Answer:

Maybe the first?

Step-by-step explanation:

If the first choice was 8 yards by 4 yards, then it would be correct.

A reduction means a scale factor of less than 1, while the second, third, and fourth choices have scale factors of 6, 12, and 2 respectively.

The correct answer is B.
A reduction would have the same ratio between the top and the side of the square, it would just be smaller. The original diagram is 20ft x 10ft, so the top is exactly twice the length of the side (a ratio of 2:1).

The ratio of answer A is not exactly 2:1, so it is not the correct answer.

Answer B is a 2:1 ratio and is SMALLER in size (convert inches into feet...10ftx5ft)

Answer C: it has a ratio of 2:1, but if you convert it from inches to feet you see that it is the SAME exact size as the original...20ftx10ft

Answer D: it is a ratio of 2:1, but it is 40ftx20ft, so it is LARGER than the original one.

Since answer B has the same ratio as the original, and it is the only one smaller in size, that is the correct answer.

Write the equation of a line in SLOPE INTERCEPT FORM with the following information.

kotykmax [81]

Answer:

y = 1/2x-1/2

Step-by-step explanation:

y = mx+b is the slope intercept form of a line

where m is the slope and b is the y intercept

y = 1/2x +b

We can substitute the point (3,1) in for x and y

1 = 1/2(3) +b

2/2 = 3/2 +b

2/2 -3/2 = b

-1/2 =b

y = 1/2x-1/2
