Answer:
1st row 3 down
Step-by-step explanation:
A whole number<span> is one from the set containing zero and all of the positive </span>numbers<span>. A </span>negative number<span>, therefore, is not a </span>whole number<span>, but it is an integer. So the answer is false. </span>
Okay all you have to do is complete the square of the x and y's
so divide the coefficient of x by -2, then square it all and minus the square of the coefficient of x
hence (x-3)^2 - 9
then do the same for y
(y-4)^2 - 16
so (x+3)^2 + (y+4)^2 = 36
the radius is the root of the 36 so 6, and the centre is (-3,-4) because it's whatever would make the (x+3) or (y+4) equal to 0
Answer:
C(n)=1.25n
Where n= number of cans
Step-by-step explanation:
C=cost
n=number of cans
Quantity Total cost
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Total cost, c(n) =1.25n
Check
Total cost when n=4
Total cost c(4)=1.25×4
Total cost c(4)=5.00
