Arturiano [62]

Answer:

The answer is Graph X.

Always start by isolating the variable \color{red}y on the left side of the inequality.
Change the inequality to equality symbol.
Graph the boundary line from step 2 in the XY-plane.
The last step is to shade one side or region of the boundary line.

If the product of two number is 10 and the sum is 7 ,then the longest of the two number is

irinina [24]

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

$10/y+y= 7\\\\10/y= 7-y$

cross multiply we have

$10=y(7-y)\\\\10=7y-y^2$

rearrange

$y^2-7y+10=0$

the factors of the quadratic expression are

-5 and -2

$y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\$

The longest side is 5 units
