Answer:
Let s be the number of shorts and t be the number of T-shirts. s shorts cost $12s and t T-shirts cost $5t, then you have to find min and max value for the function f(s,t)=12s+5t.
The shaded domain (see image) is defined from the system of unequalities. The green lines are the graphs of function f(x,y) and it intersects domain in first point (0,5) (the minimum point) and in last point (20,0) (the maximum point). So,
.

Answer:
This is incorrect, the correct answer is 7/12
Step-by-step explanation:
Answer:
You're answer is right it is -2,2
Step-by-step explanation:
remember x comes before y
One way is factor
exg
if you wanted to find the square root of 36 you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6
so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81
the answer is a little more than 8
the more exact one would be from a calculator (8.0622577482985)
Answer:
$18.12
Step-by-step explanation:
A pound of raisins=$2
A pound of Almonds=$5.06
x= no. Of pounds of raisins
y=no. Of pounds of almonds
If six pounds of a trail mix contains 2 more pounds of raisins than almonds
Then,
x+y=6
x= 4 pounds
y= 2 pounds
Cost of 6 trail mix=4($2)+2($5.06)
=$8+$10.12
=$18.12
