Hitunglah nilai dari integral 2 dan 1 integral 4 dan 2 (x+2y) dx dy

I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
-1/2x - 7 = -11
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : *** x = 8***
Take it Allalala !

− 2 1 ​ x − 7 = − 11 \
− 2 1 ​ x = − 11 + 7 |adding 7 on both sides
− 2 1 ​ x ∗ 2 = − 4 ∗ 2 |multiplying by -2 on both sides
− x = − 8 |dividing by -1 on both sides
x = 8
So, the solution is x =8

The solution to the equation − 2 1 ​ x − 7 = − 11 is x = 8 . After solving and substituting back into the original equation, both sides match, confirming the solution is correct. Therefore, x = 8 is the valid answer.

Hitung nilai dari:∫ dari y = 1 sampai 2 ∫ dari x = 2 sampai 4 (x + 2y) dx dyLangkah 1: Hitung integral dalam (terhadap x)∫(x = 2 to 4) (x + 2y) dxKarena 2y dianggap konstan terhadap x:= ∫(2 to 4) x dx + ∫(2 to 4) 2y dx= [1/2 x^2] dari 2 ke 4 + 2y [x] dari 2 ke 4= (1/2)(16) - (1/2)(4) + 2y(4 - 2)= 8 - 2 + 4y = 6 + 4yLangkah 2: Hitung integral luar (terhadap y)∫(y = 1 to 2) (6 + 4y) dy= ∫(1 to 2) 6 dy + ∫(1 to 2) 4y dy= 6[y] dari 1 ke 2 + 4 * [1/2 y^2] dari 1 ke 2= 6(2 - 1) + 4 * (1/2)(4 - 1)= 6 + 2 * 3 = 6 + 6 = 12Jawaban akhir:12
