Answer:
x is horizontal, at the bottom(left to right), and y is vertical, going up and down
Step-by-step explanation:
see above
Answer:
No solution.
Step-by-step explanation:
3(n + 4) = 3n + 11
Distribute on the left side.
3n + 12 = 3n + 11
Subtract 3n from both sides.
12 = 11
Since 12 = 11 is a false statement, there are no solutions.
Answer:
(143/74, -65/148)
Step-by-step explanation:
We have the equations:
4x - 12y = 13
14x + 32y = 13
Let's use elimination, so multiply the first equation by 8 and the second equation by 3:
8 * (4x - 12y = 13) ⇒ 32x - 96y = 104
3 * (14x + 32y = 13) ⇒ 42x + 96y = 39
Add those two equations:
32x - 96y = 104
+ 42x + 96y = 39
________________
74x + 0y = 143
Divide both sides by 74:
x = 143/74
Plug this into an equation to find y:
4x - 12y = 13
4 * (143/74) - 12y = 13
12y = 572/74 - 13 = -390/74
y = -65/148
The answer is (143/74, -65/148).
Answer:
it is A
Step-by-step explanation:
35+20 = 55
If x is the length of the third side, then 15<x<55 (notice how the endpoints are NOT included)
166.5
area a is multiplied by y. Aka length times width
