3x - 9y = 15
-9y = -3x + 15
y = (-3/-9)x + (-15/9)
y = 1/3x - 5/3....slope here is 1/3. A perpendicular line will have a negative reciprocal slope.All that means is " flip " the slope and change the sign.
So our perpendicular slope will be : -3 ( I flipped 1/3 and it became 3/1 or just 3...I then changed the sign and it became -3)

so the perpendicular slope is -3

According to (-b/a)
So --9/3=3
(-b/a) is the equation of the slope

If z is an even integer which of the following expressions must represent an odd integer?
ad-work [718]

There is no choice on your list that must represent an odd integer.

If  'z'  is an even integer, then (z-1) and (z+1) must both be odd integers.

Alex787 [66]

Answer:

Zac will finish, Pam won’t

Step-by-step explanation:

Let’s have the individual reading speeds

The individual reading speeds are the number of pages divided by hours taken

For Pam; 126/3 = 42 pages per hour

For Zac; 180/4 = 45 pages per hour

In five hours, Zac would read; 45 * 5 = 225 pages

In five hours, Pam would read 42 * 5 = 210 pages
