Answer:

4.5 and 1.5

Step-by-step explanation:

Let the 2 numbers be x and y with x > y , then

x + y = 6 → (1)

x - y = 3 → (2)

Add the 2 equations term by term to eliminate y, that is

2x + 0 = 9

2x = 9 ( divide both sides by 2 )

x = 4.5

Substitute x = 4.5 into (1) for value of y

4.5 + y = 6 ( subtract 4.5 from both sides )

y = 1.5

The 2 numbers are 4.5 and 1.5

What substitution Should be used to re-write 26(x^3+1)^2-22(x^3+1)-3=0 as a quadratic function?

mel-nik [20]

Answer:

$x^3+1$

Step-by-step explanation:

$26(x^3+1)^2-22(x^3+1)-3=0$

Comparing to

$A(u)^2+B(u)+C =0$

Where A,B,C are constants

You should see that we need to substitute the $x^3+1$ with u.

Find the common difference of the sequence shown 1/6,1/3,1/2,2/3,......

tekilochka [14]

Answer:

Common Difference(d) is

$d=\frac{1}{6}$

Step-by-step explanation:

Given sequence is :

$\frac{1}{6}, \frac{1}{3} ,\frac{1}{2} ,\frac{2}{3} .........$

If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.

Considering a sequence:

$a_1,a_2,a_3,a_4..........\\$

$a_2-a_1=a_3-a_2=a_4-a_3=a_n-a_n_-_1=d$

where 'd' is the common difference of the A.P.

Similarly, finding the common difference of the given sequence.

$\frac{1}{3} -\frac{1}{6}= \frac{1}{2}- \frac{1}{3}=\frac{2}{3} - \frac{1}{2}=d\\$

$d=\frac{1}{3}-\frac{1}{6}=\frac{(2)(1)-(1)(1)}{6}=\frac{1}{6}$

$d=\frac{1}{6}$

Common Difference(d) is

$d=\frac{1}{6}$

Everything bout this

Sometimes, but not always.
For example - If I vote for my candidate then he will win.
Reverse - If I don't vote for my candidate then he will not win.
The answer is false because an if then statement is a hypothesis not a fact.
