<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
I think it would be 12(2-3)
Hope this helps!
<span>A city council wants to build a public park. Which of these taxes is it most likely to use to fund its effort?
</span><span>c. Property Tax</span>
The correct answer is that a factor of f(x) is (x+1)
This is due to the zero product property, which states that if two binomials multiply to 0, then one of its factors must equal 0.
(x+1) must equal 0.
(x+1)=0
x=-1
If (x-1)=0, then x would equal 1 instead of -1 which is what the question is asking for.
Answer:
C
Step-by-step explanation:
a = 4
b = 5
c = 2
C = arccos((a² + b² - c²) / 2ab)
C = arccos((16 + 25 - 4) / 2(4)(5))
C = arccos(37 / 40)
C = 22.33°
2abcosC
2(4)(5)cos(22.33)
40(0.925)
37
