Find the scale for how many miles per inch are on the map:
270 miles / 4.5 inches = 60 miles per inch.
On the map every 1 inch equals 60 miles.
12 inches x 60 miles per inch = 720 miles total.
City B and City C are 720 miles apart
You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.

Answer:
-2/5
Step-by-step explanation:
Slope of a line is also called gradient.
Let A(x₁,y₁) and B(x₂,y₂) be points on a certain line;
slope = (y₂ -y₁)/(x₂ - x₁)
In this question the 2 points that lie on the line are: (-5,5) and (0,3)
slope = (3 - 5)/(0 - -5)
= -2/5
Answer:
vertex: (5/6,5)
focus: (- 2/3, 5)
axis of symmetry: y = 5
directrix: x = 7/3
Step-by-step explanation:
use the vertex form to determine the values of a.h. and k and use these values to find the direction the parabola opnes, vertex, foucs, axis of symmetry, and directrix
