The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?Shown working out pl

8_murik_8 [283]

Let numbers be x and y

ATQ

x+y=49---(1)

x-y=9---(2)

Adding both

$\\ \sf\longmapsto 2x=58$

$\\ \sf\longmapsto x=\dfrac{58}{2}$

$\\ \sf\longmapsto x=29$

Now putting value in eq(2)

$\\ \sf\longmapsto x-y=9$

$\\ \sf\longmapsto 29-9=y$

$\\ \sf\longmapsto y=20$

If only two points are needed to determine a line why are three ordered pair solutions or points found for a linear equation

makvit [3.9K]

Two points give you a line. A third point (often called a check-point) is used to confirm the accuracy of your first two points. If all three line up, you have confirmed you have the correct line.

If EF bisects CD, CG =5x-1, GD = 7x-13, EF = 6x-4, and GF =13, find EG

VARVARA [1.3K]

<em>Greetings from Brasil....</em>

As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD

5X - 1 = 7X - 13

X = 6

EF = EG + GF

6X - 4 = EG + 13 x = 6, so

6·6 - 4 = EG + 13

<h2>EG = 19</h2>
