Answer:
C. y = 7x + 29 .
Step-by-step explanation:
First find the slope of the given line:
x - 7y = 12
7y = x - 12
y = 1/7 x - 12/7
The slope = 1/7 so the slope of the line perpendicular to this line is
- 1 / -1/7 = 7.
Finding the equation of the required line:
y - y1 = m(x - x1)
y1 = 8 , m = 7 and x1 = -3:
y - 8 = 7(x + 3)
y = 7x + 21 + 8
y = 7x + 29 answer.
7x - 8(-2 + 9) = 112
7x - 8(7) = 112
7x - 56 = 112
7x = 112 + 56
7x = 168
x 168/7
x = 24 <==
Answer:
4xy
Step-by-step explanation:
20x^2 y = 4*5 x^2 y = 2*2*5*x*x*y
16*x*y^2 = 4*4*x*y^2 = 2*2*2*2*x*y*y
what is common in both
2*2*x*y
4xy
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)
