Quiz
(1.) 9⁴+6⁸ = .....
(2.) Gradient garis 3x+2y=8 adalah....
(3.) Diketahui f(x)=px+q, f(-1)=-5 Dan f(4)=5. nilai f(-6) adalah....​

Penjelasan dengan langkah-langkah:

1.9⁴ + 6^8

= 6.562 + 1.679.616

= 1.686.178

2.3x + 2y = 8

-2y = 3x - 8

gradiennya : 3/-2

3.f(x) = px + q

f(-1) = -5

f(4) = 5

-1p + q = -5

4p + q = 5

_________ -

-5p = -10

p = -10/-5

p = 2

Substitusi :

4p + q = 5

4(2) + q = 5

8 + q = 5

q = 5 - 8

q = -3

f(-6) = 2x + (-3)

f(-6) = 2(-6) - 3

f(-6) = -12 - 3

f(-6) = -15
