almond37 [142]

Answer:

D

Step-by-step explanation:

If you are told that the slope is 2 that means that the equation cannot be A.

The slope is the number in front of the x. So far what you know is that

y = 2x + b

b is found from the given point.

  • x = - 8
  • y = 7
  • 7 = 2*(-8) + b                 Expand the right side
  • 7 = - 16 + b                    Add 16 to  both sides
  • 7+16 = -16 + 16 + b        
  • 23 = b

answer y = 2x + 23

The answer is D

What is the standard form polynomial representing the volume of this shipping container?
harina [27]

Answer:

Volume = (24x⁵ + 78x⁴ - 147x³ - 624x² - 360x)

Step-by-step explanation:

Container given in the picture is in the shape of a cuboid.

And volume of a cuboid is measured by the expression,

Volume of a cuboid = Length × width × height

Now substitute the measure of the container's dimensions given in the picture

Volume = (4x² + 3x)(x²- 8)(6x + 15)

             = [(4x² + 3x)(x²- 8)](6x + 15)

             = [4x²(x² - 8) + 3x(x² - 8)](6x + 15)

             = (4x⁴ - 32x² + 3x³ - 24x)(6x + 15)

             = (4x⁴ + 3x³ - 32x² - 24x)(6x + 15)

             = 6x(4x⁴ + 3x³ - 32x² - 24x) + 15(4x⁴ + 3x³ - 32x² - 24x)

             = 24x⁵+ 18x⁴ - 192x³ - 144x² + 60x⁴ + 45x³ - 480x² - 360x

             = 24x⁵ + 78x⁴ - 147x³ - 624x² - 360x
