Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4
I can help you understand this, however there is nothing but 'M'
Answer:
XY = 4
Step-by-step explanation:
Side XY corresponds to side PQ and is congruent to side XY.
The distance from P to Q is 4 since those two points are 4 units apart on the x-axis.
Answer: XY = 4
The length of the third side of the tringle must lie in between 7 and 7 i.e length of the third side will always be greater than 7 and smaller than 17 according to the properties of a triangle.
According to the given question.
We have a right angled triangle with the two side lengths 5 unit and 12 unit.
From the properties of a triangle we know that " the sum of the length of the two sides of a triangle is greater than the length of the third side". Or " the difference between the two sides of a triangle is less than the length of the third side".
Let the third side of the triangle be x units.
So, by the properties of a triangle we can say that
12 - 5 < x
⇒ 7 < x
And 12 + 5 > x
⇒ 17 > x
Therefore, the length of the third side of the tringle must lie in between 7 and 7 i.e length of the third side will always be greater than 7 and smaller than 17.
