-16x+144=128
answer is 128x-80
1.) 1/9, 2/18, 3/27
2.) 6/10, 12/20, 9/15
You can split the figure into a top and bottom box.
Top box has the measurements of 3 by 18 by 20. When you multiply those together you get the volume of that box- 1080.
Bottom box has the measurements of 15 by 8 by 8. Multiplied together for the volume is 960.
Adding the top and bottom box together (1080+960) you get a total of 2040 yards cubed.
Usually you will see something like g(x) or f(x)
domain means all the x's
so, think of g(4) meaning g(x=4) and g(4 in the domain).
look for 4 on the domain side
you know that f(x) = y
range means all the y's
so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.
in this case, it's B) 5
The inequality that matches the graph would be C. -3x + 2y ≥ 7.
