Answer:
-9
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A Arithmetic sequence -5 , -14 , -23 ...
And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.
<u>Sequence</u><u> </u><u>:</u><u>-</u><u> </u>
-5 , -14 , -23
<u>Common</u><u> difference</u><u> </u><u>:</u><u>-</u><u> </u>
CD = -14 -(-5) = -14+5=-9
CD = -23-(-14) = -23+14=-9
<u>Hence </u><u>the</u><u> </u><u>common</u><u> difference</u><u> </u><u>is </u><u>(</u><u>-</u><u>9</u><u>)</u><u> </u><u>.</u>
Couch: 2x
love seat: 2x+400
chair: x
total amount: $1565
2x+2x+400+x=1565
5x+400=1565
5x=1165
x= 233
The cost of the chair is $233. The cost of the couch is $466. The cost of the love seat is $866.
Hope this helps!
We can use the vertex form
to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is
Which is D
