Write the equation of line perpendicular to y = 4 that passes through (5, 2).

Answer:
x=5

Explanation;
y=4 is a horizontal line, and we know this because all we have is the y intercept; 4 (the y-intercept is the point on the line that intercepts the y axis) There is also no x value. This is the equation for a horizontal line:

y=b
B is the y-intercept.

A line perpendicular to a horizontal line would be a vertical line. This is the equation for a vertical line:

x=d
D is the x-intercept (the point on the line that intercepts the x axis)

So to answer the question, we just need to plug the x value of the point (5,2) into x=d.

(5,2)-> 5 is the x coordinate

Therefore, x=5

I hope this helps! Please comment if you have any questions.

Plz help me thx if u do
ivolga24 [154]

Answer:

So, C, and D.. can easily be marked incorrect. This is because in the question it asks, "Atleast 16" This leaves us with answer choice A and B. Answer choice (A), is a closed circle, while answer choice (B) is an open circle.

Closed circles include the number at the end point (less than/greater than/equal to), and open circles do not (less than greater than).

answer choice  A. Closed circle, shifting to the right.

I'm confused can someone help me
Dafna11 [192]

Answer: M∠2 just mean measure of angle 2,

Step-by-step explanation: So I worked it out and the awnser is B.

3 numbers/the degrees of all 3 sides always add up to 180 degrees.

Side 1 is 60 degrees and the left side is 20, so 20 + 60 + 3 (unkown    number) = 180

60 - 20 = 100,

Which point satisfies both ƒ(x) = 2x and g(x) = 3x?
Dvinal [7]
Ƒ(x) = 2x and g(x) = 3x?

The question means at which points (or coordinates)  f(x) & g(x) intercepts.
In this case you proceed as follows:
f(x) =g(x)==> 2x = 3x or 0 = x if x = 0 , y also =0 then both graphes passes through the origin O (0,0)
