Answer:

(x, y) = (0, -2248)

Step-by-step explanation:

Substitution

Substitute for y:

300x -2248 = 350x -2248

0 = 50x . . . . . . . . add 2248-300x to both sides

x = 0

y = 300·0 -2248

The solution is (x, y) = (0, -2248).

Elimination

Subtract the first equation from the second.

(y) -(y) = (350x -2248) -(300x -2248)

0 = 50x

x = 0

y = 300·0 -2248

The solution is (x, y) = (0, -2248).

Additional comment

If you think for a bit about what the graph looks like, you realize both lines cross at their y-intercept, (0, -2248). That point of intersection is the solution to the system of equations.

Answer:

1) Bigger sector = 168.8pi

1) Smaller sector = 56.3pi

2) Bigger sector = 529.9

3) Smaller sector = 176.6

Step-by-step explanation:

1) Bigger sector = $\frac{270}{360}$ ×pi×15×15

= 168.75pi

1) Smaller sector = $\frac{360-270}{360}$ ×pi×15×15

= $\frac{90}{360}$ ×pi×15×15

= 56.25pi

2) Bigger sector = $\frac{270}{360}$ ×3.14×15×15

= 529.875

2) Smaller sector = $\frac{360-270}{360}$ ×3.14×15×15

= $\frac{90}{360}$ ×3.14×15×15

= 176.625

Answer:

Tim will get £ 8

Sam will get £ 32

Solution,

let the ratios be x and 4x

 $x + 4x = 40 \\ or \: 5x = 40 \\ or \: x = \frac{40}{5} \\ x = 8 \\ replacing \: value \\ 4x \\ = 4 \times x \\ = 4 \times 8 \\ = 32$ 

hope this helps...

Good luck on your assignment...
