Answer:
<u>Given triangle:</u>
- ΔXYZ
- X(-1,2), Y(2,1), Z(-1, -2)
<u>D₀.₅(ΔXYZ) results in:</u>
- (x, y) → (0.5x, 0.5y)
- X'(-0.5, 1), Y'(1, 0.5), Z(-0.5, -1)
Answer:
y=-1/4x-4
Step-by-step explanation:
Which set of ordered pairs represent a function? O A {(1,0), (2,1), (2,3)} O B{(1,3), (1,4), (1,5)} O C{(1,5), (2,5), (3,5)} O D

Answer:
C
Step-by-step explanation:
C is the only answer that doesnt share x-values
Answer:
you are on the right track
Step-by-step explanation:
the second ones right so you are right :)
-x-y=-9
-3x-2y=-28
eliminate the x first
multiply the first system of equations by 3
(3)(-x)=-3x
(3)(-y)=-3y
(3)(-9)=-27
-3x-3y=-27
-3x-2y=-28
eliminate the systems of equations by subtracting
-3x--3x-3y--2y=-27--28
-3x+3x-3y+2y=-27+28
-y=1
multiply -1 for -y=-1 to get positive y
(-y)(-1)=(1)(-1)
y=-1
substitution method by using y=-1 into one of the system of equations
-x-y=-9
-x--1=-9
-x+1=-9
move +1 to the other side
sign changes from +1 to -1
-x+1-1=-9-1
-x=-10
multiply by -1 for -x=-10 to get positive x
(-x)(-1)=(-10)(-1)
x=10
answer:
x=10, y=-1
