Answer:
The answer is B.
Step-by-step explanation:
To obtain the inverse of a relation you simply interchange the x and y coordinates of each pair.
Here:
(3,1) becomes (1,3)
(3,1) becomes ((1,3)
(7, -7) becomes (-7,7) and
(12, -15) becomes (-15, 12)
Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
First you would need to find out how many beads are needed for the bracelets.
215 beads per bracelet x 6 bracelets = 1290 beads
This tells us that to make all 6 bracelets, it will use up 1290 beads, now subtract that from your total number of beads.
1500-1290= 210
So Zoe will have 210 beads left over. Since this is a word problem, it is best to answer it in the same format:
Zoe will use 1290 beads to make 6 friendship bracelets. After all of the bracelets are made, she will have 210 beads left over.
hope this helps!
It is 126 x=67 I hope this helps
(X+3)^2+(y-2)^2= 16
The formula is (x-h)^2+(y-k)^2=r^2
