Answer:
we have
f(x)=x-6f(x)=x−6 -----> equation A
This is a linear equation with slope m=1m=1 and a y-intercept equal to -6−6
g(x)=x+6g(x)=x+6 -----> equation B
This is a linear equation with slope m=1m=1 and a y-intercept equal to 66
The function f(x) and g(x) are parallel lines
we know that
h(x)=f(x)+g(x)h(x)=f(x)+g(x)
Substitute
h(x)=x-6+x+6h(x)=x−6+x+6
h(x)=2xh(x)=2x
This is a linear equation with slope m=2m=2 that passes through the origin ( represent a direct variation)

Answer:
The mean increased
Step-by-step explanation:
The mean is the average, add all numbers and divide by total amount.
Old mean: 6
New mean:8
<span>For this case, what you must do is find the area of the two rectangles shown in the figure.</span>
<span> We have then:</span>
<span> Rectangle 1:</span>
<span> A1 = (40) * (18)</span>
<span> A1 = 720</span>
<span> Rectangle 2:</span>
<span> A2 = (24-18) * (40-30)</span>
<span> A2 = (6) * (10)</span>
<span> A2 = 60</span>
<span> The area of the composite figure is:</span>
<span> A = A1 + A2</span>
<span> A = 720 + 60</span>
<span> A = 780 feet ^ 2</span>
<span> Answer:</span>
