PLEASE HELP WILL GIVE 15 POINTS

Answer:
Step-by-step explanation:
Hello, when you have an equation like y = ax+b you know that this is a line.
In this example, the function is defined in two different intervals.
For x < 1 this is the line y = 4 + x
and for x>=1 this is the line y = 4 - 2x
At the frontier, x= 1, we have 4+1=5 on one side and 4-2=2 on the other side, we we expect a "jump" in the graph.
Except that "jump"you just have to draw lines, so if you have two points you can draw them right.
For x<1, the line is passing by (-4,0) and (0,4)
And you have to stop for x<1 so the point (1,5) is not on the graph.
for x>=1 the points (1,2) and (2,0) are on the graph and we just have to draw the line.
I attached the graph.
Thanks

Answer:
7/40 feet
Step-by-step explanation:
Solve using proportions:
Find the scale factor by dividing the numerators 25 by 1/8.
25 ÷ 1/8 = 200 This is the common ratio
To get from the top left number to the top right number, you divide 25 by 200.
To get from the bottom left number to the bottom right number, you divide 35 by 200.
35 ÷ 200 = 0.175
1/8 of an inch represents 0.175 feet.
To find 0.175 in fraction form, reduce 35/200 to its lowest terms.
35/200 = 7/40
1/8 of an inch represents 7/40 feet.
