Answer:

Step-by-step explanation:

if the system of linear equation has no solution means that the lines do not intersect so they to not have any points in common ( there are no points that belong to both lines in the same time)

Think of equation as a rule and system of equation as two or more rules that have to be followed in the same time .

If you are asked to look in a parking lot full of cars and find what cars have

rule 1 -red color ( equation 1) and rule 2- is a truck ( equation 2) the cars you find are the solution of this system because the rules are true in the same time

Walmart sells to sizes of milk. One contains a half gallon of milk and costs $1.82.

aivan3 [116]

Answer:

Difference = $0.01

Step-by-step explanation:

Given that:

Cost of half gallon = $1.82

Cost of one gallon = $3.68

First we will convert gallons to ounces.

1 gallon = 128 ounces

half gallon = 64 ounces

Now,

we will find unit rate of both.

Unit rate of half gallon = $\frac{1.28}{64} = \$0.02$

Unit rate of one gallon = $\frac{3.68}{128} = \$0.03$

Difference= 0.03 - 0.02 = $0.01

Hence,

Difference = $0.01

What is the quadratic equation if the solutions are -9+ √65 /2, -9- √65 /2

liberstina [14]

Answer:

$4x^2+72x+259=0$

Step-by-step explanation:

If $x_1$ and $x_2$ are the solutions to the quadratic equation, then this equation can be written as

$(x-x_1)(x-x_2)=0$

In your case,

$x_1=-9+\dfrac{\sqrt{65}}{2}\\ \\x_1=-9-\dfrac{\sqrt{65}}{2}$

Then the equation is

$\left(x-\left(-9+\dfrac{\sqrt{65}}{2}\right)\right) \left(x-\left(-9-\dfrac{\sqrt{65}}{2}\right)\right)=0\\ \\\left(x+9-\dfrac{\sqrt{65}}{2}\right)\left(x+9+\dfrac{\sqrt{65}}{2}\right)=0\\ \\x^2+9x+\dfrac{\sqrt{65}}{2}x+9x+81+\dfrac{9\sqrt{65}}{2}-\dfrac{\sqrt{65}}{2}x-\dfrac{9\sqrt{65}}{2}-\dfrac{65}{4}=0\\ \\x^2+18x+\dfrac{259}{4}=0\\ \\4x^2+72x+259=0$
