hope I'm right but either 2 or 4 i can kinda go either way
Answer:
9
Step-by-step explanation:
volume of rectangle is length x width x height. inverse operations makes it 5 times 6 = 30. 270 divided by 30 is 9. hope this helped! :))
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
It's kind of like division and mutliplycation I guess
2.76 pounds of rice because you can divide 11.35 by 4.11
