Line s and point T are given as graphed.
Zepler [3.9K]

Answer:

The slope is undefined

Step-by-step explanation:

we have that

The equation of the line s is equal to

x=3

This is a vertical line (parallel to the y-axis)

The slope is undefined

Because

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(3,3)\ (3,-2)

Substitute the values

m=\frac{-2-3}{3-3}

m=\frac{-5}{0}  ------> is undefined

The point T is (5,-1)

The equation of the line parallel to the line s that passes through the point T, will be a vertical line and the equation  is equal to the x-coordinate of point T

therefore

The equation is

x=5

Jane is paid 14.85 an hour for regular 40 hour work week. her overtime pay for any hours over 40 per week is 1.5 times her regul
klasskru [66]

Around 6 hours (exact decimal would be 5.99865). I did this by multiplying 14.85*40 (getting 594). After that, I subtracted 594 from 727.65 (getting 133.65), then multiplying 14.85 by 1.5, getting 22.28, and then, I did 133.65/22.28, getting 5.99865, which I rounded to 6.

The difference of a number and fifteen is two. Write and Algebra Sentence then solve the number.

x - 15 = 2

x = 2 + 15

x = 17

-------------------------

check

17 - 15 = 2

2 = 2

If s and t are integers greater than 1 and each is a factor of the integer n, which of the following must be a factor of n st ?
yulyashka [42]

Answer:

A) None

Step-by-step explanation:

1) s^t shoudnt neccesarily be a factor of nst, for example, if s = 3, t = 4, and n = 12, then both s and t are factors of n, but 3^4 = 81 is not a factor of nst = 144.

2) (st)^2 shoudnt neccesarily be a factor of nst. Let s be 4, let t be 6, and let n be 12. Then n is a factor of both s and t, but (st)^2 = 24^2 is not a factor of nst = 12*24. In fact, it is a greater number.

3) Again, s+t isnt necessarily a factor of nst, let s be 2 and t be 3. Then both s and t are factor of n = 12. However 5 = s+t is not a factor of nst = 72.

So, neither of the three options is guaranteed to be a factor of nst. In fact, for s = 4, t = 6, and n = 12, none of the three options are valid.
