1. Set kosong ialah set yang tidak mempunyai sebarang unsur.

benar

palsu

The statement correctly defines an empty set as a set that does not have any elements. This means that there are no objects or elements present in the set. Therefore, the answer "benar" (true) is correct.

2. Nyatakan pernyataan berikut sama ada benar atau palsu.Jika x=2, maka x+14=15

benar

palsu

The statement "Jika x=2, maka x+14=15" translates to "If x=2, then x+14=15" in English. However, when we substitute x=2 into the equation, we get 2+14=16, which is not equal to 15. Therefore, the statement is false.

Explanation

The statement "Jika x=2, maka x+14=15" translates to "If x=2, then x+14=15" in English. However, when we substitute x=2 into the equation, we get 2+14=16, which is not equal to 15. Therefore, the statement is false.

3. Nyatakan pernyataan dan akas berikut sama ada benar atau palsu.Pernyataan: Jika x=2, maka x-1=1Akas: Jika x-1=1, maka x=2

benar

palsu

The given statement and its converse are both true. This can be proven by substituting x=2 into the original equation x-1=1, which gives us 2-1=1, and therefore x=2. Thus, the original statement is true. Additionally, if we assume x-1=1, then by adding 1 to both sides of the equation, we get x=2. Hence, the converse statement is also true.

4. Tukarkan 5193 kepada 3 angka bererti

5100

5190

5200

51960

The given question asks for three significant digits for the number 5193. Among the options provided, only 5190 has three significant digits. The other options either have more than three significant digits or do not match the given number. Therefore, 5190 is the correct answer.

Explanation

The given question asks for three significant digits for the number 5193. Among the options provided, only 5190 has three significant digits. The other options either have more than three significant digits or do not match the given number. Therefore, 5190 is the correct answer.

5. Tukarkan 4000 kepada 1 angka bererti.

4

40

400

4000

The given question asks to convert 4000 into a single significant figure. The only option that satisfies this condition is 4.

Explanation

The given question asks to convert 4000 into a single significant figure. The only option that satisfies this condition is 4.

6. Nyatakan pernyataan berikut sama ada benar atau palsu.24 ialah faktor bagi 2 atau 6+12=24

benar

palsu

The statement is true because 24 is indeed a factor of 2 and 6+12 equals 18. Therefore, the statement is correct.

Explanation

The statement is true because 24 is indeed a factor of 2 and 6+12 equals 18. Therefore, the statement is correct.

7. Nyatakan pernyataan berikut sama ada benar atau palsu. 20 ialah faktor bagi 2 dan 6+12=20

benar

palsu

Pernyataan pertama, “20 ialah faktor bagi 2” adalah palsu. Sebuah nombor adalah faktor bagi nombor lain jika nombor tersebut dapat dibagi habis oleh nombor pertama. Dalam hal ini, 2 tidak dapat dibagi habis oleh 20.

Pernyataan kedua, “6+12=20” juga adalah palsu. Jika kita menjumlahkan 6 dan 12, hasilnya adalah 18, bukan 20.

8. Nyatakan pintasan y bagi persamaan y=4x+1

-4

1

4

-1

The shortcut "y" for the equation y=4x+1 is 1.

Explanation

The shortcut "y" for the equation y=4x+1 is 1.

9. Nyatakan kecerunan bagi garis y=3

0

1

2

3

The given question asks for the slope of the line y=3. In this case, the line is a horizontal line with a constant y-value of 3. Since the line is horizontal, it does not have a slope. The slope of a horizontal line is always 0.

Explanation

The given question asks for the slope of the line y=3. In this case, the line is a horizontal line with a constant y-value of 3. Since the line is horizontal, it does not have a slope. The slope of a horizontal line is always 0.

10. Nyatakan kecerunan bagi garisan y=3x-2

1

2

3

-2

The correct answer is 3 because the gradient of a line with the equation y=mx+c is equal to the coefficient of x, which in this case is 3. Therefore, the gradient of the line y=3x-2 is 3.

Explanation

The correct answer is 3 because the gradient of a line with the equation y=mx+c is equal to the coefficient of x, which in this case is 3. Therefore, the gradient of the line y=3x-2 is 3.
