X2+3x+1=0
5x+1=0
-1 -1
5x=-1
/5 /5
x=-0.2
The line has 0 slope. This is because the y value didn’t change. Take the change in y (0) and divide it by the change in x (4) you get 0 slope.
Answer:
c= -12
Step-by-step explanation:
36 divided by -3 is -12
Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.
Answer:
The sum of the first nine terms of the sequence is 74.44.
Step-by-step explanation:
Geometric sequence concepts:
The nth term of a geometric sequence is given by the following equation.
In which r is the common ratio.
This can be expanded for the nth term in the following way:
In which 
is the first term.
Or even:
The sum of the first n terms of a geometric sequence is given by:
Finding the common ratio:
![r = \sqrt[5]{\frac{15}{3.645}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7B15%7D%7B3.645%7D%7D)
Finding the first term:
Sum of the first nine terms:
The sum of the first nine terms of the sequence is 74.44.
