7. Answer:  +4,      x ≥ 16

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

x - 4 ≥ 12

Add 4 to both sides (to isolate the variable):

x - 4 <u>+ 4</u> ≥ 12 <u>+ 4</u>

x             ≥ 16

Graph has a closed dot with an arrow pointing to the right of 16.

16 ·------------→

9. Answer:  x ≤ 9

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

x - 20 ≤ -11

Add 20 to both sides of the equation:

x -20 +20  ≤ -11 +20

x                 ≤ 9

Graph has a closed dot with an arrow pointing to the left of 9.

A card is drawn from a pack of 52 cards. Find the probability of drawing an ace given that it is diamond.4/521/132/134/13
ICE Princess25 [194]

Solution:

The probability of an event is expressed as

P(event)=\frac{number\text{ of desired outcome}}{number\text{ of possible outcome}}

In a pack of 52 cards, we have

\begin{gathered} number\text{ of diamonds=13} \\ number\text{ of ace= 1} \end{gathered}

Thus, we have the probability to be evaluated as

P(ace)=\frac{1}{13}

Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the
Zanzabum

Answer:

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule R(O,90^\circ)\circ r_{y=-x}(x,y). Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to r_{y=-x}(x,y), we get

(x,y)\rightarrow (-y,-x)

According to R(O,90^\circ), we get

(x,y)\rightarrow (-y,x)

The rule R(O,90^\circ)\circ r_{y=-x}(x,y) means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

K(4,7)\rightarrow K'(-7,-4)

After rotation, we get

K'(-7,-4)\rightarrow K''(4,-7)

Therefore, the correct option is C.

The 4rth place is '4'(as it is lesser than 5) the 3rd decimal place will become 3.
