Answer:
C or A
thats all i know hope it helps
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)
Answer:
x=2
Step-by-step explanation:
First, subtract four on both sides and then divide both sides by 2 to get x=2.
2x+4=8
<em>-4 -4</em>
2x=4
<em>÷ 2 ÷2 </em>
<u>x=2</u>
see the distance formula to find the length of the sides...
opposite sides equal it could be a rectangle or parallelogram
all sides equal, square or rhombus
adjacent equal, kite
and then the slope is used to check angles
if the product of the 2 lines in -1 the lines are perpendicular (right angle)
the the slopes of 2 lines are the same the sides are parallel.
