Calculus

190 grams = 0.42 pounds

y=-2/3x

Because of the zero property of multiplication we must first set it equal to zero and factor the equation.

z^2+8z=-15

z^2+8z+15=0

(z+3)(z+5)=0 either z+3=0 or z+5=0

So, z=-3 or z=-5

The way I factored it is looked for two numbers that multiplied to give me 15 but added to make 8. 1 and 15 didn't work. 3 and 5 worked.

they are just variables, they are put in place of a number that you need to find out ;) your welcome hot stuff

According to my interpretation, you have :

P(t) = ( 222 )( 1.056 )^t

For 2013, you would have :

P(13) = ( 222 ) ( 1.056 )^13

P(13) = ( 222 ) ( 2.0306 )

P(13) = 446.739 thousand = 446,739 <-----------------

Answer: 446.739 thousand in 2013 <-------------------

546.

4+3=5+2

or

4+5=32

17x = 17 + x

Subtract x from both sides.

16x = 17

Divide each side by 16.

x = 17/16 or 1 and 1/16 or 1.0625

Check it.

17 x 1.0625 = 18.0625

17 + 1.0625 = 18.0625

It checks.

Put it into slope intercept form and then proceed to use your favorite method of graphing.

slope-intercept:

y = -3x + 1

y = x/4 - 1

2a2 x 3a-3 = (2 x 3)a(2 + -3)

= 6a-1

2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0

So (x - 2)*(2x - 5) = 0

If: x+10 = 25

Then: x = 15

130.

The idea is to replace "x" by its value, to replace "y" by its value, and then to do the calculations.

hi there i have a sym jet 50 and i want to know the best way to deristrict it or to make it go faster does anyone have any surgestions?

5x2 - 3x - 7 = 0 where a = 5, b = -3, and c = -7

x = [-b ± √b2 - 4(a)(c)]/2a

x = [-(-3) ± √(-3)2 - 4(5)(-7)]/2(5)

x = [3 ± √(9 + 140)]/10

x = (3 ± √149)/10

x = (3 ± 12.21)/10

x = (3 + 12.21)/10 = 15.21/10 = 1.521 or

x = (3 - 12.21)/10 = -9.21/10 = -0.921

The EXACT answer would be x = 3/10 ± √149 /10

Note: 149 is not divisable by a perfect square
