Answer:
3X+5Y=68 MULTIPLY BY 4
3Y-4X=6 MULTIPLY BY 3 & ADD.
12X+20Y=272
-12X+9Y=18
-----------------
29Y=290
Y=290/29
Y=10 ANS.
Step-by-step explanation:
It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm


An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).
1, it is shifted 4 units up
Answer:
<h2>3 + 4(n - 1)</h2>
Step-by-step explanation:
let r be the common differenc of the sequence
Term 12 - Term 7 = (12 - 7)r
then
47 - 27 = 5r
then
20 = 5r
then
r = 4
term 7 = term 1 + (7 - 1)r
then
27 = term 1 + 6r = term 1 + 24
then
Term1 = 27 - 24 = 3
<em><u>therefore </u></em>
the standard explicit formula of the sequence is :
term 1 + (n - 1)r = 3 + 4(n - 1)
(13-2x)(13-2x)
(13+-2x)(13+-2x)
(13)(13)+(13)(-2x)+(-2x)(13)+(-2x)(-2x)
169-26x-26x+4x^2
4x^2-52x+169
