Answer:
4y= -x - 28
Step-by-step explanation:
the products of the gradient of parallel lines is 1
m1 x m2=1.......(1)
8-4x=0
re-arranging we have
0=-4x +8
comparing with y=mx +c we have
m1=-4
put the value of m1 in eqn 1
-4 xm2 =1
m2 =-1\2
from the relation.....
m=y-y1\x-x1
put the value of m1 above
-1\2=y-(-9)\x-0
cross multiply
-1(x-8)=4(y+9)
-x +8=4y+36
re-arranging we have
4y=-x-36+8
4y=-x-28//

Answer:
h(x) = -6
Step-by-step explanation:
= x^3-5
= (-1)^3 - 5
= -1*-1*-1 - 5
= -1 - 5
= -6
Answer:
D = 9.4868
Step-by-step explanation:
The expression is the following
D = √((x2-x1)^2+(y2-y1)^2)
Where
(x1,y1) = (4,6)
(x2,y2) = (7,-3)
D = √((7-4)^2+(-3-6)^2)
D = √((3)^2+(-9)^2)
D = √(9+81)
D = √(90)
D = 9.4868
