Answer:
1. c.
2. a.
3. b.
Step-by-step explanation:
Remember f(x) = y
1. f(x) = y = 2/5x+8
2. f(x)= y - 8 = x => y = 8 +x
3. f(x) = y = x - 8
Answer:
(-4, 2)
Step-by-step explanation:
By looking at the graph, the solution to the system of linear equations will always be where they intercept. If they both are the same line it means that there are infinite solutions, and if they don't intercept at all, that means there are no solutions.
Answer:5.9-6.2x
Step-by-step explanation:
a=1.4-2x
b=-0.2x+1.7
3a+b
=3(1.4-2x)+(-0.2x+1.7)
=4.2-6x-0.2x+1.7
=4.2+1.7-6x-0.2x
=5.9-6.2x
Answer:
The biggest common factor number is the GCF number. So the greatest common factor 72 and 80 is 8
Step-by-step explanation:
6x + 2 - 2 = 14 - 2
6x/6 = 12/6
x = 2
