Part A: One solution because the lines intersect one time.
Part B: (3,4) or x=3 and y=4 (depending on how you have to write it)
Step-by-step explanation:
let the first number be x
let the second number be y
½ of the first number= ½x
Double the second; 2*y=2y
the sum... that is ½x+2y=14
Answer:
11.57
Step-by-step explanation:
We have a simple formula to solve this:
where
SS is sum of squares
s^2 is the variance, and
n is the number of data points
We are given all the info to find out s^2. Hence,
Answer:
<h2>B. LN ≅ XZ</h2><h2>C. ∠Y ≅ ∠M</h2><h2>E. MN ≅ YZ</h2>
Step-by-step explanation:
CPCTC: Corresponding Parts of Congruent Triangles are Congruent
If ΔLMN ≅ ΔXYZ, then:
B. LN ≅ XZ
C. ∠Y ≅ ∠M
E. MN ≅ YZ
<em>Corresponding sides:</em>
<em>LN → XZ</em>
<em>LM → XY</em>
<em>MN → YZ</em>
<em>Corresponding angles:</em>
<em>∠L → ∠X</em>
<em>∠N → ∠Z</em>
<em>∠M → ∠Y</em>
