Answer:
see below
Step-by-step explanation:
All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.
<u>first choice</u>: the y-values have a common difference of -2. This will be matched by a linear model.
<u>second choice</u>: the y-values have a common difference of +2. Again, this will be matched by a linear model.
<u>third choice</u>: the y-values have a common ratio of -2. This will be matched by an exponential model.
<u>fourth choice</u>: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.

Answer:
The answer is 1/3
Step-by-step explanation:
-4/-12 is the same as -4 divided by -12, and a negative divided by a negative will always be a positive; therefore, the answer comes out to be positive.
The price of a flower bouquet is $2.75 according to the information on the question above. This problem can be solved using two linear equations with two different variables based on the transaction. The first equation is 3x +5y= 25.75 and the second equation is 8x+2y=29 which can be simplified as y=14.5-4x. You can find the x by substituting the "y" variable on the first with the second equation resulting in "x =2.75" which is the price of the flower bouquet<span>.</span>
Answer:
Step-by-step explanation:
x + (x+30) + (2x) = 180
4x = 150
x = 37.5°
x+30 = 67.5°
2x = 75°
