Answer:

Step-by-step explanation:

I just answered this for someone else... here is the same answer I gave them

QR + RS +SQ = perimeter

2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative SQ=QS)

2*5 + 2 * 7 + 20 = perimeter

10 + 14 + 20 = p

44 = p

Answer:

C. 18:30

Step-by-step explanation:

Divide the y values (games played) by the x values (games won) to find your ratio. The ratio across each of these pairs is 1.666667...

Using the ratio provided, 18:30, divide 30 by 18.

30/18 = 1.666667...

It's a match!

Therefore, the answer is C. 18:30

1. Change x = 4t into x = 3t

$4t\cdot\frac{3}{4}=3t$ so

$y=(\frac{3}{4}t)^2-1=\frac{9}{16}t^2-1$

Answer A and D are wrong.

2. Change x = 4t into x = 2t

$4t\cdot\frac{1}{2}=2t$ and

$y=(\frac{1}{2}t)^2-1=\frac{t^2}{4}-1$

Answer b is correct.

3. Change x = 4t into x = 8t

$4t\cdot2=8t$ and

$y=(2t)^2-1=4t^2-1$

Answer C. is correct, E. is wrong.
