Cy +y=d - 4
y(c+1)=d-4
y=d-4/c+1
Answer:
3.2 ft
Step-by-step explanation:
The initial distance from the base of the ladder to the wall is:
After moving the ladder, the distance from the base to the wall is 12 - 2x while the height of the ladder is 16 + x. The distance x is given by:
Therefore, the top of the ladder is 3.2 ft higher now.
Answer:
All of the points lie on the graph except for the coordinates (-2,1) and (1,5)
Step-by-step explanation:
Answer:2
Explanation:
The statement is expressed as
y
∝
1
x
inverse means
1
variable
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
⇒
y
=
k
x
To find k use the given condition that y = 8 when x = 4
8
=
k
4
⇒
k
=
4

8
=
