Answer:

y = 2x + 4

Step-by-step explanation:

4x - 2y = -8

Then subtract 4x from both side which will give you

-2y = -4x - 8

then divide -2 from both sides which will give you

y = 2x + 4

slope: 2

y intercept: 4

A cylinder has a radius of 5x + 4 and a height of 2x + 5. Which polynomial in standard form best describes the total volume of t
Nana76 [90]

Answer:

Step-by-step explanation:

Volume = pi·(r^2)*h

r = radius = (5x+4)

h = height = (2x+5)

 

Volume = pi·(r^2)

Volume = pi·(5x+4)^2*(2x+8)

Volume = pi·(25x^2+40x+16)*(2x+8)

Volume = pi·(50x^2+80x+32+200x^2+32x+128)

Volume = pi·(250x^2+112x+160)

10 to the power of 3 times what equals 630
vekshin1
10³ · x = 630
x = ?

10³ = 10 × 10 × 10 = 1,000

630 ÷ 1000 = x
630 ÷ 1000 = 0.63
x = 0.63

So we have:

10³ · 0.63 = 630
