Answer:
(-1,1)
Step-by-step explanation:
All you have to do is plug it in the equation:
(x,y)
For (-1,1)
1=2(-1)+1
Simplify:
1=-1 but you know that 1≠-1 so (-1,1) is not it
For (3,7)
7=2(3)+1
Simplify:
7=7
For (-3,-5)
-5=2(-3)+1
-5=-5
Simplify:
For (0,1)
1=2(0)+1
1=1

ΔABC is similar to ΔDEF
Try to pair up all the similar sides.
AB = 15 cm
DE = ? cm
BC = 18 cm
EF = 6 cm
Now all you have to do is find out how the triangles are similar.
18/6 = 3
This means that triangle ABC is 3 times bigger than DEF.
15/3 = 5
So the answer is:
B. 5 cm
1.2(w + 4.7) = .84
Distribute the 1.2.
1.2*w= 1.2w
1.2*4.7= 5.64
1.2w+5.64=.84
Subtract 5.64 on both sides.
1.2w= -4.8
Divide 1.2 into both sides.
w= -4
I hope this helps!
