The first one, or y = -2x+3. Next time you find things like this, you can go to desmos.com, and click start graphing. You can try all the different equations, and see which one is right. Hope this helps!

The equation is y= -2x + 3.

The 3 is the y-intercept and how I got -2 was that I did rise/run. It went down 2 times and over once so -2/1, which will give you simply -2.

what are the solution(s) to the quadratic equation x2 – 25 = 0? x = 5 and x = –5 x = 25 and x = –25 x = 125 and x = –125 no real
sattari [20]
The left hand side expression of the given equation is a difference of two squares. The first term, x², is a square of x and the second term, 25 is the square of 5. The factors of the expression are (x - 5) and (x + 5).
                                   (x - 5)(x + 5) = 0
The values of x from the equation above are x = -5 and x = 5.

Mr. Ignacio went diving along the coral reef in Oahu. He descended 12 meters below the sea. The difference between this point on
Aliun [14]

Answer:

488 meters above sea level.

Step-by-step explanation:

Since the difference between that point and the tallest point is 1,232 you need to subtract 1,232 - 12 = 1,220 to get how far Mt ka'ala is from sea level. Since the ranger station is 2/5 up the mountain you can do 1,220/5 = 244. This is 1/5 of the way up the mountain. Then you do 244 x 2 = 488. That is 2/5 up the mountain. Final answer: The ranger station is 488 meters above sea level.
