Question

Tolong jawab nomor 13,14,15
Bsok dikumpul

Answer 1

13) h(x) = 17 - 4x
*h(a) = -3
-3 = 17 - 4a
-20 = -4a
a = 5
*h(b) = 13
13 = 17 - 4b
-4 = -4b
b = 1
nilai 2a - b = 10 - 1 = 9

14) f(x) = 13x - 45
f(C) = -2C
-2C = 13C - 45
-15C = -45
C = 3

15) g(x) = 3px² - 8
g(-3) = 28
28 = 3p(3)² - 8
36 = 3p × 9
36 = 27p
p = 36/27
p = 4/3
p = 1 1/3
