No it isn't. You can determine if a point is by putting the coordinate values in for x and y.
(2)+2(1)=5
2+2=5
4≠5
For the answer to the question above, I'll provide my solutions below.
x² + 4 = 0
<span> - 4 - 4
</span> x² = -4
x = +2i
x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
2(1)
x = 6 +/- √(36 - 4)
2
x = <span>6 +/- √(32)
</span> 2
x = <span>6 +/- 2√(2)
</span> 2
x = 3 + √(2)
x = 3 + √(2) x = 3 - √(2)
I hope this helps.
Answer:
u = -v + w + x
Step-by-step explanation:
Solve for u:
x = u + v - w
x = u + v - w is equivalent to u + v - w = x:
u + v - w = x
Subtract v - w from both sides:
Answer: u = -v + w + x
Since perpendicular lines have their slopes as negative reciprocals, the negative reciprocal of the given slope (3) is -1/3. Therefore the a value is -1/3.
Answer:
Henri invested $ 4,500 in bonds and $ 19,500 in stocks.
Step-by-step explanation:
Given that Henri has $ 24000 invested in stocks and bonds, and the amount in stocks is $ 6000 more than three times the amount in bonds, to determine the amount that Henri invested in stocks (S) and the amount he invested in bonds (B), the following calculations must be performed:
6000 + 3B + B = 24000
3B + B = 24000 - 6000
4B = 18000
B = 18000/4
B = 4500
S = 6000 + 3x4500
S = 6000 + 13500
S = 19500
Thus, Henri invested $ 4,500 in bonds and $ 19,500 in stocks.
