Answer:

Step-by-step explanation:
line equation in general y = mx + b
m is the slope, and
b is the y-intercept
3=-3m+b
-7=3m+b
if we plus this two equations
3-7=2b
2b=-4
b=-2
3m=b-3=-5
m=-5/3
So,

Answer:

Step-by-step explanation:
Consider similar triangles BMC and KMN.
In these triangles,

where O is the point of intersection of BC and MP.
Note that segment OP has the length the same as the side of the square ABCD. Hence,

Answer:
C and D if im wrong sorry
Step-by-step explanation:
Answer:
x=3z+5
/z^2
Step-by-step explanation:
Let's solve for x.
xz^2−3z−5=0
Step 1: Add 5 to both sides.
xz^2−3z−5+5=0+5
xz^2−3z=5
Step 2: Add 3z to both sides.
xz^2−3z+3z=5+3z
xz^2=3z+5
Step 3: Divide both sides by z^2.
xz^2
/z^2
=
3z+5/
z^2
x=
3z+5
/z^2
Answer:
x=3z+5
/z^2
(/ means over )
= -2
y= 2x+6. y= -2x-2
2x+6= -2x-2
+2x. +2x
____________
4x+6= -2
4x= -8
x=-2
