Start by solving the inequality for r.  You do this like you would solve any other two step equation:

<em>*Subtract 7 from both sides*</em>

r/4≥-1

<em>*Multiply both sides by 4*</em>

r≥-4


To graph this, you will start at -4.  You need to determine whether you will draw an open or a closed circle at -4.  An closed circle is drawn when the inequality is greater than or <u>equal to</u> (it includes the value at the circle).

Draw a closed circle at -4.

Next, you need to determine which way to draw the arrow.  If it is greater than, you draw an arrow to the right; if it is less than, the arrow is to the left.

Draw an arrow to the right.


Hope this helps!

Step-by-step explanation:

1/4 r+7≥6

Step 2: Subtract 7 from both sides.

1/4 r+7−7≥6−7

1/4 r≥−1

Step 3: Multiply both sides by 4.

4*(1/4r)≥(4)*(−1) r≥−4

Answer:

r≥−4

On a trip, a motorist drove 150 miles in the morning and 50 miles in the afternoon. His average rate in the morning was twice hi
Lina20 [59]

Answer:

Morning's average rate = 50 mph, and Afternoon's average rate = 25 mph.

Step-by-step explanation:

Suppose he drove 150 miles for X hours, then his average rate in the morning was (150/X) mph.

Given that he spent 5 hours in driving.

And he drove 50 miles for (5-X) hours, then his average rate in the afternoon was 50/(5-X) mph.

Given that his average rate in the morning was twice his average rate in the afternoon.

(150/x) = 2 * 50/(5-x)

150/x = 100/(5-x)

Cross multiplying terms, we get:-

150*(5-x) = 100*x

750 - 150x = 100x

750 = 100x + 150x

750 = 250x

x = 750/250 = 3.

It means he spent 3 hours in the morning and 2 hours in the afternoon.

So morning's average rate = 150/3 = 50 mph.

and afternoon's average rate = 50/(5-3) = 25 mph.

Help me please with some of my math homework I don’t really understand what p is equal to
horrorfan [7]

The value of p is 5.

<u>Step-by-step explanation</u>:

<u>step 1</u> : The given expression is -6( p -5 )

<u>step 2</u> : To find any unknown value in an expression, equate it to zero.

<u>step 3</u> : -6( p -5 ) = 0

<u>step 4</u> : Multiply -6 to each term in the bracket.

            -6p + 30 = 0

            -6p = -30

              p = -30/-6

              p = 5
