Answer:
See below
Step-by-step explanation:
Given function is ,
=> f(x) = 4x + 7.
Replace f(x) with y ,
=> y = 4x + 7
For finding the inverse , interchange x and y ,
=> x = 4y + 7
Now solve for y ,
=> 4y = x - 7
=> y = x-7/4
Replace y with f-¹(x) ,
=> f-¹(x) = (x-7)/4
These are the required steps .
What is linear equation?
An equation between two variables that gives a straight line when plotted on a graph.
2x + 5xy - 3 = 0
x (2 + 5y) -3 = 0
x ( 2 + 5y ) = 3
2 + 5y = 3 / x
5y = (3/x) - 2
y = ( (3/x) - 2) / 5
According to the graph i don't think it's a linear equation.
Answer:
131 cm
Step-by-step explanation:
formula for surface area of pyramid is
S = (1/3)Bh
but the base ia a square, so B = 
S = (1/3)
the pic shows h = 8
but we don't know x
do SohCahToa
sin60 = x/8
x = 8sin60
x = 6.92820323 or 7
plug in numbers
S = (1/3)
8
S = 392/3
S = 130.6666667 or 131 cm

Hi there!
I'm unsure if '11/4 pounds' meant '1/4', however, if it did, the answer is 6 pies in total.
Here's how I worked it out:
9 - 1.5 = 7.5 ( 1 )
7.5 - 1.5 = 6 ( 2 )
6 - 1.5 = 4.5 ( 3 )
4.5 - 1.5 = 3 ( 4 )
3 - 1.5 = 1.5 ( 5 )
1.5 - 1.5 = 0 ( 6 )
