Answer:
1) 
2) 
3) 
Step-by-step explanation:
Given : A certain economy's consumption function is given by the equation 
where, C(x) is the personal consumption expenditure in billions of dollars, and x is the disposable personal income in billions of dollars.
To find :
1) C(0)
Put x=0 in the given equation,
2) C(50)
Put x=50 in the given equation,
3) C(100)
Put x=100 in the given equation,
2/2, 4/4, 5/5, 7/7, or any fraction with the same numerator and denominator will be equivalent. All fractions equal 1.
Answer
X= -0.5
Y=2
If you need me to explain I can.
Let n = cost of 1 notebook
Let p = cost of 1 pencil
Then,
3n + 4p = 8.5
5n + 8p = 14.5
You can solve for one variable in terms of the other and then substitute into the remaining equation.
3n + 4p = 8.5
+ 5n + 8p = 14.5
Multiply the top equation by -2 so that the p-containing terms cancel each other out:
-2(3n + 4p = 8.5)
+ 5n + 8p = 14.5
-n + 0 = -2.5
So after dividing both sides by -1, we see that n = $2.5. Plugging into the first equation gives p = $0.25.
3n + 4p = 8.5
5n + 8p = 14.5
