Answer:
f(x)=3x+2,g(x)=2x^(2)-1
Step-by-step explanation:
First set up the composite result :
f (g (x))
Evaluate f (g (x))
3( 2x sqaured -1 ) + 2
Simplify:
f ( 2X SQUARED -1 ) 6 x squared -3 + 2
Add 2 and -3
90+(2x+15)+x=180
90+2x+15+x=180
105+3x=180
3x=75
x=75/3
x=25degree
First piece is x
second piece is y. y=4x
third piece is z. z=3y=12x
x+y+z=680
x+4x+12x=680
17x=680. x=40cm y=160cm. z=480cm
Answer:
−4<x≤9
Conjunction
Step-by-step explanation:
-7 < x -3
x -3 ≤ 6
-7 + 3 < ( x - 3) + 3
(x -3) + ≤ 6 + 3
-4 < x -3 + 3
x - 3 + 3 ≤ 9
-4 < x
x ≤ 9
x > -4
x ≤ 9
Answer:
I'm guessing the right answer should be B
