Answer:
(a) 6
(b) 12
(c) 18
(d) The ratios are all equal.
Step-by-step explanation:
I assume that -5 goes with -11, -4 goes with -5, -3 goes with 1, etc.
(a) Look at the points (0, 19) and (1, 25). The inputs are 0 and 1, so the inputs are 1 unit apart since 1 - 0 = 1. Now look at the outputs. They are 19 and 25, and 25 - 19 = 6. The difference of outputs is 6 for a difference of inputs of 1.
(b) Look at points (0, 19) and (2, 31). The inputs are 2 units apart since 2 - 0 = 2. The outputs are 12 units apart since 31 - 19 = 12.
(c) Look at points (0, 19) and (3, 37). The inputs are 3 units apart since 3 - 0 = 0. The outputs are 18 units apart since 37 - 19 = 18.
(d) In part (a), with inputs 1 unit apart, the ratio of output difference to input difference was 6/1. In part (b), with inputs 2 units apart, the ratio of output difference to input difference was 12/2 which is the same as 6/1. In part (c), with inputs 3 units apart, the ratio of output difference to input difference was 18/3 which is the same as 6/1. The ratios are all equal.
Answer:
8-(-8) = 8+8
8-8 = 8+(-8)
-8-(-8) = -8+8
-8-8 = -8+(-8)
10-9 = 10+(-9)
10-(-9) = 10+9
Step-by-step explanation:
Remember that if the signs are equal +,+ or -,- , they are positive (+)
if the signs are different like +,- or -,+ then they are negative (-)
66+6x 6 times 11 is 66 6 times x is 6x

Answer:
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Step-by-step explanation:
Total cost [Pool] = Fixed (membership) cost + Variable cost (per visit)
<u>Intercept</u> is part at which equation line intersects x or y axis. In pools case, it is fixed (membership) cost. <u>Slope </u> is change in y due to change in x. In pools case, it is variable cost (per visit)
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
where V = number of visits.
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
