Answer:

70

Step-by-step explanation:

Since these two are same side interior angles, their measures must be supplementary. This means that they must add up to 180 degrees. Therefore:

45+2x-5=180

2x+40=180

2x=140

x=70

7,013 ×10⁷ as a whole number​
Charra [1.4K]

Answer:

70130000000

Step-by-step explanation:

(Assuming that that 7013 is supposed to be 7013 not 7.013), We will move the decimal place to the right 7 times, since it is 10 to the power of 7. Since the decimal place is at the end of the number, we have to add 7 zeros. This becomes 70130000000.

F (x) = 2 (x + 1)^2 - 1
Ivenika [448]

Answer:

Equation: y = x²

  • (-2, 4)
  • (0, 0)
  • (2, 4)

Equation: f(x) = 2(x + 1)² - 1

  • (-2, 1)
  • (0, 1)
  • (2, 17)

Step-by-step explanation:

Equation: y = x²

  • when x = -2, y = (-2)² = 4 ⇒ (-2, 4)
  • when x = 0, y = (0)² = 0 ⇒ (0, 0)
  • when x = 2, y = (2)² = 4 ⇒ (2, 4)

Equation: f(x) = 2(x + 1)² - 1

f(-2) = 2(-2 + 1)² - 1

      = 2(-1)² - 1

      =2(1) - 1

     = 1

Therefore, (-2, 1)

f(0) = 2(0 + 1)² - 1

     = 2(1)² - 1

      =2(1) - 1

     = 1

Therefore, (0, 1)

f(2) = 2(2 + 1)² - 1

     = 2(3)² - 1

      =2(9) - 1

     = 17

Therefore, (2, 17)
