Hello :
the standard form ( X^2+4X-3X^3+6 ) is : -3X^3+X^2+4X+6
Answer:
-∞ <=x<=∞
(Any value from -∞ to ∞)
Step-by-step explanation:
When y = 3,
x can be any value between -infinite to infinite
Answer:
more than 90° or less than 180°
Answer:
B
Step-by-step explanation:
|-4 + 1| = |-3| = 3
|-4 - 1| = |-5| = 5
The distance is 5, so the second equation should represent the problem.
Answer:
Step-by-step explanation:
5x + 13y = 232
12x + 7y = 218
For each choice:
a) The first equation can be multiplied by –13 and the second equation by 7 to eliminate y. So we have
- 65x - 169y = - 3016
84x + 49y = 1526
Can not eliminate x and y.
b) The first equation can be multiplied by 7 and the second equation by 13 to eliminate y. So we have
35x + 91 y = 1624
156x + 91y = 2834
Can not eliminate x and y if we ADD.
<em>(If we subtract, this is Yes)</em>
<em></em>
c) The first equation can be multiplied by –12 and the second equation by 5 to eliminate x.
-60x - 156y = - 2784
60x + 35y = 1090
The answer is YES
d) The first equation can be multiplied by 5 and the second equation by 12 to eliminate x.
25x + 65y = 1160
144x + 84y = 2616
Can not eliminate x and y
The final answer is C
