Which list of ordered pairs represents solutions to x + y = 2? (-4, 6), (0, 2), (4, 2); (-4, -6), (0, 2), (4, 2); (-4, 6), (0, 2

baherus [9]

Answer:

(-4, 6), (0, 2), (4, -2)

Step-by-step explanation:

x + y = 2?

(-4, 6), -4+6 = 2 True this is a solution

(0, 2), 0+2 = 2 True this is a solution

(4, 2); 4+2 = 6 False this is not a solution

This is not a solution set since we have a pair that is not a solution

(-4, -6), -4+-6 = 10 False this is not a solution. We do not have to check the rest since this cannot be a solution set

(0, 2),

(4, 2);

This is not a solution set since we have a pair that is not a solution

(-4, 6), -4 + 6 = 2 True this is a solution

(0, 2), 0 + 2 =2 True this is a solution

(4, -2) 4-2 =2 True this is a solution

This is a solution set since all the points are a solution

Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number

Tanzania [10]

Given:

The equation is

$\begin{gathered} 6x+4y=16 \\ \\ 9x+6y=24 \end{gathered}$

Find-:

The solution of the equation

Explanation-:

The first equation is

$\begin{gathered} 6x+4y=16 \\ \\ 2(3x+2y)=16 \\ \\ 3x+2y=\frac{16}{2} \\ \\ 3x+2y=8 \end{gathered}$

The second equation is

$\begin{gathered} 9x+6y=24 \\ \\ 3(3x+2y)=24 \\ \\ 3x+2y=\frac{24}{3} \\ \\ 3x+2y=8 \\ \end{gathered}$

Both equations are the same.

For slove, the two unknown variables need two equations.

So,

There is NO SOLUTION

A circle with area 9pi has a sector with a central angle of 60 degrees What is the area of the sector ?

belka [17]

Area of the sector is 4.71 sq units

Step-by-step explanation:

Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.

Area of the sector = πr²(C/360) = 9π × 60/360

= 9 × 3.14 × 1/6

= 28.26/6 = 4.71 sq units
