9. find the value of x for |2x-1|=|3x|+3
|2x-1|=|3x|+3
-1-3 =3x-2x
-4 =x
x =-4
|2x - 1| = |3x| + 3
2x - 1 = 3x + 3
2x - 3x = 3 + 1
-x = 4
x = -4
10. What is the value of x for the equation 5(3x-2) + 6(4x-3) = 11 ?
5(3x-2) + 6(4x-3) = 11 ?
(5.3x) - (5.2) + (6.4x) - (6.3) = 11
15x - 10 + 24x - 18 = 11
15x + 24x - 10 - 18 = 11
39x - 28 = 11
39x = 11 + 28
39x = 39
x = 39/39
x = 1
So the value of x is 1

14. What is the value of x in 3(x-4) =-20
Kelas 7 Matematika
Bab Persamaan Linear
3 (x - 4) = -20
3x - 12 = -20
3x = -20 + 12
x = -8/3Jawaban :
3(x-4) = - 20
3x - 12 = - 20
3x = -20 + 12
3x = -8
x = -8/3
x = - 2 2/3

18. prove that the value of (p-x)²+(q-x)²-2(p-x)(q-x) does not depend on the value of x
(p-x)^2 + (q-x)^2 - 2(p-x)(q-x) = [(p-x)-(q-x)]^2
= [p-x-q+x]^2
(p-x)^2 + (q-x)^2 - 2(p-x)(q-x) = [p-q]^2 (proved)
langsung di jabarkan
p°°-x°°+q°°-x°°-2p.2x-2q+2x
= p°°-x+q-2p.4x+2q
p°°-x.4x-2p+2q
=p°°-4x-2p+2q
pindah posisi dimana mana x di depan
-4x+p°°-2p+2q atau 4x-p°°+2p-2q
19. what is the value of x?
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
[tex] \frac{ {2}^{x + 2} + {2}^{x + 4} + {?}^{x + 6} }{128} = \frac{21}{2} [/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = \frac{21}{2} \times 128[/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = 1344[/tex]
[tex](1 + {2}^{2} + {2}^{4} ){2}^{x + 2} = 1344[/tex]
[tex](1 + 4 + 16) {2}^{x + 2} = 1344[/tex]
[tex]21 \times {2}^{ x + 2} = 1344[/tex]
[tex] {2}^{x + 2} = \frac{1344}{21} [/tex]
[tex] {2}^{x + 2} = 64[/tex]
[tex] {2}^{x + 2} = {2}^{6} [/tex]
[tex]x + 2 = 6[/tex]
[tex]x = 6 - 2[/tex]
[tex]x = 4[/tex]
jadi, nilai x adalah 4
20. the value of the function formula of h(x)=ax+9.The value of function h for x=3 is -6
.............................h(x)=ax+9
h(-3)=ax+9=-6
=a(-3)+9=6
=-3a+9=6
jika ingin mencari a, berarti :
=-3a+9=6
=-3a=6-9
=-3a=-3
=a=1
maaf jika salah
