Find the slope of the equations:

1 answer:

4 0

3. 2x - y = 10
    2x - 2x - y = -2x + 10
   -y = -2x + 10
   -1    -1
   y = 2x - 10
   Slope: 2

4. 5x - 2y = 10
    5x - 5x - 2y = -5x + 10
   -2y = -5x + 10
      -2 -2
      y = 2.5x - 5

5. y - y₁ = m(x - x₁)
    y - (-2) = -3(x - (-1))
   y + 2 = 3(x + 1)
   y + 2 = 3(x) + 3(1)
   y + 2 = 3x + 3
   - 2    - 2
   y = 3x + 1

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 uni

Answer:

Step-by-step explanation:

So basically you need to use the pythagorean thrm. Essentially, the diagonal and the width and length create a triangle, the diagonal being the hypothenuse. So the formula goes as $\sqrt[]{a^{2} +b^{2} }$ . the variable "a" being the length and the variable "b" being the width. So plug it in and there you have your answer!
