Answer:
The lines are perpendicular because perpendicular lines have slopes that are opposite reciprocals. To compare the slopes, you can rewrite the second equation in slope-intercept form as y = (–1/3)x + 1. The slope of the given line is 3, and the slope of the second line is –1/3. These have a product of –1, which means they are opposite reciprocals. Thus, the two lines are perpendicular.
Step-by-step explanation:
I don't need to explain.
It is perpendicular. Because 3x + 9y = 9 in slope-intercept form would be -1/3x + 1, -1/3x would be the opposite of 3x. Therefore, it is perpendicular.
But if you want the sample response instead, here you go
Sample Response: The lines are perpendicular because perpendicular lines have slopes that are opposite reciprocals. To compare the slopes, you can rewrite the second equation in slope-intercept form as y = (–1/3)x + 1. The slope of the given line is 3, and the slope of the second line is –1/3.

a student worked out at the gym continuously for 50 minutes. The graph shows the remaining percentage of the workout f(x) as a linear function of x, the time in minutes
Answer:
Domain: All real numbers greater than or equal to 0 and less than or equal to 50
Range: All real numbers greater than or equal to 0 and less than or equal to 100
Step-by-step explanation
The workout is at 100% at 50 mins. Anything less would be under these two numbers. Since the percentage of workout is on the y-axis, anything between zero and 100 can be possible. The time is on the x-axis, so anything 0 to 50 can be possible.

Winning the jackpot in a particular lottery requires that you select the correct three numbers between 1 and 44 and , in a separate drawing, you must also select the correct single number between 1 and 41. Find the probability of winning the jackpot.
Answer:
[tex]\frac{1}{3,492,544}[/tex]
Step-by-step explanation:
Since winning the lottery as described in the question is a series of events that need to occur in a sequence in order for it to be a winning ticket then this is a dependent event. Therefore to find the probability of actually winning we multiply the probability of getting each number which is calculated by dividing the amount of times the number appears by the total amount of numbers.
For example the first three numbers are 1 out of 44 therefore the probability of hitting just one correct number is [tex]\frac{1}{44}[/tex] ... now we multiply
[tex]\frac{1}{44} * \frac{1}{44} * \frac{1}{44} * \frac{1}{41} = \frac{1}{3,492,544}[/tex]
(Multiplying fractions is simply multiplying the numerators together and then the denominators together) Finally we see that the probability of actually winning the jackpot is [tex]\frac{1}{3,492,544}[/tex]

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?
Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra.
Answer:
Step-by-step explanation:
Y=8(32)+12
Y=256+12
Y=268 (Sandra)
Y=8(24)+12
Y=192+12
Y=204 (Bela)
204+268=472

|x-4|=6x+16 solve equation please
Step-by-step explanation:
|x-4|=6x+16 To find the absolute value :
x - 4 = 6x + 16 or x - 4 = -6x - 16 for first equation
x - 4 = 6x + 16 export like terms to the same side of the equation
-4 - 16 = 6x - x (The terms chages signs from negative to positive and from positive to negative when exported to the other sideof the equation)
-20 = 5x divide by 5
-4 = x
For the second equation
x - 4 = -6x - 16 export like terms to the same side of the equation
x + 6x = -16 + 4
7x = -12
x = 1.7 approximately
