This is the concept of algebra. Given that f(x)=3x+10x and g(x)=5x-3, then:
(f+g)(x)
=f(x)+g(x)
=3x+10x+5x-3
=18x-3
the answer is B. (f+g)(x)=(18x-3)
Answer:
10/12 also 5/6
Step-by-step explanation:
The graph of f(x) has a slope of 1/1 and a y intercept of -6. To graph, place a point at (0,_6). Then move up 1 and over 1. This will give another point at (1,-5). Draw a line through the points.
The graph of g(x) has a slope of 1/1 and a y intercept of 6. To graph, place a point at (0,6). Then move up 1 and over 1. This will give another point at (1,7). Draw a line through the points
lines are parallel since slopes are the same.
h(x) = x-6+x+6= 2x or 2x+0. This line has a slope of 2/1 and a y intercept of 0. To graph, place a point at (0,0). Then move up 2 and over 1. This will give another point at (1,2). Draw a line through the points.
