What is 3/4 of 3/9?

Artyom0805 [142]

3/4 = .75 so you have to find 75 % of 3/9
100% = 3/9
1% = (3/9)/100
75% = (3/9)/100 * 75 =.25

Explain why the expression 9x^3+1/2x^2+3x^-1 is not a polynomial

Nastasia [14]

Answer:

The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.

Step-by-step explanation:

P(x,n) is a polynomial of nth degree if it is of the form,

P(x,n) = $a_{0} + a_{1}x + a_{2}x^{2} + a_{3}x^{3} + ......... +a_{n}x^{n}$

where n is a finite positive integer and n ∈ N

and ' $a_{i}$ 's are fixed but otherwise arbitrary constants ∀ i = 0(1)n .

Now, the given expression is,

$9x^{3} + \frac {1}{2x^{2}} + 3x^{-1}$

which doesn't fit in the above form. Hence, it is not a polynomial.

Write the doubles plus one fact for 7+7.

Pie

Answer:

7 + 8 = 7 + 7 + 1.

Step-by-step explanation:

We know that, 'double plus one facts' is used to make the addition of numbers easy.

For e.g. we have 8 + 9 = 17. This addition can also be done as 8 + 8 + 1 = 17 i.e. we write first term twice and add 1 to get the result.

Hence, we give the name to this type of addition as 'double plus one'.

Now, we have to use this fact for 7 + 7.

So, we consider 7 + 8 = 15.

Therefore, 7 + 8 can be written as 7 + 7 + 1

Hence, the double plus one facts for 7 + 7 is 7 + 8 = 7 + 7 + 1.

Required equation in slope intercept form is: $y=5x+4$

Step-by-step explanation:

Given

Let m denote the slope of line

m = 5

the line passes though (1,9)

Slope-intercept form of equation of line is:

$y= mx+b$

Putting m=5 in the equation

$y = 5x+b$

Putting (1,9) in the equation

$9 = 5(1) +b\\9 = 5+b\\b = 9-5\\b = 4$

Putting the value of b

$y = 5x+4$

Hence,

Required equation in slope intercept form is: $y=5x+4$
