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