Answer:
y = 2x - 19
Step-by-step explanation:
Graph the points on the table and you'll be able to see the answer. That's how I went about it.
or use m = y^2 - y^1 divided by x^2 - x^1 to find the slope, then solve for the initial value from there
The square numbers smaller than 75 are 1, 4, 9, 16, 25, 36, 49, 64
1+49+25=75 seems to be the only set possible.
1+7+5=13
the answer is 13

Step-by-step explanation:
The cost of using 19 HCF of water is $32.49
Given in the question:
The monthly cost (in dollars) of the water use (in dollars) is a linear function of the amount of water used (in hundreds of cubic feet, HCF)
The cost for using 17 HCF of water is using $32.13
and, the cost of using 35 HCF is $61.83.
To find the cost of using 19 HCF of water.
Now, According to the question:
The cost for using 17 HCF of water is $32.13
and, the cost of using 35 HCF is $61.83.
To find the slope:
(17, 32.13) and (35, 61.83)
Slope = (61.83 - 32.13)/ (35 - 17) = 1.65
We know that:
Formula of slope :
y = mx + b
32.13 = 1.65 x 17 + b
b = 1.14
The equation will be :
C(x) = 1.65x + 1.14
Now, To find the cost of using 19 HCF of water.
C(19) = 1.65 × 19 + 1.14
C(19) = $32.49
Hence, the cost of using 19 HCF of water is $32.49.

Step-by-step explanation:
Well, 3/5 hours equals 30 secs.This means that he started 3:30 hours ago .To find out what time was it you have to subtract 3:30 from the finishing time. So, 10:18-3:30=6:48.If you have any further questions please contact me.
