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.
1.Consider the system of equations. x-5y=2
3x-10y=11
(a) Jamar rewrote the first equation as –2x + 10y = –4. What justification did he have for doing this?
(b)Jamar combined the equation in Part (a) with the second equation in the system to get x = 7. Explain Jamar’s reasoning.
(c) What is the solution of the system? (d) How do you know, without graphing, that the graph of 4x – 15y = 13 passes through the point whose coordinates are the solution of the system?

Answer:
127.3 ft
Step-by-step explanation:
A baseball diamond is constructed in a square shape.
The sides are 90 ft each
If a catcher throws a baseball to the shortstop who is half-way between second and third bases, the distance between the third base and the short stop = 1/2(90)
= 45 ft
length of the throw is found using Pythagoras theorem.
Hypothenus ^2 = opposite ^2 + adjacent ^2
= 90^2 + 45^2
Hypothenus = √8100 + 2025
=√10125
= 100.62 ft (approximately)
