Answer:

Here, answer is given in form of 4 figure labelled with inequality

Step-by-step explanation:

Given inequality are

A). 2x>(-6)

B). 6+x\leq 3

C). x-4

D). -x-5\leq (-2)

For matching with givens graph:

Simplifying...

A). 2x>(-6)

Divide 2 on both sides

x>(-3)

B). 6+x\leq 3

Add (-6) on both side.

6+x+(-6)\leq 3+(-6)

x\leq(-3)

C). x-4

Add (4) on both side.

x-4+4

x

D). -x-5\leq (-2)

Multiple (-1) on both side

+x+5\geq (+2)

Note :  Change of inequality sign due to multipication of negative number

Add (-5) on both side.

x\geq (-3)

Here, Answer is given in form of 4 figure labelled with inequality

lina2011 [118]

Answer:

Time taken by the un powered raft to cover this distance is T = 192.12 hr

Step-by-step explanation:

Let speed of boat = u \frac{km}{hr}

Speed of current = v \frac{km}{hr}

Let distance between A & B = 100 km

Time taken in downstream = 32 hours

32 = \frac{100}{u +v}

u + v = \frac{100}{32}

u + v = 3.125 ------ (1)

Time taken in upstream = 48 hours

48 = \frac{100}{u -v}

u -v = \frac{100}{48}

u - v = 2.084 ------- (2)

By solving equation (1) & (2)

u = 2.6045 \frac{km}{hr}

v = 0.5205 \frac{km}{hr}

Now the time taken by the un powered raft to cover this distance

T = \frac{100}{v}

Because un powered raft travel with the speed of the current.

T = \frac{100}{0.5205}

T = 192.12 hr

Therefore the  time taken by the un powered raft to cover this distance is

T = 192.12 hr
