Answer:
The answere is (9,3)
Step-by-step explanation:
first equation
x - 2y = 3
9 - 2(3) = 3
9-6 = 3
3 = 3
second equations
2x - 3y = 9
2(9) - 3(3) = 9
18 - 9 =9
9 = 9
or
x - 2y = 3
x = 2y + 3
2(2y + 3 ) - 3y = 9
4y +6 - 3y = 9
y + 6 = 9
y =3
x - 2(3) = 3
x - 6 =3
x = 9
so (9,3)

Answer: one third. one half and 1 whole
Step-by-step explanation:
The value of (f - g)(x) is -x² + 3x + 7.
<h3>What is Function?</h3>
The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, the given functions are;
f(x) = 3x + 1
g(x) = x² - 6
Now,
(f - g)(x) = f(x) - g(x)
= (3x + 1) - (x² - 6)
= 3x + 1 - x² + 6
(f - g)(x) = -x² + 3x + 7
Thus, the value of (f - g)(x) is -x² + 3x + 7.
