Answer:
Slope= -5/8
y-intercept = -1/8
Step-by-step explanation:
ALWAYS make the equation "y=mx+c"
where m = slope/gradient and c = y-intercept
Now rearrange the equation:
5x+8y=-1
8y=-5x-1
y=-5x/8-1/8
Slope= -5/8
y-intercept = -1/8
Answer:
8000
Step-by-step explanation:
Answer:
Volume = 14,836.5 cubic inches
Step-by-step explanation:
Cylinder not shown but information given. So we will calculate the volume.
Volume of Cylinder is given by the formula:
Where
V is the volume
r is the radius (HALF of DIAMETER)
h is the height
It is given in the problem,
Height is 21
h = 21
and
half the diamter (aka radius) is 15
r = 15
Substituting into formula and using 3.14 for , we get the volume:
Hence, the volume is:
Volume = 14,836.5 cubic inches
When x varies inversely with y then you'll have
xα1/y
x=k/y where k is the proportionality constant
when x=8. y=10. k=?
8=k/10
make k the subject of the formula
k=10×8
k=80.
When x=6. y=?.k=80
6=80/y
Make y the subject of the formula
y=80/6
y=40/3
