Answer:

-4

Step-by-step explanation:

if y = -2 then x = 4

what is y when x = 8

\frac{ - 2}{x}  =  \frac{4}{8}  \\  - 16 = 4x \\ x =  - 4

If one factor of x2 + 2x - 24 is (x+6), what is the other factor?
steposvetlana [31]

Answer:

( x - 4)

Step-by-step explanation:

x² + 2x - 24

From here, you must find the two factors of -24 (the first and third terms' coefficients multiplied together) that add up to 2 (the middle terms coefficient)

( x - 4) ( x + 6)

A trash can in the shape of a cylinder has a radius of 26 cm and a height of 39 cm. Which of the following is closest to the vol
My name is Ann [436]

Answer:

The volume of cylindrical trash is 82,782.96 cm³  .

Step-by-step explanation:

Given as :

The shape of the trash is cylinder

The radius of cylinder = r = 26 cm

The height of cylinder = h = 39 cm

Let The volume of cylindrical trash = v cm³

<u>Now, According to question</u>

volume = \Pi \times radius^{2}\times height

where \pi = 3.14

So, v = 3.14 × r² × h

Or, v = 3.14 × (26)² × (39)

Or, v = 3.14 × 26,364

∴  v = 82,782.96 cm³

So, volume of cylindrical trash = v = 82,782.96 cm³

Hence, The volume of cylindrical trash is 82,782.96 cm³  . Answer
