It takes 0.5 hour for the water to decrease by one liter. You can also tell because the line is going down showing that it is decreasing or you can subtract the X-axis

2 - 1.5 which equals 0.5.

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)

lozanna [386]

Answer: x=4

Step-by-step explanation:

1.5(x+4)-3=(x-2)

1.5x+6)-3=4.5x-9

1.5x+3=4.5x-9

+9 +9

1.5x+12=4.5x

divide 1.5x and 4.5

12=3x

Describe the nature of the roots for this equation

vitfil [10]

First, fint the roots of the equation $2x^2+5x-7=0.$

$D=5^2-4\cdot 2\cdot (-7)=25+56=81,\\\sqrt{D}=\sqrt{81}=9,\\ \\x_1=\dfrac{-5-9}{2\cdot 2}=-\dfrac{14}{4}=-3.5,\\ \\x_2=\dfrac{-5+9}{2\cdot 2}=\dfrac{4}{4}=1.$

2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.
