Hi there! I can help you! The slope-intercept formula is y = mx + b, where m = slope, b = y-intercept, and y and x remain unfilled. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the values of the first coordinate from the second coordinate. Let's use the points (26, -12) and (30, -24). Set it up like this:
-24 - (-12)/ 30 - 26
-24 + 12 is -12. 30 - 26 is 4. -12/4 is -3. The slope is -3. Now, let's solve for the y-intercept. 0 will be filled in as the x value. We will use one of the points on the line to help answer this question. Let's use the point (26, -12). The problem becomes -12 = -3(26) + b. Now, let's solve. -3 8 26 is - 78. Now, we add 78 to isolate the b. -12 + 78 is 66. There. b = 66. The formula for the table in y-intercept form is y = -3x + 66.
Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: ![a_1=5](https://tex.z-dn.net/?f=a_1%3D5)
Second term: ![a_2=3](https://tex.z-dn.net/?f=a_2%3D3)
Common difference is
![d=a_2-a_1](https://tex.z-dn.net/?f=d%3Da_2-a_1)
![d=3-5](https://tex.z-dn.net/?f=d%3D3-5)
![d=-2](https://tex.z-dn.net/?f=d%3D-2)
Now, the explicit formula for an arithmetic sequence is
![a_n=a+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-1%29d)
where, a is first term and d is common difference.
Putting a=5 and d=-2, we get
![a_n=5+(n-1)(-2)](https://tex.z-dn.net/?f=a_n%3D5%2B%28n-1%29%28-2%29)
It can also be written as
![a_n=5-2n+2](https://tex.z-dn.net/?f=a_n%3D5-2n%2B2)
![a_n=7-2n](https://tex.z-dn.net/?f=a_n%3D7-2n)
Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is
or
and domain is all interest greater than or equal to 1.
Answer:
75% is equal to 3/4
Step-by-step explanation:
Why or How?
All you have to do to find a percentage is take 3 and divide it by 4. That will equal .75. Now, multiply that by 100 and you will get 75%.
3/4=
.75=
.75*100=
75%
