What is the difference of two positive rational number always positive?

1 answer:

Alexeev081 [22]3 years ago

6 0

No, while the difference represents the absolute magnitude of two numbers . . . for example . . .

The difference between 5 and 2 is . . . 3
The difference between 6.4 and 9.5 is . . . 3.1

. . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative

. . . so in short . . . the answer is . . . <span>NO</span>

Which two equations would be most appropriately solved by using the quadratic formula?

leva [86]

For this case we have that by definition, the quadratic formula is: $x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

A quadratic equation is of the form:

$ax ^ 2 + bx + c = 0$

Option A: This equation can be solved without the quadratic formula

$x ^ 2 = \frac {9} {3}\\x ^ 2 = 3\\x = \pm \sqrt {3}$

Option B:

This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.

Option C:

$-2x ^ 2 + 5x = 7$

Similarly, this equation can be solved with the quadratic formula

Option D:

$- (x - 3) (x + 9) = 0$

In this factored equation we can see that the roots are

$x_ {1} = 3\\x_ {2} = - 9$

Answer:

Option B, C

A tree grow 1/4 foot in 1/12 year.

lilavasa [31]

Answer:

Part A) The rate is $\frac{12}{4}\ \frac{feet}{years}$

Part B) In 1 year the tree grows 3 feet

Step-by-step explanation:

Part A) write the rate at which this tree grows as a fractions

we know that

To find out the rate at which the tree grows divide 1/4 foot by 1/12 year

so

$\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}$

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of $\frac{12}{4}\ \frac{feet}{years}$

Simplify

$\frac{3}{1}\ \frac{feet}{year}$

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet

What’s the answer to this question below. A b c or d

maks197457 [2]

Answer:

$a=0$

Step-by-step explanation:

The given expression is;

$(\frac{1}{7})^{3a+3} =343^{a-1}$

This implies that;

$7^{-1(3a+3)} =7^{3(a-1)}$

Equate the exponents;

$-1(3a+3) =3(a-1)$

Expand;

$-3a-3 =3a-3$

$-3a-3a =-3+3$

$-6a=0$

$a=0$
