Answer:
2 sqrt(2x-1)
Step-by-step explanation:
f(x) = sqrt(x+7)
g(x) = 8x-11
f(g(x))=
Place g(x) in for x in the function f(x)
f(g(x)) = sqrt( 8x-11 +7)
= sqrt( 8x -4)
Factor out 4
= sqrt( 4(2x-1)
= 2 sqrt(2x-1)
Answer:
Solution set = (-5, -2)
Step-by-step explanation:
Given equations;
-7x + 8y = 19 ------------- eq1
7x – 9y=-17 --------------- eq2
Adding both equations:
-y = 2
OR
y = 2
Put value of y in eq2:
7x - 9(-2) = -17
7x + 18 = -17
7x = -17 -18
7x = -35
x = -5
Solution set = (-5, -2)
