Answer:
vertical stretch
Step-by-step explanation:
Ordered pairs that work for this direct variation are (4, 3), (8, 6) and (12, 9).
In order to find these, we must first find the value of the direct variation coefficient. We can do that using the base equation y = kx and then by plugging in to find k.
y = kx
12 = k(16)
3/4 = k
Now that we have k, we can model the equation as y = 3/4x. We can also find any number of ordered pairs by using the x value and finding the y value. All of the above answers work.
Charmaine= x
William=x+3
3 times Charmaine = 3x
2times William = 2x+6
5x+6=76
5x=76-6
5x=70
X=14
Charmaine is 14
William is 3 years older so is 17
Check:
17x2= 34
14x3=42
34+42=76
So Charmaine is 14
William is 17
174/29 = 6 times the difference
17*6 = 102
12*6= 72
34*6 =204
15*6 = 90
so the answer is A
45 million *
= 45million * 16 = 720million
Or you can use
A is equal to 45 million
To find the rate, k, we can plug in:
Knowing that t = 4
