The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

leva [86]
Hello There!

Area = l x w
14 = x * x - 5
Multiples of 14:
1 and 14
7 and 2
7 and 2 are the only ones with a difference of 5.

Therefore, the length is 7ft and the width is 2ft.

Hope This Helps You!
Good Luck :)

The graph represents the piecewise function
mr Goodwill [35]

The piece-wise function is defined as follows:

  • f(x) = x^2, 0 \leq x < 3.
  • f(x) = -\frac{5}{3}x + 14, 3 < x \leq 6.
  • f(x) = \frac{3}{2}x - 5, 6 \leq x \leq 10.

<h3>What is a piece-wise function?</h3>

A piece-wise function is a function that has multiple definitions, depending on the input.

In this graph, for x at least 0 and less than 3, the parabolic curve passes through (0,0), (1,1), (2,4) and has an open interval at (3,9), hence the definition is:

f(x) = x^2, 0 \leq x < 3

For x greater than 3 and at most 6, it is a line going through (3,9) and (6,4), hence:

m = \frac{9 - 4}{3 - 6} = -\frac{5}{3}

f(x) = -\frac{5}{3}x + b

Goes through (3,9), hence:

9 = -\frac{5}{3}(3) + b

b = 14.

So

f(x) = -\frac{5}{3}x + 14, 3 < x \leq 6

For x between 6 and 10, it is a line going through (6,4) and (10,10), hence:

m = \frac{10 - 4}{10 - 6} = \frac{6}{4} = \frac{3}{2}

Then:

f(x) = \frac{3}{2}x + b

When x = 10, f(x) = 10, hence:

10 = \frac{3}{2}(10) + b

10 = 15 + b

b = -5.

Hence:

f(x) = \frac{3}{2}x - 5, 6 \leq x \leq 10
