Answer:
2a
Step-by-step explanation:
using distance formula:
√(x₂-x₁)² + (y₂-y₁)²
putting values,
√{a-(a)}² + {b-b}² = √ {a+a}² + 0²
= √(2a)² = √4a² = 2a
Hope this helps:)
First, distribute the 100 to the (x-1) portion:
500 = 100x - 100
then, add 100 to both sides of your equation to get “x” alone on the right side:
500 + 100 = 100x - 100 + 100
600 = 100x
next, divide 100x by 100 and 600 by 100 to isolate a singular “x”:
600/100 = 100x/100
6 = x
therefore, x=6 is your solution
452.16 m^3
1/3 = 0.333333333
0.333333333 * 3.14 = 1.046666667
1.046666667 * 144 =150.72
150.72 * 3 = 452.16
On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The linear equation is shown below.

The equation can be written as

For y = 15, the value of x will be.

The value of x is 200.
Thus, option D is correct.
