Hello,
Let's assume i the number of lines,
u(i) the number of regions:
Answer:
The axis of symmetry is -b/2a
The x-intercept shown is 3 units away from the axis of symmetry.
The other x-intercept also must be 3 units away from the axis of symmetry but on the opposite side.
Subtract 3 from the axis of symmetry.
The other x-intercept is (-b/2a-3,0)
Step-by-step explanation:
The cities are 12.2 miles apart
<u>Step-by-step explanation:</u>
The scale of the map is,
5cm = 10 miles
The distance between the 2 cities in map is 6.2 cm
The actual distance between the 2 cities = (6.2 x 10) / 5
= 62/5
= 12.4
The 2 cities are 12.4 miles apart.
Answer:
B and D
Step-by-step explanation:
A
× 13 = 
= 
= 10 < 13
B
4 × 13 = 52 > 13
C
× 13 = 
= 
= 4 < 13
D
× 13 = 1 × 13 = 13
Band D are equal to or greater than 13
