Answer:
y = 7
Step-by-step explanation:
x=4 is a vertical line that goes through the point x=4. y value of this graph changes while x value will be 4 at every point of the graph.
A line perpendicular to this will be a horizontal line with a fixed y value and the x value will change.
The coordinates of the point of which the line has to pass is given as (5,7). Which means the y coordinate of this line is 7.
As we have established that this line has to have same y value at each point just like x=4 has same x value at each point, we can say the equation of the line is y=7.
Solution:
Equation of line perpendicular to , x=4 is
y +k=0
As, keep in mind , the equation of line perpendicular to , ax + by +c=0 is b x - a y +c=0
As, given the line perpendicular to, x =4, passes through the point (5,7).
So, y+k =0, passes through (5,7).
→ 7 +k=0
→ k= -7
So, line perpendicular to x=4, which passes through the point (5,7) is →y-7=0 that is y=7.
Option (C) →y=7
Answer: n = 4
Step-by-step explanation:
n is always equal to the number of times 10 could be raised to so as to make a total of the number in question.
Hi
7|9n+10|=70
First divide both sides by 7
7(|9n+10|)/7= 70/7
|9n+10|=10
Now we need to find the absolute value
|9n+10=10
We know that either 9n+10=10 or 9n=10=-10
We have to possibility
The first possibility is
9n+10=10
Now we need to subtract 10 to both sides so we can find the value for n for the possibility 1
9n+10-10=10-10
9n=0
Now divide both sides by 9 so we can find the value for N
9n/9=0/9
n= 0
Now let's go for possibility 2
9n+10=-10
We gonna do the same thing for possibility 2 by subtract 10 from both sides
9n+10-10=10-10
9n=-20
Divide both sides by 9 so we can find the value for N
9n/9=-20/9
n= -20/9
Answer ; N=0 or N=-20/9
I hope that's help and good luck :)
your work.
Answer:
13 , 24 , 14
Step-by-step explanation:
Note that technically there are two patterns. Each one adds 1.
The first pattern starts with 11. The third number is 12, which means that the fifth number will be 13, and the 7th number will be 14.
The second pattern starts with 22. The 4th number is 23, which means the sixth number will be 24.

Easy, it's going by adding 11's 11+11=22 than it subtracts by 10=12 and it keeps repeating until it's done.
