Well i guess 8 because 4/5 = 8/10 and 8/10 = .8 so yea
System of Linear Equations entered :
[1] 5x - 6y = 7
[2] 6x - 7y = 8
Graphic Representation of the Equations :
-6y + 5x = 7 -7y + 6x = 8
Solve equation [2] for the variable x
[2] 6x = 7y + 8
[2] x = 7y/6 + 4/3
// Plug this in for variable x in equation [1]
[1] 5•(7y/6+4/3) - 6y = 7
[1] - y/6 = 1/3
[1] - y = 2
// Solve equation [1] for the variable y
[1] y = - 2
// By now we know this much :
x = 7y/6+4/3
y = -2
// Use the y value to solve for x
x = (7/6)(-2)+4/3 = -1
Answer:
3/5
Step-by-step explanation:
this is the correct answer because a is represented by the number picked is greater than 7.
3/10 are less than 7
2/5 are less than 7
but 3/5 are more than 7
so the answer is 3/5

Since it is f of g you have to start by plugging in g(x) into f(x)
(4-3x)^2-3
Then just solve the equation
(4-3x)^2-3
(4-3x)(4-3x)-3 Square the binomial
8-12x-12x+9x^2-3 Combine like terms
5-24x+9x^2 Final answer
