F(x) = 10 - 4x
You must know that f(x) is technically "y" (the right side of the ( not this place ,this place ) )
A) (2, -18)
f(x) = 10 - 4x
-18 = 10 - 4(2)
WRONG!!
B) (18, -2)
f(x) = 10 - 4x
-2 = 10 - 4(18)
WRONG!!
C) (-2, 18)
f(x) = 10 - 4x
18 = 10 - 4(-2)
18 = 10 + 8 (two negatives numbers multiplied together=positive number)
18 = 18
Correct!
your answer is <span>C

Answer: -2
Step 1: Write an equation
Before we are able to solve, we need to write an equation. We can do this by breaking down the equation. We are told to find the sum of -4 and the difference of another two numbers. Sum means addition, so we will add -4 to the difference of 3 and 1. Because we are adding to the difference, we will put 3 and 1 inside of parentheses, and find the difference before we add. Knowing this, we can write the equation. Let’s do this now.
-4+(3-1)
Step 2: Solve
Now that we have the equation we can solve for the answer. Let’s start by finding the difference, as indicated by the parentheses. After that, we can find the sum of that number and -4 by adding them together. We can do this now.
-4+(3-1)
-4+2
-2
This is your answer! The sum of -4 and the difference of 3 and 1 is -2. Hope this helps! Comment below for more questions.
Let the price before increase be Rs.100
Then , as the tpercentage increase =25%
Therefore, increase in price =

Answer:
112.5 square feet
Step-by-step explanation:
The scale model is 6 x 3 and the actual patio is 15 x W
By the definition of a scale model,
15/6 = W/3
15 = 2W multiply both sides by 6
15/2 = W divide both sides by 2
Area of the patio = length * width
Area = 15 feet * 15/2 feet = 225/2 square feet = 112.5 square feet
