third option is the correct answer....
Answer:
4x-2y =42 is the required equation
Step-by-step explanation:
given equation is,
4x-2y -7=0---------eqn1
parallel equation of given equation is
4x -2y+k =0-------eqn 2
now passing it through (9,-3), we get,
4×9 + 2×3 +k = 0
or,36+6+k =0
or,42+k =0
or, k= -42
putting the value of k in eqn2
4x-2y - 42=0
4x-2y = 42
Answer:
Step-by-step explanation:
The answer to the question is Robert grew 1 2/3 inch taller that his brother
Y=sqrt(3x+4)
3x+4 must be positive
3x+4>=0
Solving for x:
3x+4-4>=0-4
3x>=-4
3x/3>=(-4)/3
x>=-(4/3)
Domain of the function = [-(4/3), +Infinite)
