Answer:
No, it is not a function
Step-by-step explanation:
A function is where there is no two of the same domain.
The domain is the first coordinate.
Hope This Helps :)
The necklace chain costs $15, so subtract 15 from the total cost of $28.75.
28.75 - 15 = $13.75
Then, to find the amount of beads you divide the remaining amount by the cost of the beads.
13.75 ÷ 2.75 = 5
Therefore, you bought 5 beads.
<u>Answer : </u>
The value of r in (4,r),(r,2) so that the slope of the line containing them is is 7
<u>Solution: </u>
Slope of the line which is passes through
→ (1)
From question given that two points are (4, r), (r, 2). Hence we get
By substituting the values in equation (1),
→ (2)
Also given that slope that is m = , so on substituting the value of m in equation (2),
On simplifying,
-5r+20=6-3r
5r-3r=20-6
2r = 14
r =7
Hence value of r is 7.
Here
Length = x+3
Breadth = x
We know
Perimeter of reatangle = 2(l+b)
Or 34 = 2( x+3+x)
Or 17 = 2x+3
Or 14 =2x
Or x= 7
Therefore
Length = 10 and breadth = 7 cm
Thank you

I think its equal im not exactly sure so dont blame me if u get it worng :(
