5. Decide whether each table could represent a proportional relationship. If the relationship could be
proportional, what would be the constant of proportionality?
a.
The sizes you can print a photo:
width of photo (inches)
2
height of photo (inches)
3
6
4
5
7
10
8
b.
The distance from which a lighthouse is visible:
distance it can be seen (miles)
6
height of a lighthouse (feet)
20
45
70
+
9
11
95
13
150
16

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

it is x=-4
