Hi
We need to solve 3x-7=2 for x
Let's start by adding 7 to both sides
3x-7+7=2+7
3x=9
Now just divide both sides by 3 so we can find the value for x
3x/3=9/3
x=3
Now substitute 3 for x in 4x-y=5 so we can find the value for y
4x-7=5
4(3)-y=5
-y+12=5
Add -12
-y+12-12=5-12
-y=-7
Now divide both sides by -1 so we can find the positive value for y
-y/-1=-7/-1
y=7
The answer is A

The value of g(f(-3)) would be -9 which is the correct answer would be an option (B).
What exactly is a function?
A function is defined as a mathematical phrase that specifies a connection between two variables in algebra.
We have been given the functions below as
f(x) = 3x + 7 and g(x) = 2x - 5
We have to determine the value of g(f(-3))
Substitute the value of f(x) = 3x + 7 in the g(x) = 2x - 5 to get g(f(x))
⇒ g(f(x)) = 2(3x + 7) - 5
Apply the distributive property of multiplication,
⇒ g(f(x)) = 6x + 14 - 5
⇒ g(f(x)) = 6x + 9
Substitute the value of x = -3 in the g(x) = 2x - 5 to get g(f(-3))
⇒ g(f(-3)) = 6(-3) + 9
⇒ g(f(-3)) = -18 + 9
⇒ g(f(-3)) = -9
Therefore, the value of g(f(-3)) would be -9.

f(x) when f(x) >= 0 OR -f(x) when f(x)< 0
so |x-11| > 4 is equivalent to
x-11 > 4 when x-11 >= 0 OR
-(x-11) > 4 when x-11 < 0
rearrange
x-11 > 4 when x-11 >= 0 we get
x > 15 when x >= 11 ... means x > 11
-(x-11) > 4 when x-11 < 0 we get
x < 7 when x < 11 ...means x < 7
so we have. x < 7 OR x > 11 for this inequality which is not the correct answer
... now... what is solution for |x-11| < 4
you can try to work as above and should come up with the solution just 'the opposite' which is x > 7 OR x < 11 [ 7 < x < 11 ]
then you work for c) and could work or guess for d)
