Ini gimana cara nya ?
thx

Answer 1

Verified answer

4) h(x) = 4x + 5
a) h(n) = 4n + 5 = 29
4n = 29 - 5
4n = 24
n = 6
b) h(n) = 4n + 5 = 3
4n = 3 - 5
4n = - 2
n = - 2/4
n = - ½

5) g(x) = 2x² - 7
a) g(6) = 2(6)² - 7 = 2(36) - 7 = 72 - 7 = 65
g(-4)² = 2(-4)² - 7 = 2(16) - 7 = 32 - 7 = 25
b) g(a) = 2a² - 7 = 11
2a² = 11 + 7
2a² = 18
a² = 18 ÷ 2
a = √9
a = 3

Answer 2

4.a) 4x+5=29 
       4x=24
         x=6
   b) 4x+5=3
       4x=-2
         x=-1/2
5.a)  2(6)^2-7
      =2.36-7
      =65
        2(-4)^2-7
      =-35
    b.)  2(a)^2-7=11
        =2a^2-7=11
        =2a^2=18
        =a^2=9
        =a=3
Semoga bener :p
