Answer:

Bicycle: 30 miles/hour

Scooter: 40 miles/hour

Step-by-step explanation:

Let the speed of the bicycle be s,

Then the speed of the scooter is:

s + 10

Distance = speed × time

Distances covered:

Bicycle: (s)(5½) = 5.5s

Scooter: (s + 10)(3) = 3s + 30

Total:

5.5s + 3s + 30

8.5s + 30

8.5s + 30《285

8.5s《255

s《30

s + 10《40

Choose the linear inequality that describes the graph. The gray area represents the shaded region.
jek_recluse [69]

Answer:

2x + 3y ≥ 5

Step-by-step explanation:

See the graph attached.

The bold straight line passes through the points (1,1) and (4,-1).

Therefore, the equation of the straight line will be  

\frac{y + 1}{- 1 - 1} = \frac{x - 4}{4 - 1}

⇒ 3(y + 1) = - 2(x - 4)

⇒ 3y + 3 = - 2x + 8

⇒ 2x + 3y = 5 ............. (1)

Now, the shaded region i.e. the solution to the inequality does not include the origin(0,0).

So, putting x = 0 and y = 0 in the equation (1) we get, 0 < 5

Therefore, the inequality equation is 2x + 3y ≥ 5 (Answer)
