Answer:

x=5 and -17/4

Step-by-step explanation:

The two equations for 丨4x - 1丨= 19 is

4x-1=19

and

4x-1=-19

So for 4x-1=19

4x=20

x=5

4x-1=-18

4x=-17

x=17/4

yulyashka [42]

Step-by-step explanation:

A = A₀ ½^(t / T)

where A is the amount left, A₀ is the original amount, t is time, and T is the half life.

4 days is 96 hours, so the amount left is:

A = 600 ½^(96 / 15)

Vesna [10]

Let time be t , distance be d

160t=d-(1)
230t=210-d-(2)

Put value in eq(2)

$\\ \rm\longmapsto 230t=210-(160t)$

$\\ \rm\longmapsto 70t=210$

$\\ \rm\longmapsto t=30min$

Answer:

a ) y = 2,

b ) x = 5,

c ) x = - 3,

d ) y = 4

Step-by-step explanation:

a )

$( - 3, - 4 ), ( 0, y )\\Slope = - 4 - y / - 3 - 0\\2 = - 4 - y / - 3,\\\\- 6 = - 4 - y,\\- y = - 2\\\\y = 2$

b )

$( - 2, 2 ), ( x, 5 )\\Slope = 2 - 5 / - 2 - x,\\3 / 7 = - 3 / - 2 - x,\\\\( Algebra ) x = 5$

c )

$( x, 5 ), ( 1, - 5 )\\Slope = 5 - ( - 5 ) / x - 1\\- 5 / 2 = 5 + 5 / x - 1,\\- 5 / 2 = 10 / x - 1\\\\( Algebra ) x = - 3$

d )

$( -6, y ), ( 8, 2 )\\Slope = y - 2 / - 6 - 8,\\- 1 / 7 = y - 2 / - 14\\\\( Algebra ) y = 4$

Hope that helps!
