Answer:

Option D is correct

\sqrt{(5-9)^2+(1+6)^2}

Step-by-step explanation:

Formula for Distance(D) between two points is given by:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

As per the statement:

Given the points (5, 1) and (9,-6)

Apply the distance formula we have;

⇒D=\sqrt{(5-9)^2+(1-(-6))^2}

⇒D=\sqrt{(5-9)^2+(1+6)^2}

Therefore, the expression gives the distance between the points (5, 1) and (9,-6) is, \sqrt{(5-9)^2+(1+6)^2}

2. What is the x-value to the solution for the system of equations y = -5x - 9 and y = 2x<br> + 5.
pav-90 [236]

Answer:

The x-value is -2

Step-by-step explanation:

U can substitute any of the equations for y

-5x + (-9) = 2x + 5

-9 = 7x + 5

-14 = 7x

-2 = x

x = 2

Solve each equation. Record your work and check your solution. <br> a. 5(x-2)+(-9)= -7(1-x)
Daniel [21]

The solution for equation is x = -6

<em><u>Solution:</u></em>

<em><u>Given equation is:</u></em>

5(x-2) + (-9) = -7(1-x)

We have to solve the equation

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

Therefore, solve for brackets in given equation

5(x-2) + (-9) = -7(1-x)\\\\5x - 10 -9 = -7 + 7x

Solve for terms in left hand side of equation

5x - 19 = -7+7x

Move the variables to one side and constants to other side

7x -5x = -19+7\\\\2x = -12\\\\Divide\ both\ sides\ by\ 2\\\\x = -6

Thus the solution for equation is x = -6
