solve for x

Find the value of y
substitute the value of x in the equation A

so

therefore
The solution is the point (-2,-2)
Traveling along the x-axis, we have

On the other hand, along the y-axis we get

Therefore the limit doesn't exist.
