Latihan Soal Matematika Kelas 7 SMP Semester 1 Kurikulum Merdeka 2023 Lengkap Jawaban & Pembahasan

Maka nilai dari (A ∩ B) ialah ….

A. {4, 8, 10}
B. {1, 2, 3, 5, 6, 7, 9}
C. {3, 4, 5, 7, 8, 10}
D. {3, 5, 7}

Jawaban: D

A = {1, 3, 5, 6, 7, 9}
B = {2, 3, 5, 7}
A ∩ B = {3, 5, 7}

4. Apabila diketahui A = {1, 3, 5, 7, 9} sedangkan nilai B = {0, 3, 6, 9}, maka nilai (A ∪ B) ialah ….
A. {0, 1, 3, 5, 6, 7, 9}
B. {1, 3, 5, 6, 7, 9}
C. {0, 1, 3, 5, 6, 7}
D. {3, 9}

Jawaban: A

A = {1, 3, 5, 7, 9}
B = {0, 3, 6, 9}
A ∪ B = {0, 1, 3, 5, 6, 7, 9}

5. Jika diketahui : {x | -1 ≤ x <3>A. {-1, 0, 1, 2, 3}
{0, 1, 2, 3}
C. {-1, 0, 1, 2}
D. {1, 2}

Jawaban: D

Diketahui : {x | -1 ≤ x <3>
: {1, 2}
