20 x^3-10 x^2+0, when x=4

=1,120

Solve the following system:
{y = x+9
3 x+8 y = -5

Substitute y = x+9 into the second equation:
{y = x+9
3 x+8 (x+9) = -5

3 x+8 (x+9) = (8 x+72)+3 x = 11 x+72:
{y = x+9
11 x+72 = -5

In the second equation, look to solve for x:
{y = x+9
11 x+72 = -5

Subtract 72 from both sides:
{y = x+9
11 x = -77

Divide both sides by 11:
{y = x+9
x = -7

Substitute x = -7 into the first equation:
{y = 2
x = -7

Answer: |x = -7                 and                   y = 2

5.6 =5 6/10 =5 3/5

2/3 (fraction) x + 4 = 3/5 (Fraction) x - 2

(3.54 x 10²¹) / (3 x 10¹⁴)  =  (3.54 / 3) x (10²¹ / 10¹⁴)

Divide 3.54 by 3  =  1.18.

Simplify 10²¹ / 10¹⁴ (by subtracting exponents) = 10⁷.

Therefore, the answer is  1.18 x 10⁷.

Just use the calculator. If you have problems, then ask for help.

Each ticket costs $45.50 ($37.00 + $8.50).

You paid a total of $242.49, which includes a transaction fee of $14.99.

Subtracting $14.99 from $242.49, gives a value of $227.50, which is the cost of the tickets.

To find how many tickets were bought, divide $227.50 by $45.50.

$227.50 / $45.50  =  5, the number of tickets bought.

online concert tickets cost $37 each, plus a service charge of $8.50 per ticket. The website also charges a transaction fee of $14.99 for the purchase. You paid $242.49. How many tickets did you buy?

242.49 - 14.99 =$227.50 money spent on purchase of tickets only.

$227.50 / [$37 + $8.50]=

$227.50 / $45.50 =5 tickets were purchased.

Just subtract: 5/6 - 3/8 =11/24 that is how much you drank.

If your answer were: x^2 - 100, it would be "D". But, x^2 + 100, none of them!!.

Yeah, the only REMOTELY close one is D.

No you aren't. Now stop disrupting this math board and do something better with your life. Goodbye, sir.

That's what I'm thinking now but the teacher specifically said "If you don't do all the problems, it is a 0." But this one is unsolvable, so what am I going to do? Hope he understands or make up some work and say I didn't understand it just to be safe?

This is how I do it: Enter 64 first, then press "x^y" key, then open bracket (, then enter 1 / 12), followed by = key to get the answer. There maybe shorter ways of doing it, but I don't use it that much.

It can't be any of these. 

Thank you,

Expand the following:
4 x^2 y^3 (3 x-7 y)

4 x^2 y^3 (3 x-7 y) = 4 x^2 y^3×3 x+4 x^2 y^3 (-7 y):
4×3 x^2 y^3 x-7×4 x^2 y^3 y

4 x^2 y^3×3 x = 4 x^(2+1) y^3×3:
4×3 x^(2+1) y^3-7×4 x^2 y^3 y

2+1 = 3:
4×3 x^3 y^3-7×4 x^2 y^3 y

4×3 = 12:
12 x^3 y^3-7×4 x^2 y^3 y

4 x^2 y^3 (-7) y = 4 x^2 y^(3+1) (-7):
12 x^3 y^3+-7×4 x^2 y^(3+1)

3+1 = 4:
12 x^3 y^3-7×4 x^2 y^4

4 (-7) = -28:
Answer: |12x^3y^3 - 28x^2y^4
