Answer:

x=5,x=-5

Step-by-step explanation:

x^2-25=0

Add 25 to both sides:

x^2-25+25=0+25

x^2=25

Square root both sides:

x=\sqrt{25},\:x=-\sqrt{25} (Since a negative number multiplied by itself gives positive, there are two answers.)

x=5,x=-5

Hey there!

<h3>ANSWER: x=5\\x=25</h3><h2>EXPLANATION:</h2>

x^2-25=0

The first step we have to do is to add 25 to both sides of the equation.

x^2-25+25=0+25\\\text {equals }x^2=25

In our last and final step, we will have to take the square root.

x= ±\sqrt{25}

We have two answers.

x=5(ANSWER)\\x=-5(ANSWER)

Hope this helps!

Two airplanes are flying to the same airport. Their positions are shown in the graph. Write a system of linear equations that re
wariber [46]

Answer:

Airplane #1 equation: y=5/13x+42/13

Airplane #2 equation: y=1/3x+14

Step-by-step explanation:

So to find the slope of each airplane, you use the formula y2-y1/x2-x1. That means, for airplane#1 the equation will be 9-4/15-2. Simplify this and get 5/13. Then, for airplane#2, the equation will be 12-9/6-15. Simplify this and get 3/-9 and divide each side by 3 to get 1/-3 or -1/3. Next, use point slope formula to find the system of linear equations. Point slope formula is y-y1=m(x-x1). M is the slope. Use any point from the line. In this case, I will use (2,4). Tat means the first airplane's equation would be y-4=5/13(x-2). Then y-4=5/13x-10/13. Then, convert four into a fraction with a denominator of 13. This means, you have to multiply 4 by 13 to get 52/13. Add 52/13 to -10/13 to get 42/13. That means the first equation will be y=5/13x+42/13. The second equation point will be (6,12). This means the equation will be y-12=-1/3(x-6). Simplify this to get y-12=-1/3x+2. Simplify this to get y=1/3x+14. Therefore, Airplane#1 equation will be y=5/13x+42/13 and airplane #2 equation will be  y=1/3x+14.

Hope this helps
