5b-4-8b-9

You can only combine like terms and the negative sign belongs to the term after it.
so put a circle around 5b
and a circle around -8b
5bricks - 8 bricks =? (it will be a negative number of bricks)

now just tack the answer to -4-9 on the end.

s the sequence 1/2, 1/3, 1/6, 0 arithmetic?

It is an AP if
T2-T1 = T3-T2 = T4-T3 (=d)

So you work it out!

If theta is a fourth-quadrant angle such that sec theta= 4, use a trigonometric identity to find the exact value of tan theta. Decimal answers are not allowed. Use simplified radical form, if necessary.

I don't know about trig identities, I'd just do it with a triangle.
Draw a right angled triangle
label one of the acute angles theta,
Put 4 on the hypotenuse and 1 on the adjacent side. Now you have sec theta = 4
use pythagoras to get the other side as square root 15.
tan theta = opp/adj=root15/1 but it is in the 4th quad so it is negative
tan theta = -root15

cubed root of [(x^3+3x^2-8)-x-1]=0
A cubed root is a power of 1/3

[(x^3+3x^2-8)-x-1] ^1/3 = 0

Raise both sides to the power of 3

{[(x^3+3x^2-8)-x-1] ^1/3} ³ = 0 ³

(x^3+3x^2-8)-x-1= 0

x^3+3x^2-8-x-1= 0

x^3+3x^2-x-9= 0

I can't do this, I think one of the digits is wrong. Are you sure you copied the question correctly?

Now it is your turn Rosey,

John saved for a car.
He bought a car and borrowed 72% of its total value from a bank.
He borrowed $3600
He used all of his own savings for the balance. (The rest of the cost)
How much had he saved?
----------------------------------------
Ahora es tu turno Rosey,

John guardado para un coche.
Compró un auto y pidió prestado el 72% de su valor total de un banco.
Pidió un préstamo de $3600
Él utilizó todos sus ahorros para el equilibrio. (El resto del coste)
¿Cuánto había salvado?

Hi Rosey,

It is nice to hear from you again!

I think you mean something like this.
The CEO of a company owns 1800 shares and this is 60% of the whole company.
He wants to buy the rest of the shares. How many shares does he want to buy?

Well he wants to buy 40% but how much is that?
If 60% is 1800shares
then
60/60% must be 1800/60 shares (I divided them both by 60 to find 1% )
1% must be 1800/60 shares
1*40% must be 1800/60 *40 shares
40% must be 1200 shares.
---------------------------------------------------
Hola Rosey,

Es lindo volver a oír de usted!

Creo que te refieres a algo como esto.
El CEO de una empresa posee acciones de 1800 y éste es el 60% de toda la empresa.
Quiere comprar el resto de las acciones. ¿Cuántas acciones quiere comprar?

Bueno que quiere comprar el 40%, pero ¿cuánto es?
Si el 60% es 1800shares
Entonces
60/60% deben ser acciones de 1800/60 (Dividí las dos por 60 a encontrar 1%)
1% debe ser 1800/60 acciones
1 * 40% deben ser 1800/60 * 40 acciones
40% debe ser 1200 acciones.

I think it means for every dollar (266) take away 80 cents which would be 266 x 0.80 = Y (So you can figure it out on your own.) then 266.42 - Y = your answer

To find the x- and y-intercepts of -3x-4y=18:
Two Separate problems to solve!!
1st To find the x-intercept:
Let y=0 and solve for x.
-3x-4*0=18
-3x=18
x=18/-3
x=-6 --> x-intercept is (-6,0)
2nd To find the y-intercept:
Let x=0 and solve for y.
-3*0-4y=18

-4y=18
y=18/-4
y=-9/2
y=-4.5 --> y-intercept is (0, -4.5)
To graph, plot the x- and y-intercepts and draw the line!!
You should also choose an x- or y-value, substitute into the original to find a check point. If your x- and y-intercepts are correct, the point will lie on the line.
Example: If we let x=1, then
-3*1-4y=18
-3-4y=18
-4y=21
y=21/-4
y=-5 1/4
y=-5.25 --> (1, -5.25) should lie on the line drawn using the intercepts

Espero que ayuda <3

Depends if you are sharing the dollar between three people. you, and your two friends which would be 98 cents for you and 2 pennies for them but if it is you and other friend counting as two people, then 50 cents each

Hi mimi,
I assume you mean Given f(x) = x + 2 and g(x) = x ², what is the value of f(g(x))

It is just f(g(x)) = x ² +2

You simply replace the x in the f(x) function with the value of g(x).

18/25 x 3/4=
numerator times numerator divided by denominators multiplied...
18*3 / 25*4 =
18*3 / 100 =
54 / 100 =
= 0.54
or in fraction form:
= 27/50

GuestNov 5, 2013

Multiply both numerators and denominators with one another:
18 x 3 = 54
25 x 4 = 100

New fraction = 54/100

which reduces to: 27/50
