The given equation is in point-slope form.

The general form of an equation in point slope form is:

y- y_{1}=m(x- x_{1})

Here m is the slope and x_{1} and y_{1} are the coordinates of the point.

So in given equation the slope is 2/3, and the coordinates of point are (1,3)

Zinaida [17]
They both get their cars washed on every 60th day.


You can solve this equation by finding the lcm (least common multiple):

15 30 45 60 75 90 105

20 40 60 80 100

The lowest common multiple is 60 as it is the first multiple the two have in common.

So, in sixty days, they’ll both get their car washed again

laiz [17]

Given:

The two functions are:

g(b)=5b-9

h(b)=(b-1)^2

To find:

The value of (h\circ g)(-6).

Solution:

We have,

g(b)=5b-9

h(b)=(b-1)^2

We know that,

(h\circ g)(b)=h(g(b))

(h\circ g)(b)=h(5b-9)

(h\circ g)(b)=[(5b-9)-1]^2

(h\circ g)(b)=[5b-10]^2

Putting b=-6, we get

(h\circ g)(-6)=[5(-6)-10]^2

(h\circ g)(-6)=[-39-10]^2

(h\circ g)(-6)=[-49]^2

(h\circ g)(-6)=2401

Therefore, the value of (h\circ g)(-6) is 2401.
