Answer: 75 feet²
Step-by-step explanation:
The scale means that for every one unit in the scale drawing, it is 30 units in the actual room. We will convert the dimensions using proportions.
x = 90
-
x = 120
The area of a rectangle can be found by multiplying the length by the width:
A = L * W
A = 90 * 120
A = 10,800 inches²
To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.
10,800 inches² / 144 = 75 feet²
The area of the room, in square feet, is 75 feet².
<h3>Answer: y = 3x+4</h3>
Slope = 3
y intercept = 4
========================================================
Explanation:
Let's find the slope.
The slope is m = 3.
The y intercept is b = 4 due to the point (0,4). The y intercept <u>always</u> occurs when x = 0.
We'll then plug those m and b values into y = mx+b to get the answer y = 3x+4
-----------
As a way to check the answer, plugging x = 0 should lead to y = 4
y = 3x+4
y = 3*0+4
y = 0+4
y = 4
So that works out. Let's try x = 1. It should produce y = 7
y = 3x+4
y = 3*1+4
y = 3+4
y = 7
That works out also. The answer is fully confirmed.
