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

What is the solution of the system of equations?
Elis [28]

Answer:

The answer to your question is:

x = 4

y = -1

z = -3

Step-by-step explanation:

                                  3 x + 2 y + z = 7

                                  5 x + 5 y + 4 z = 3

                                  3 x + 2 y + 3 z = 1

\left[\begin{array}{ccc}3&2&1\\5&5&4\\3&2&3\end{array}\right]

= 45 + 10 + 24 - (30 + 24 + 15)

= 79 - 69

Δ = 10

\left[\begin{array}{ccc}7&2&1\\3&5&4\\1&2&3\end{array}\right]

= 105 + 6 + 8 - (18 + 56 + 5)

= 119 - 79

Δx = 40

\left[\begin{array}{ccc}3&7&1\\5&3&4\\3&1&3\end{array}\right]

= 27 + 5 + 84 - ( 105 + 12 + 9)

= 116 - 126

Δy = -10

\left[\begin{array}{ccc}3&2&7\\5&5&3\\3&2&1\end{array}\right]

= 15 + 70 + 18 - (10 + 18 + 105)

= 103 - 133

= -30

Δz = -30

x = Δx /Δ = 40/10 = 4

y = Δy/Δ = -10/10 = -1

z = Δz/Δ = -30/10 = -3

Modular arithmetic<br> Pls a little explaine it
fredd [130]

Step-by-step explanation:

(72)¹⁴³ ≡ x (mod 7)

Since 72 ≡ 2 (mod 7),

72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).

Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)

≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

The answer is A.
