Answers
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

There are 5 multiples of 5 that are contained in 1-25.
Our current fraction is 5/25, as we have 5 multiples of 5, and 25 total numbers.
Since we don't have an answer choice that matches our answer, we may need to simplify.
Divide both sides by 5.
5 / 5 = 1
25 / 5 = 5
Our new and simplified answer is 1/5.
Your answer is C.) 1/5.
I hope this helps!

Answer:
B. coincident
Step-by-step explanation:
An coincident system of equations means that it has infinite solutions, because one line is on the other one. This happens when their equation are the same, or their "parent" line is the same.
So, given equations are:
6x + 4y = 2 and 3x + 2y = 1
Observe that if we divide the first by 2, we have
As you can see, using the first equation, we found that it has the same "parent" equation than the second equation. In other words, they are basically the same. This means that they represent the same line, so, the system is coincident and they have infinite solutions.
After analyzing the data provided in this question one can conclude that they are coincident. For the first system equation we have: 6x + 4y = 2. If we divide everything by 2 we will get: 3x + 2y = 1. Coincident means the same line.
The answer is choice B). Coincident.
I hope it helps, Regards.
