Answer:

19.41 units

Step-by-step explanation:

<u>Given coordinates of points;</u>

(-10, 9)
(-6, -10)

To determine the distance between the two points, the distance formula is required. The distance formula is used where it is not possible to calculate the distance through a straight line. The distance formula is expressed as,

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

The distance between the two points can be determined by plugging the coordinates into the formula;

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$
⇒ $\sqrt{[-6 - (-10)]^{2} + [-10 - 9]^{2} }$

Then, we can simplify the root as needed to determine the distance;

⇒ $\sqrt{[-6 + 10]^{2} + [-19]^{2} }$
⇒ $\sqrt{[4]^{2} +361 }$
⇒ $\sqrt{16 +361 }$
⇒ $\sqrt{377}$

Finally, we need to convert the root into decimals (stated in question). It is impossible to determine the root in decimal form. Therefore, I used a calculator to determine the distance in decimal form.

⇒ $\sqrt{377}$ ≈ 19.41 units [Using calculator]

Therefore, the distance between the two points is about 19.41 units.

Y^2 − 20x − 6y − 51 = 0

grin007 [14]

answer:

Simplifying Y2 + -20X + -6y + -51 = 0

Reorder the terms: -51 + -20X + Y2 + -6y = 0

Solving -51 + -20X + Y2 + -6y = 0

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '51' to each side of the equation. -51 + -20X + Y2 + 51 + -6y = 0 + 51

Reorder the terms: -51 + 51 + -20X + Y2 + -6y = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -20X + Y2 + -6y = 0 + 51 -20X + Y2 + -6y = 0 + 51

Combine like terms: 0 + 51 = 51 -20X + Y2 + -6y = 51

Add '-1Y2' to each side of the equation. -20X + Y2 + -1Y2 + -6y = 51 + -1Y2

Combine like terms: Y2 + -1Y2 = 0 -20X + 0 + -6y = 51 + -1Y2 -20X + -6y = 51 + -1Y2 Add '6y' to each side of the equation. -20X + -6y + 6y = 51 + -1Y2 + 6y Combine like terms: -6y + 6y = 0 -20X + 0 = 51 + -1Y2 + 6y -20X = 51 + -1Y2 + 6y Divide each side by '-20'. X = -2.55 + 0.05Y2 + -0.3y Simplifying X = -2.55 + 0.05Y2 + -0.3y
