Answer:
The answer to your question is c) y = (-2/3)x + 8/3
Step-by-step explanation:
Data
A (-2, 4)
B (1, 2)
Process
1.- Calculate the slope of the line
-Formula
m = (y2 - y1)/(x2 - x1)
x1 = -2 y1 = 4 x2 = 1 y2 = 2
-Substitution
m = (2 - 4) / (1 + 2)
-Simplification
m = -2/3
2.- Find the equation of the line
Formula
y - y1 = m(x - x1)
-Substitution
y - 4 = -2/3 (x + 2)
-Simplify
y - 4 = (-2/3)x - 4/3
y = (-2/3)x - 4/3 + 4
y = (-2/3)x - 4/3 + 12/3
-Result
y = (-2/3)x + 8/3
Answer:
Option A is the answer
Step-by-step explanation:
Toski is building a room having length = 18 feet
Width of the room = 14 feet
Scale has been given as 1 inch = 2 feet
∵ 2 feet = 1 inch
∴ 1 feet =
feet
∴ 18 feet length of the room =
inches
Similarly 14 feet width of the room =
inch
Now we count the small blocks in the given options.
Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.
Option A is the answer.
<span>I believe you MEANT 8/(x^2-25)+9/(x-5) Parentheses in this format are important...the way you typed it means (8/x^2)-25+(9/x)-5 which I doubt you mean. Anyway.
If you factor the first denominator you will see that it is equal to (x+5)(x-5). Division by zero has no meaning so x cannot equal -5 or 5.
If we multiply the second fraction by (x+5) we will have a common denominator of (x^2-25) for the entire equation leaving us with:
(8+9x+45)/(x^2-25)
(9x+53)/(x^2-25)
The second problem is worked in exactly the same way, notice that there is no "solution" as there is no equal sign. This is an "expression" not an "equation".</span>
