The point-slope form of a line:
We have the points (-9, -5) and (2, -4). Substitute:
The standard form of a line:
<em>multiply both sides by 11</em>
<em>subtract 9 from both sides</em>
<em>subtract 11y from both sides</em>
Answer:
Step-by-step explanation:
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is y2-y1
x2-i1
Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is y=x/7+15/7
We are given function f(a) = 1.07a for total amount including sales tax.
g(b) = b+50 total cost including delivery.
We need to write function g(f(a)).
g(f(a)) = g of f(a).
We need to substitute function f(a) in g(b) function for b.
g(f(a)) = g(1.07a) = 1.07a +50.
<h3>Therefore, g(f(a)) = 1.07a +50.</h3>
We are given mattress price a = $1125.
In order to find the total cost including delivery charges, we need to plug a= 1125 in the above function 1.07a +50.
Plugging a= $1125, we get
g(1125) = 1.07a +50 = 1.07*1125 +50 = 1203.75 +50 = 1253.75.
<h3>Therefore, total cost including delivery charges is $1253.75.</h3>
H=270/45
To find how many hours it takes to read the rest of the book, you have to divided the remainder of pages (270) by how many pages are read in a hour (45)
Answer:
3x+2x+a=180 degree(being linear pair)
5x+25=180
5x=180-25
x=155/5
x=31
