Domain is the x value. So you would just plug in every value in the domain set into the f(x) function.
5 (-2) + 4 =
-6
5 (3) + 4 =
19
5 (5) + 4 =
29
Your answer is B.
Step-by-step explanation:
If the second piece is x inches long, then the first piece is 5x inches long. The total length is 192 inches, so:
x + 5x = 192
6x = 192
x = 32
The lengths of the two pieces are 32 inches and 160 inches.

Step-by-step explanation:
Answer:
y=2/7x+19/7
Step-by-step explanation:
Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7
Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:
y=2/7x+b
3=2/7(1)+b
3=2/7+b
21/7=2/7+b
19/7=b
Therefore, our final equation is y=2/7x+19/7
