Answer:
D
Step-by-step explanation:
The correct answer among the choices give is the first option. To answer the question, we dissect every statement given.
<span>ten times is expressed
</span><span>10 (any expression)
</span>ten times the sum of a number and fourteen
10 (N+14)<span>
is means equal sign
</span>10 (N+14) =<span>
equal to nine times the number
</span><span>10 (N+14) = 9N</span>
1a.) y=0.5x+2
1b.) The 0.5x is the slope. It represents the amount of extra money you are paying (in addition to the automatic $2) per mile. The y-intercept is 2. That represents the amount you automatically pay for that company.
2.a) I forgot how to do point-slope form, but for 2b., the slope is representing the same thing as in 1a. The slope is .65 and it is representing the amount of money you pay (in addition to the automatic $1.75) per mile.
To find the answers to the table question, use the slope intercept formula, y=.65x+1.75 Plug the numbers they are asking about in for x.
Example: Plugging in 3 we get y=(.65)(3)+1.75 which will equal 3.7 so the amount of money you pay after driving for 3 miles is $3.70.

Answer:
We conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.
Step-by-step explanation:
Given the sequence
2, -4, -16, -36,...
- A geometric sequence has a constant ratio 'r'.
Let us compute the ratio of all the adjacent terms
It is clear that the ratio is not constant.
Thus, the given sequence is not a geometric sequence.
Therefore, we conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.
Answer:
Step-by-step explanation:
The first step is to realize that this is a geometric sequence, where each next term in the sequence is 2.5 times larger than the previous. You can confirm this by the fact that 3=1.2*2.5, 7.5=3*2.5, and 18.75=7.5*2.5. Now, you can write the formula, where n is where the number is in the sequence, and a is the number itself. Since 1.2 is the first term in the sequence and the rate of expansion is 2.5, the formula is:
Hope this helps!
