2x² + 6x - 3 + 2x³ - 3x + 2

Combine like terms

2x³ + 2x² + 6x - 3x - 3 + 2

Final answer:
2x³ + 2x² + 3x - 1

What is the simplified form of -24m^5 n^4/ 8m^-7 n^-2

solong [7]

Answer:

-3·m^12·n^6

Step-by-step explanation:

We assume you intend ...

(-24·m^5·n^4)/(8·m^-7·n^-2)

= (-24/8)·m^(5-(-7))·n^(4-(-2))

= -3·m^12·n^6

_____

If you really intend what you have written, then it simplifies to ...

(-24·m^5·n^4/8)·m^-7·n^-2 . . . . . note that all factors involving m and n are in the numerator

= (-24/8)·m^(5-7)·n^(4-2) = -3n^2/m^2

Well first of all, let's define what an integer is...

Integers are numbers such as -2, -1, 0, 1, 2 etc etc.

If f(5)=12,

f(6)=0.3*f(6-1)

= 0.3*f(5)

= 0.3*12

= 3/10 * 12

= 36/10

= 3.6

We now know that f(6)=3.6

Now:

f(7)=0.3*f(7-1)

= 0.3*f(6)

= 0.3*3.6

= (3/10) * (36/10)

= 108/100

= 1.08

Answer:

f(7)=1.08

Lines 3x-2y+7=0 and 6x+ay-18=0 is perpendicular. What is the value of a?

BlackZzzverrR [31]

Answer:

$\boxed{\sf a = 9 }$

Step-by-step explanation:

Two lines are given to us which are perpendicular to each other and we need to find out the value of a . The given equations are ,

$\sf\longrightarrow 3x - 2y +7=0$

$\sf\longrightarrow 6x +ay -18 = 0$

Step 1 : Convert the equations in slope intercept form of the line .

$\sf\longrightarrow y = \dfrac{3x}{2} +\dfrac{ 7 }{2}$

and ,

$\sf\longrightarrow y = -\dfrac{6x }{a}+\dfrac{18}{a}$

Step 2: Find the slope of the lines :-

Now we know that the product of slope of two perpendicular lines is -1. Therefore , from Slope Intercept Form of the line we can say that the slope of first line is ,

$\sf\longrightarrow Slope_1 = \dfrac{3}{2}$
