Answer:
3 bags of chocolate chips and 3 bags of walnuts
Step-by-step explanation:
1 pound = 16 ounces (oz). So, our dear Jemina needs 48 ounces. Then, we do system of equations. one of the equations are 3x +2y = 15(dollars), and then second is 12x + 4y = 48. (ounces/pound). Let's solve for x first. We multiply the dollars equation by 2 to eliminate y from both equations. 6x +4y = 30. When you subtract, you get 6x = 18. So, x = 3, Jemina buys 3 chocolate chips bags. So, thats $9. So, she also spends $6 on walnuts. For checking, 3 bags of chocolate chips = 36 ounces. 3 bags of walnuts = 12 ounces. 36+12 ounces = 48 ounces. :D
Answer:
x = 112, y = 68, z = 112
Step-by-step explanation:
y = 68
x = z = 180 - 68 = 112
The number places go ones, tens, hundreds, thousands, ignore the decimals
Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values, 
and 
, that have the same output value y
Note that the function 
is not a one-to-one function
When x=2 
When x=8 
Note that the function 
is not a one-to-one function
When x=1 
When x=-1 
Note that the function 
is not a one-to-one function
When x=1 
When x=-1 
Then the answer is the option B.
You can verify that The function 
is a one-to-one function and therefore its inverse is a function
The answer is 7 h...Hope it works :)
