Question: Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using function notation. Answer: This function can be written using the following function notation: f(x)=__ x + 4 ; f(x)= -3x+4
y = -2(x-4)2-6
= -4(x-4) - 6
= -4x + 16 -6
y = 10- 4x
now if x is positive, x >= 0
then max value of y will be when x will nr minimum
so max y = 10- 4×0 = 10
so y = 10 at x =0 for x >=0
if x < 0 then
y will be increasing as x gets increase towards more negative. so max of y will be decided when x reaches to max negative.
The perimeter of the octagon is 8 times the side
p=25*8=200 cm
200cm=2 m
Answer: infinity or false
Step-by-step explanation:
Width = w
d)length in term of width
w + 5
b)
2(w + w + 5) > 30
2(2w +5)>30
c)
solve
2(2w +5) > 30
4w + 10 > 30
4w > 20
w > 5
