It will be option 3 so the answer is 1 quarts
Answer:
B is the only solution
Step-by-step explanation:
These inequalities are shown in the attached picture. Which can be obtained drawing y > -2 (an horizontal line at y=-2, the region is above). and y<= 4-x, a line with a negative slope of -1 and intercept point of 4.
Any ordered pair, located inside the interception between these two regions is a solution of the system.
A. is Outside, below the horizontal line
B. is not clear by graph, hence, lets evaluate it in both inequalities
3>-2 (satisfies)
1+3<=4 (satisfies)
Hence B is a solution.
C. Is outside, we can evaluate it just to make sure:
5>-2 (satisfies)
1+5<= 4 (not true)
Hence C is not a solution.
D. is outside
Answer:
$1030
Step-by-step explanation:
Last winter:
Total expense = 370 * 2.56 = $947.2
Next year,
price increases 9% per gallon
which means, per gallon cost is $2.7904
Approx. expense = 370 * 2.7904 = $1032.448 which is round down to $1030
Answer:
−2x−3+4c+6z+7+3c
=−2x+−3+4c+6z+7+3c
Combine Like Terms:
=−2x+−3+4c+6z+7+3c
=(4c+3c)+(−2x)+(6z)+(−3+7)
=7c+−2x+6z+4
