tangare [24]

Answer:

Step-by-step explanation:

4 quarts=1 gallon

1 quart=1/4 gallon

6 quarts 1/4×6=6/4 gallons=3/2 gallons =1  1/2 gallons

or we can say 4 quarts=1 gallon

2 quarts=1/2 gallon

(4+2=6)quarts=(1+1/2)=1 1/2 gallon.

The distance (d) in meters that an ant can travel varies directly with the amount of time (t) in hours it spends walking.assume
Assoli18 [71]

Answer:  d=18t

Step-by-step explanation:

By definition, Direct proportion equations have the following form:

y=kx

Where "k" is the constant of proportionality.

In this case you know that the distance (in meters) that an ant can travel varies directly with the amount of time (in hours) the ant spends walking.

With this information you can write the following equation:

d=kt

According to the exercise, the constant of proportionality is:

k=18

Therefore, substituting the value of the constant of proportionality into the equation, you get that  the equation that represents the proportional relationship between "d" and "t" is:

d=18t

<u>Question:</u>

Find the number of real number solutions for the equation. x^2 + 5x + 7 = 0

<u>Answer:</u>

The number of real solutions for the equation x^{2}+5 x+7=0 is zero

<u>Solution:</u>

For a Quadratic Equation of form : a x^{2}+b x+c=0  ---- eqn 1

The solution is x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}  

Now , the given Quadratic Equation is x^{2}+5 x+7=0  ---- eqn 2

On comparing Equation (1) and Equation(2), we get

a = 1 , b = 5 and c = 7

In x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} , b^2 - 4ac is called the discriminant of the quadratic equation

Its value determines the nature of roots

Now, here are the rules with discriminants:

1) D > 0; there are 2 real solutions in the equation

2) D = 0; there is 1 real solution in the equation

3) D < 0; there are no real solutions in the equation

Now let solve for given equation

D= b^2 - 4ac\\\\D = 5^2 - 4(1)(7)\\\\D = 25 - 28 \\\\D = -3

Since -3 is less than 0, this means that there are 0 real solutions in this equation.
