The answer to this question should be 145
Answer:
<em>2.5</em>
Step-by-step explanation:
y2 - y1 = top
x2 - x1 = bottom
<em>y2 = -5</em>
<em>y1 = -7.5</em>
<em />
<em>x2 = -2</em>
<em>x1 = -3</em>
<em />
<em />
-5-(-7.5) = 2.5
-2-(-3) = 1
2.5 over 1 = 2.5
Reflection of a function
reflection of f(x) about x-axis
So
1. 3/6 = 1/2
2. 5/6
3. 3/6 : 3/6 = 3 : 3
4. 3/6 : 3/6 = 3 : 3
5. 5/6 : 1/6 = 5 : 1
7. 3/6 × 1/2 = 1/4
To solve this you need to use the formula for Chord-Chord length. You need to know it, it is ab=cd. with this, we can plug numbers in.
a=30
b=x+1
c=2x-6
d=21
So our new equation is:
30(x+1)=21(2x-6)
30x+30=42x-126
156=12x
x=13
This isn't what the question is askign for though, it wants YZ
Which is A+B or 30+x+1 or 21+13=34.
YZ=34
