Pick a value for 'x' then solve for the 'y'
Ex: X=6 then 6-2y=2 then 4=2y then y=2y
So your answer will be 6,2.
Another answer to your question would be 4,1.
Plug them in... -4=x -5=y
-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)
-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)
Therefore the ordered pair IS NOT the solution.
Hope this helps :)
Distance between two points P(x1,y1), Q(x2,y2):
D=sqrt((x2-x1)^2+(y2-y1)^2)
Polygons are generally named in order along the perimeter, so that for a rectangle ABCD, AC or BD are diagonals.
Here, we need the distance between points A(4,3) and C(-4,-2)
Applying the above formula for distance between two points,
D=sqrt((4-(-4))^2+(3-(-2))^2)=sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89)
Correct option is B)
Cross-multiplication is helpful in Solving proportions.
<h3>What is Solving Proportions?</h3>
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying and solving the resulting equation.
<h3>What are the 2 methods for solving proportions?</h3>
Method I: Draw a double-sided number line, label the parts, set up a proportion and solve.
Method II: Using any method, calculate unit rate and then calculate how many pounds you can get for $30. Method III: Graph a point to represent the original ratio.
<h3>
What is the rule for solving proportions?</h3>
The product of the means is equal to the product of the extremes.
