Let's call the first number x, and the second number y. Putting what you have said into equation form:
Subtracting one equation from another gives:
If x = -5,
So the first number is -2, the second number is 9
17156 is the answer! Do 449x25, 489x9 and 510x3
It should be greater not lesser
If Bryan’s and Sequola’s group work together it would take them both 4 hours to build a garage because 16 - 12 = 4.
Hope this helps ;-)
To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67
