Answer:
x= 2, y= 1
Step-by-step explanation:
x= 2y
2x +5y =9
substitute x
2 *2y +5y = 9
4y +5y = 9
9y = 9
y =1
x= 2*y = 2*1= 2
Answer:

Step-by-step explanation:
The given function are;
f(x) = x² - 3·x - 12, and g(x) = -x - 12

Therefore;

g(-8) = -(-8) - 12 = 8 - 12 = -4
∴ f(g(-8)) = f(-4) = (-4)² - 3×(-4) - 12 = 16
Therefore;

Answer:
c) 15
Step-by-step explanation:
Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
