x2+7x-8 = (x-1(x+8)

If you're asking for the graph, then the function y=x would look like a diagonal line going towards the upper-right hand corner of the coordinate plane.

18x2 + 2
= 2(9x2 + 1)
= 2(9x2 - -1)
= 2[(3x)2 - i2]
= 2(3x + √-1)(3x - √-1) (substitute i for √-1)
= 2(3x + i)(3x - i)

x= 7

You have x-3= 4

Add 3 to both sides to cancel out the -3

This leaves you with x=7

The value of x can be determined by subtracting 6 from 9.

4xy - 2xy

my head hurts now u bich

Just double the 2 X 10 to find 4 X 10.

Taking the derivative:

2lnx+2, 2(lnx+1).

Extrema occur at y'=0.

2(lnx+1)=0,lnx=-1

x=e^(-1)=1/e

y=-2/e

So the extrema occurs at (1/e,-2/e)

Z = K Y / X

'K' can be any constant number.

32 x 82 = 2624

12, 2, 11, 4, and 1

1 liter = 1000 ml

1000 liters = 1 Kilolitre

1 Kiloliters = 1000 litres = 1000 x 1000 ml = 2000 ml

Thus, 1 Kl is 1 million (1000000) milliliters.

There is no scientific name for the width of the index finger. The name index finger literally means pointing finger.

8x + 64y = 176

Add: 62y = 186 so y = 3 and x = -2

This assumes you mean "equals 10", not "plus 10"

(-5, 2)

In a sence it does; it means 3 units up on the y-axis, which is the point at which it crosses the y-axis.

7.75 or 7 and 3/4

sinx

If you mean: y =(lnx)3

then:

dy/dx = [3(lnx)2]/x

ddy/dx = [(6lnx / x) - 3(lnx)2] / x2

If you mean: y = ln(x3)

Then:

dy/dx = 3x2/x3 = 3/x = 3x-1

ddy/dx = -3x-2 = -3/x2

x = 104

Because we muliply the three sides of a cube of one meter length x 3. =1000x1000x1000=1,000,000
