Number the tables as follows:
1 2
3 4
Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).
In tables 1 and 2, the input (1) produces the correct output (-1).
So we have to determine which table agrees 100% with the system of equations given.
Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.
First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).
Thus, table 1 correct represents the solution of the system of equations.
Step-by-step explanation:
x is greater than or equal to 10.
x ≤ 10 and x < 10 options are incorrect, x is not less than 10.
x > 10 is incorrect, x can be greater but x can be equal to 10 as well.
X ≥ 10 is correct. x is greater than or equal to 10.
<u>Key:</u>
> - Greater Than.
< - Less Than.
≥ - Greater Than or Equal to.
≤ - Less Than or Equal to.
The answer would be 50 divided into 360 and then divide to find your answer and you can explain by saying how you divided to get your total
Answer:
Yes, the cost 
in dollars and the amount of yogurt 
are proportional.
The equation is: 
Step-by-step explanation:
1. If varies directly as , you can write it as following:
Where 
is the constant of proportionality.
2. Let's calculate the value of the constant of proportionality. If 
and 
, you have:
3. Then, the equation is:
4. Let's verify if they are directly proportional. Substitute 
which is the amount of yogurt bought by Jonah. The result must be $0,48:
5. They are directly proportional.
