Well, yes and no.
Yes, because the straight line needs to pass through a number greater than 0, and 1 is obviously greater than 0.
However, y = x + 1 is not the same as y = x.
hope this helps.! let me know if it's in any way confusing..
I'd be happy to help!
Answer:
The pair (5, 3) means x or the pounds of cabbage is 5 and y or 3 is the dollars
So 5 pounds of cabbage costs $3
Cabbage is $0.60/pound
10,6 means 10 pounds of cabbage costs $6.
Step-by-step explanation:
Just divide the $3 by the 5 pounds of cabbage to get $.60 for each cabbage.

Step-by-step explanation:
hope it helps ^o^
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
No her estimate is to low because if you multiply 15.5 by 12 you get 186
