Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40
You have to create your own word problem based off what Uu guys learned in class
The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet
The one in Arizona would be lower than it, so the elevation will definitely be -9 feet
