<u>Given</u>:
The given inequality is
We need to determine the graph that fits the inequality.
<u>Graph of the inequality:</u>
The inequality means that x is greater than 4. This means that the end value 4 is not included.
To graph the inequality " > " a dashed line is used.
The inequality does not contain any y - value in it.
Hence, it has only one vertical line at and is shaded for all values of x greater than 4.
Therefore, the graph that fits the inequality is a vertical dashed line, shaded to the right of the line.
Thus, Option d is the correct answer.
Answer:
2.(b) w= 3
3. x= -3 or x= 3
Step-by-step explanation:
2.(b) <u>Method 1:</u>
Simplify:
×5 on both sides:
Expand:
Bring constants to 1 side, w terms to the other:
Simplify:
Divide both sides by 3:
<u>Method 2:</u>
Multiply by 5 throughout:
Expand:
Simplify:
+9 on both sides:
-4w on both sides:
Simplify:
Divide by 3 on both sides:
3.
Multiply by 3x on both sides:
Expand:
Simplify:
Divide by 6 on both sides:
-9 on both sides:
Factorise:
*Since a²-b²= (a +b)(a -b),
Thus,
x +3= 0 or x -3= 0
x= -3 or x= 3
As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number of places to the right. A negative exponent shows that the decimal point is shifted that number of places to the left.
In scientific notation, the digit term indicates the number of significant figures in the number. The exponential term only places the decimal point. As an example,
<span>46600000 = 4.66 x 107 </span>This number only has 3 significant figures. The zeros are not significant; they are only holding a place. As another example,<span>0.00053 = 5.3 x 10<span>-4 </span></span><span>This number has 2 significant figures. The zeros are only place holders.</span>
