Answer:
y=1
Step-by-step explanation:
y = 11x + 1
11x + 12y = 12
Take the right side of the first equation, which is 11x + 1,
since y equals it, put it in parentheses like this (11x + 1)
and put it in place of y in the second equation.
The second equation is
11x + 12y = 12
Take out the y and put in (11x + 1) in place of the y:
11x + 12(11x + 1) = 12
Remove the parentheses by using the distributive principle:
11x + 132x + 12 = 12
Combine like terms on the left
143x + 12 = 12
Subtract 12 from both sides
143x = 0
Divide both sides by 143
x = 0
Now go back and get the very first equation:
y = 11x + 1
And substitute (0) for x:
y = 11(0) + 1
y = 0 + 1
y = 1
So from what I understand of the problem, the tv costs $850 at a discounted price of 20%. and other than the 20%, you can get an additional discount of 15% at the counter. So to solve this, you can just simply multiply 850 with 35% or 0.35. The answer to that will be $297.5. Now you then have to less this amount with 850. The final answer to that is 552.5. So after all the discounts that you have received from the store, then the final price that you can get for this tv set would be $552.5
The correct answer is A.
lets discard the other options:
For B:
B is always positive, but f(x) is not, so B graph is not the answers
For C:
C is always positive too, so it cannot be the desire graph.
For D:
D is always negative, but we know that x exponent 3 is positive for all positive numbers,
Answer:
I believe option D is the answer
