Answer:
see below
Step-by-step explanation:
The ratio of map distance to actual distance is a constant (for a map of a sufficiently small area).
(0.5 in) / (25 mi) = (map distance between cities) / (725 mi)
Answer:
11.33 or 34/3
Step-by-step explanation:
6x+23+9x−13=180
Step 1: Simplify both sides of the equation.
6x+23+9x−13=180
6x+23+9x+−13=180
(6x+9x)+(23+−13)=180
15x+10=180
15x+10=180
15x+10−10=180−10
15x=170

Answer:
y = -2x-5
Step-by-step explanation:
So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b
To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.
So y=-2x-5.
