Answer:

  B)  -125

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic.

  (a^2 -b^2)^3

  = (2^2 -(-3)^2)^3

  = (4 -9)^3

  = (-5)^3

  = -125 . . . . . matches choice B

Find the y intercept and slope
Naya [18.7K]
Okay so first off the equation of a line is
Y=mx+b
m= the slope
b= the y intercept

The Y intercept of this line is 2 and the slope is 5/3! You know this is the slope because if you start at point a and go up 5 and to the right 3, you end up at point b.

The equation for this line would be y=5/3x+2

Jenny bought a 5 notebooks and 2 pencils, and the total was 9 dollars.
weeeeeb [17]
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5

Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75

So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!

Step-by-step explanation:

STEP 1:

8^{2}v^{2*2} - 15^{2}w^{2*5}

STEP 2:

8^{2} * (v^{2})^{2} - 15^{2} * (w^{5})^{2}

STEP 3:

(8v^2)^2 - (15w^5)^2

STEP 4:

(8v^2-15w^5)(8v^2+15w^5)
