4. What is the result of 3^2x-5x+1 from 8x^2 -2x-9? a. 5x2 +3x - 10
b. -5x2-3x -10
C. 5x2 -7X-8
d. 5x2 -7x +8

a)  5 x² + 3 x -10

Step-by-step explanation:

Explanation:-

Given polynomials

        3 x² - 5 x + 1   and 8 x² - 2 x -9

Given that  

         3 x² - 5 x + 1   From 8 x² - 2 x -9

  ⇒   8 x² - 2 x -9 - (  3 x² - 5 x + 1  )

  =    8 x² - 2 x -9 - 3 x² + 5 x - 1

  =    5 x² + 3 x -10

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
