Answer:
Step-by-step explanation:
In the equation y = mx + b, which is the form Ingrid's equation is in, the m stands for the rate of change. If the water level is decreasing, the rate at which it is decreasing is what goes in for m. The "b" of that equation indicates the starting height of the water, which is 170. The equation should be:
y = -4x + 170, negative because the water is decreasing.
Answer:
Part 1 is 420-10 and 210-5, part 2 is 200-10, and 300-15, etc.
Step-by-step explanation:
If this is what I think it is then you're just going to want to divide the first number by the second then once you get all four answers for each part you'll be able to see which ones match. Such as in part 1 you have:
340 and 20 which divides to get 17
420 and 10 which divides to get 42
450 and 30 which divides to get 15
210 and 4 which divides to get 42
Since the second and fourth row both have solutions of 42 they both have equivalent rates.
Hopefully this is what that assignment is asking!
Answer:
· Line segment A'B', whose endpoints are (4, -2) and (16, 14) is the image of AB after a dilation of 1/2 centered at the origin. What is the length of AB? (4) 40. You could either find the length and double it (the image is 1/2 the original) or you can double the x- and y-values and then find the length. Your choice.

Answer:
y=1/2x+4
Step-by-step explanation:
change of x=2-(-4)=6
change of y=6-3=3
slope=3/6 or 1/2
y intercept=5
y=1/2x+5
