What is the value of x in the diagram?
cestrela7 [59]

Answer:

x = 5

Step-by-step explanation:

x² + (2x+2)² = (2x+3)²

x² + 4x² + 8x + 4 = 4x² + 12x + 9

x² - 4x - 5 = 0

(x - 5)(x + 1) = 0

x = -1  This can be discounted as the answer because you cannot have a negative length

answer: x = 5

Answer:

1.) slope=2

2.) slope=-3

3.) slope=\frac{1}{4}

4.) slope=-\frac{4}{5}

Step-by-step explanation:

The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope

However, with certain graphs, the slope can be found in a simpler manner.

  • You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.
  • Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each \frac{y}{x}
  • When you move up, the number will be positive (\frac{+y}{x}). If you move down, the number will be negative (\frac{-y}{x}).
  • If you move to the right, the number will be positive (\frac{y}{+x}). If you move to the left, the number will be negative (\frac{y}{-x}).
