Answer:
y = 1/2x -2
Step-by-step explanation:
The given equation is in slope-intercept form, so you recognize its slope is -2. The perpendicular line will have a slope that is the opposite reciprocal of that, so is -1/-2 = 1/2.
The y-intercept can be found from ...
b = y -mx . . . . . for line of slope m through point (x, y)
b = -1 -(1/2)(2) = -1 -1 = -2
Then the slope-intercept equation of the perpendicular line is ...
y = 1/2x -2
Answer:
The number of pools clean per hour is 1.5
Step-by-step explanation:
Given as :
The number of pools clean in 8 hours = 12
The number of pools clean in 7.5 hours = 9
Let The number of pools they clean per hours = x
I.e x =
+
Or, x =
Or, x =
∴ x =
I.e x = 1.5
Hence The number of pools clean per hour is 1.5 Answer
Here's how to convert 0.39 to a fraction...
There is not much that can be done to figure out how to write 0.39 as a fraction, except to literally use what the decimal portion of your number, the .39, means.
Since there are 2 digits in 39, the very last digit is the "100th" decimal place.
So we can just say that .39 is the same as 39/100.
So your final answer is: 0.39 can be written as the fraction 39/100 (ALREADY SIMPLIFIED)
