Answer:
c
Step-by-step explanation:
The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:
Putting x = 3y+1 in equation 2 from equation 1
Subtracting 1 from both sides
Dividing both sides by 7
Putting y=2 in equation 1
Hence,
The solution is: x= 7 and y = 2

Answer:
Option B. 1/2
Step-by-step explanation:
The smaller triangle is a dilation of the larger triangle with the center of dilation at (2, -1).
we have to calculate the scale factor of the dilation.
One point of the large triangle is (-4, -1). After dilation it has become (-1, -1) of the smaller one.
If we consider the x coordinates of the point x = -4 has reduced down to -1 therefore scale factor = side of small triangle/side of the large triangle = (2 + 1)/(2 + 4) = 3/6 = 1/2
Therefore Option B. 1/2 is the answer.
