Let's say, the number is x.

2x + 15 ≤ (-7 - x )

2x + x ≤ -7 - 15

3x ≤ -23

x ≤ -23 / 3

8(3n + 5) = -32<br> what does n =
olga_2 [115]

Answer: n = -3

Step-by-step explanation:

8(3n + 5) = -32

  • <em>Divide both sides by 8.</em>

(3n + 5) = -4

  • <em>Subtract 5 by both sides.</em>

3n = -4 - 5

3n = -9

  • <em>Divide both sides by 3.</em>

n = -3

grandymaker [24]

Answer:

  • 2 seconds
  • 72 feet

Step-by-step explanation:

The usual equation used for the vertical component of ballistic motion is ...

  h(t) = -16t² +v₀t +h₀

where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.

Your problem statement gives ...

  v₀ = 64 ft/s

  h₀ = 8 ft

so the equation of height is ...

  h(t) = -16t² +64t +8

__

For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...

  t = -64/(2(-16)) = 2

The object will reach its maximum height after 2 seconds.

The height at that time will be ...

  h(2) = -16(2²) +64(2) +8 = 72

The maximum height will be 72 feet.

Find (f/g)(x).<br>Please help !!
Setler [38]

Answer:D

Step-by-step explanation:

factorise 2x²-16x+32

x²-8x+16

(x-4)²

factorise 4x²-2x-20

2x²-x-10

2x²+4x-5x-10

2x(x+2)-5(x+2)

(2x-5)(x+2)

solving for (f/g)(x)

(x-4)²/(x+2)÷(2x-5)(x+2)/(x-4)²

(x-4)²/(x+2)*(x-4)²/(2x-5)(x+2)

(x-4)⁴/(2x-5)(x+2)²
