Step-by-step explanation:
6x-11+8x-29+3x-1= 180
17x-41= 180
17x = 139
x= 8.17
m<K = 36.4°
Answer:
The slope or gradient of the line L will be: m = 3/8
Step-by-step explanation
We know that the slope-intercept form of the line equation
where m is the slope or gradient and b is the y-intercept
Given the equation of the line
Let us solve for 'y' to write the equation in the slope-intercept form
Add -3x to both sides
simplify
subtract 20 from both sides
simplify
Divide both sides by -8.
Thus, comparing with the slope-intercept form
Thus, the slope or gradient of the line L will be: m = 3/8
Are you sure this is the COMPLETE problem?
When x is 0, y is -9. (0,-9). When y is 0, x is 9/6. (9/6,0)
Answer:
5 minutes.
Step-by-step explanation:
We have been given that the number of minutes needed to drain a bathtub, m, varies inversely as the rate of draining, r.
We know that two inversely proportional quantities are in form , where y is inversely proportional with x and k is constant of proportionality.
Upon substituting our given variables in inversely proportion, we will get:
Let us find constant of proportionality using our given information.
So our required equation would be .
Now, we will substitute in our equation to solve for time.
Therefore, it will take 5 minutes to drain the bathtub at a rate of 32 liters per minute.
