Answer:
B
-3
Step-by-step explanation:
B is correct but based on the fact that you selected it I'll assume you know why (comment if you want me to explain it)
Then for two lines to be paralell it means that their lines never intersect
The only way for this to be possible is if the lines have the same slope.
This means that the answer is -3
1. Yes, angles a and b have a common vertex (starting point) and a common side (the line between angle a and b). They do not overlap.
2. No, angles a and b share a common vertex but not a common side.
3. No. Same as above.
4. Yes, anlges a and b share a common vertex and side.
Answer:
1 Hot dog = $2.50; 1 Nacho = $3.00
Step-by-step explanation:

Answer:
347 is the initial spider population
Step-by-step explanation:
y = ab^x
is the formula for exponential growth and decay
a = the initial value
b is the growth or decay rate
b>1 it is the growth rate (b-1) is the percent
0<b<1 it is the decay rate (1-b) is the percent
y = 347(1.2)^x
347 is the initial spider population
(1.2-1) = .2 = 20 % growth rate
