2x - y = -10
y = 4x
2x - 4x = -10
-2x = -10
x = 5
y = 4x
y = 4* 5
y = 20
Answer : (x,y) = (5,20)
I tried graphing the points, and I formed a right triangle.
short leg = 6-1 = 5
Hypotenuse = 13
long leg = ?
a² + b² = c²
a² + 5² = 13²
a² = 13² - 5²
a² = 169 - 25
a² = 144
√a² = √144
a = 12
S has coordinates (6,y) = y = 12 + 3 = 15
S (6,15)
We have an angle and an adjacent side, and we are looking for an opposite side. Because we have adjacent and opposite, that tells us that we need to use tangent.
10 * tan(31) = 6.008, when rounded to the nearest tenth you would just say 6.
169 is a perfect square which equals 13
21/25 is already a fraction and if you wanted it to be simplified, its already simplified to be 21/25.
