Answer:
1 and 2 SORRY IF I AM WRONG
Domain: {10, 12, -8, 6}
Range: {-3, 3, -7, -1}
There is one value of <em>y</em><em> </em>for every value of <em>x</em>.
This relation is a function.
I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:
-c^2-4c+21
From here, we’ll factor out a -1 so that we have:
-(c^2+4c-21)
Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:
(c + (-3))(c + 7)
(c - 3)(c + 7)
And adding back on the negative from a few steps earlier:
-(c - 3)(c + 7)
To simplify, we need to find a number that can divide both the numerator and denominator equally. Can you find a number that will do this? I can't. So it is already simplified.
<h2>Answer:
</h2>
The length of VW is 23°
<h2>Step-by-step explanation:
</h2><h3>Known :
</h3>
<h3>Asked :
</h3>
VW = ?
<h3>Solution :
</h3>
Since the UV line and UX line has the same length, so the VW line should have the same length as the WX line.
VW = WX
23 = 23
<h3>Conclusion :
</h3>
The length of VW is 23°
