Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)

Step-by-step explanation:
volume for a rectagular prism is length x width x height
6 x 3.9 x 13.2 = 308.88
Y = 3x + 4
y = 3x + 7
3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.
or look at it this way..
y = 3x + 4
y = 3x + 7
both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution
Answer:
4x − 30 = ≤12
Step-by-step explanation:
4x − 30 = ≤12
+30 on both sides
4x≤42
divided by 4 on both sides
x≤10.5
