Slope is 4/12=1/3

y-10=1/3(x-9)
y-10=1/3x + -3
y = 1/3x + 7

Answer:

The expression is 4b^{6}c^{3} ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- In the exponent rules, we add the exponents when we multiply terms

 have same base

- Ex: a^{m}*a^{n}=a^{m+n}

- The volume of the rectangular box is the product of its three

 dimensions

* Lets solve the problem

- John buys a water tank from a company

- The  tank he buys has the dimensions b² by b^4 by 4c³

∵ The water tank is shaped a rectangular box

∵ The tank has dimensions b^{2},b^{4},4c^{3}

∵ The volume of the tank = L × W × H , where L , W , H are the

  dimensions of the tank

- Assume that L = b² , W = b^{4} and H = 4c³

∴ The volume of the tank = b² × b^{4} × 4c³

- b² and b^4 has the same base, then add its exponents

∴ The volume of the tank = b^{4+2} × 4c³

∴ The volume of the tank = b^{6} × 4c³

∴ The volume of the tank = 4b^{6}c^{3}

* The expression which represents the volume of the tank is:

  4b^{6}c^{3}

∴ The answer is the second expression

Subtract 9x^2 – 10x + 1 from -2x^2 + 4x – 10.
OleMash [197]

Answer:

11x^2  −6x−9

Step-by-step explanation:

9x^2 – 10x + 1 - ( -2x^2) + 4x – 10.

The opposite of −2x^2 is 2x^2

9x^2 −10x+1+2x ^2 +4x−10

Combine 9x^2  and 2x^2  to get 11x^2 .

11x^2 −10x+1+4x−10

Combine −10x and 4x to get −6x.

11x^2 −6x+1−10

Subtract 10 from 1 to get −9.

11x^2  −6x−9
