4/x+9 = 9/x+5.... x= -61/5 or -12 1/5
try using the app Photomath, it’s really useful
I am not good at this so ii wont be able to solve it for ya but i can help you.
So to find the line of best fit you have to pick to pick to points on your scatter plot. Then with those two points you add the y points together then add the x points together. Your equation with be what you got in all y over x. That is your slope. I hope this helped you!
Answer:
Option B is correct that is the amount she is getting per bottle is $0.15
Step-by-step explanation:
We have been given the information that Melisande collected 14 bottles on Saturday and 9 bottles on Sunday
That means she has collected a total of 23 bottles
Let us assume that the amount she is paid for recycling is $b
Since she is left with $3.20 after the amount she gets for bottles we will get the equation below:
23b=3.20
Now, since she has to pay a one-time service fee equation will become
23b -0.25 =3.20
After simplification, we will get
23b=3.20+0.25=3.45
b=3.45/23=.15
b=$0.15
Therefore, The amount she is getting per bottle is $0.15
HOPE THIS HELPS :)
Answer:
a)7 cakes=£5.6
b)£2=4 drinks
c)£7.7
Step-by-step explanation:
a)5cakes=£4
1 cake=4/5=£0.8
7 cakes=£5.6
b)1 cake=3/6=£0.5
£2=4 drinks
c)(0.8×4)+(0.5×7)=£7.7
to find the radius of x^2+y^2-10x+6y+18=0, we must complete the square:
x^2 - 10x + y^2 + 6y = -18
Then:
x^2 - 10x + 5^2 - 5^2 + y^2 + 6y + 9 - 9 = -18
Collecting all three constants on the right-hand side, r^2 = -18 + 25 + 9 = 16
Then r = +sqrt(16) = +4 (answer)
