The locomotive is 40 ft long.
40 ft = 40 * 12 in. = 480 in.
The locomotive is 480 inches line.
The model is 16 inches long.
480/16 = 30
The real locomotive is 30 times longer than the model.
A window on the locomotive is 30 times wider than a window on the model.

 If 2x3 – 4x2 + kx + 10 is divided by (x + 2), the remainder is 4. Find the value of k using remainder theorem. Please help :)​
Vinvika [58]

The polynomial remainder theorem states that the remainder of the division of a polynomial P(x) by x-a is equal to P(a).

Therefore

P(-2)=4\\2\cdot(-2)^3 - 4\cdot(-2)^2 + k\cdot(-2) + 10=4\\-16-16-2k=-6\\-2k=26\\k=-13

Solve by any method (graphing, substitution or linear combination)
Lostsunrise [7]

Answer:

b) (5, -3)

Step-by-step explanation:

The given equations are;

y=x-8...(1)

2x+3y=1...(2)

I prefer using substitution because of the first equation.

Put equation (1) into equation (2) to obtain;

2x+3(x-8)=1

We expand the parenthesis to obtain;

2x+3x-24=1

Group similar terms to get;

2x+3x=1+24

Simplify

5x=25

Divide through by 5;

x=\frac{25}{5}

\Rightarrow x=5

Put x=5 into equation (1) to get;

y=5-8

\Rightarrow y=-3

The solution is (5,-3).

The correct answer is B
