Answer:
2nd quadrant
Step-by-step explanation:
https://en.wikipedia.org/wiki/Quadrant_(plane_geometry)
This is the concept of proportionality, given that z is directly proportional to x and inversely proportional to y then:
zαx/y
z=(kx)/y
where;
k is the constant of proportionality given by:
k=zy/x
but when x=3 and =6 then z=9.5
therefore:
k=(9.5*6)/3
k=19
hence the formula for z will be:
z=(19x)/y
the value of z when x=8 and y=12 will be:
z=(19*8)/12
z=12 2/3
7y+11+7y+11+7y+11=180(A.S.P)
21y+33=180
21y=180-33
21y=147
y=147/21
y=7
y=7
Answer:
7040
Step-by-step explanation:
first find how many are in 1 mile by doing 5280/3 to get 1760.
second multiply 1760x4 to get 7040
(5x^7y^2)(-4x^4y^5)=-20x^a y^b
<span>-20 x^11 y^7 = -20 x^a y^b </span>
<span>a = 11, b = 7 thus a: is you answer</span>
