Answer:
1. b. The common difference is 0.39
2. no good answer (Zach's method is exponential; Victoria's is linear)
Step-by-step explanation:
1. The differences in mileage are ...
24.39 -24 = 0.39
24.78 -24.39 = 0.39
25.17 -24.78 = 0.39
The common difference is 0.39.
____
2. Zach's monthly times are ...
10, 20, 40, 80
The differences are ...
10, 20, 40
The ratios are ...
20/10 = 40/20 = 80/40 = 2
Zach's times have a common ratio, so are exponential.
__
Victoria's monthly times are ...
35, 50, 65, 80
The differences are ...
15, 15, 15
Victoria's times have a common difference, so are linear.
__
The choices are ...
a. both exponential; common factor . . . . correct for Zach; not for Victoria
b. Zach's is linear (has equal factor) . . . incorrect
c. both exponential; common difference . . . incorrect
d. Victoria's is linear . . . . correct for Victoria
Choice D describes Victoria's method. Choice A is correct regarding Zach's method, but incorrect regarding Victoria's.
Choices B and C are not self-consistent, so are incorrect on their face.
There is no good choice.

Step-by-step explanation:
Answer:
AA similarity (Postulate).
Step-by-step explanation:
The AA Similarity Postulate states that <em>two triangles are similar if all their corresponding angles are congruent, and their corresponding sides are proportional.</em>
In this case:
∡ACE ≅ ∡DBE (Given)
∡BED ≅ ∡AEC (Vertical Angles Theorem)
For Proportionality, you will have to get more information on the measurements of the sides. As side measurements are not given, you cannot use any similarities based on sides to prove the similarities of the triangles.
5) The less than symbol, using x, is <em>x < __</em>. The blank should have the number that comes after, which is <em>-15°F</em>. So, that will look like x < -15°F
6) When something is at most __, that means that __ is the greatest number, which means the inequality looks like <em>x ≤ __</em>. The number that goes into the blank is <em>127 pounds</em>, which makes the whole inequality x ≤ 127 pounds.
7) An inequality is solved similarly to an equation, with a few exceptions.
x - 3 < -15
Subtract: x < -12
That looks like what is shown in the image. The circle is empty because the inequality does not say that it contains -12, so it is skipped. It goes to the left because the inequality shows all numbers less than -12.
