Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.
The number of terms in the given arithmetic sequence is n = 10. Using the given first, last term, and the common difference of the arithmetic sequence, the required value is calculated.
<h3>What is the nth term of an arithmetic sequence?</h3>
The general form of the nth term of an arithmetic sequence is
an = a1 + (n - 1)d
Where,
a1 - first term
n - number of terms in the sequence
d - the common difference
<h3>Calculation:</h3>
The given sequence is an arithmetic sequence.
First term a1 =
= 3/2
Last term an =
= 5/2
Common difference d = 1/9
From the general formula,
an = a1 + (n - 1)d
On substituting,
5/2 = 3/2 + (n - 1)1/9
⇒ (n - 1)1/9 = 5/2 - 3/2
⇒ (n - 1)1/9 = 1
⇒ n - 1 = 9
⇒ n = 9 + 1
∴ n = 10
Thus, there are 10 terms in the given arithmetic sequence.

Question: If the first and the last term of an arithmetic progression with a common difference are
,
and 1/9 respectively, how many terms has the sequence?
<h2>Steps:</h2>
So to solve for a variable, we must isolate such variable onto 1 side of the equation. In this case, we must isolate the x variable. Firstly, subtract both sides by Fy:
![Dx=M-Fy](https://tex.z-dn.net/?f=Dx%3DM-Fy)
Next, divide both sides by D:
![x=\frac{M-Fy}{D}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7BM-Fy%7D%7BD%7D)
<h2>Answer:</h2>
<u>Your final answer is
</u>
Answer:
7
Step-by-step explanation:
|24| - |-17|
The absolute value of 24 is 24 so,
24 - |- 17|
and the absolute value of -17 is 17 so all you have to solve for is
24 - 17
which is 7
hope this helps :)
Answer:
The zeros are x=5 and x=3
Step-by-step explanation:
x^2-8x+15
To find the zeros, we set the equation equal to zero
x^2-8x+15 =0
Factor the equation
What 2 numbers multiply to 15 and add to -8
-5*-3 = 15
-5+-3 = -8
(x-5) (x-3) =0
Using the zero product property
x-5 =0 x-3 =0
x=5 x=3
The zeros are x=5 and x=3
