Answer:
A)29 and B) 21,
Step-by-step explanation:
First,in the sequence
, the parameter
must to be a integer.
Second, we need to solve the equations by
.
![n=(a_n+7)/4](https://tex.z-dn.net/?f=n%3D%28a_n%2B7%29%2F4)
All the option in the problem represent an
Then, we need to prove all number in the options, if the result is a integer number, this option can be part of the sequence.
For A)
![n=(29+7)/4=9\\](https://tex.z-dn.net/?f=n%3D%2829%2B7%29%2F4%3D9%5C%5C)
For B)
![n=(21+7)/4=7\\](https://tex.z-dn.net/?f=n%3D%2821%2B7%29%2F4%3D7%5C%5C)
For C)
![n=(20+7)/4=6.75\\](https://tex.z-dn.net/?f=n%3D%2820%2B7%29%2F4%3D6.75%5C%5C)
For D)
![n=(28+7)/4=8.75\\](https://tex.z-dn.net/?f=n%3D%2828%2B7%29%2F4%3D8.75%5C%5C)
Only A) and B) only A and B meet the requirement
Answer:
x=0.625
Step-by-step explanation:
-(-2x+1)=9-14x
distribute:
2x-1=9-14x
add 1 to both sides
2x = 10-14x
add 14x to both sides
16x=10
divide by 16 to isolate x
x = 0.625
check:
-(-2(0.625)+1) = 9-14(0.625)
0.25 = 0.25
Answer:
Step-by-step explanation
just plug in 0 for z so it would change to -2<6
The slope-intercept form:
![y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5C%5C%5C%5Cm%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
m - slope
b - y-intercept → (0, b)
We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.
Calculate the slope:
![m=\dfrac{1-(-9)}{0-(-9)}=\dfrac{10}{9}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B1-%28-9%29%7D%7B0-%28-9%29%7D%3D%5Cdfrac%7B10%7D%7B9%7D)
Answer: ![y=\dfrac{10}{9}x+1](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B10%7D%7B9%7Dx%2B1)
Hello Bri,
If you are talking about a boundary line on a coordinate plane, the best way to determine which side to shade is to start by selecting a coordinate point (x, y) that is not on the line.
Then, substitute those values into your inequality. Simplify the inequality. If the resulting statement is true, then shade the side with your point. If the resulting statement is false, then shade the other side.
Testing a point like this shows the side of the inequality that is the solution and needs to be shaded.
Good luck!
