Answer:

m = - 16/10

= - 1.6

Step-by-step explanation:

m2 + 8m

(the - 16 here is divided into 10 m's as you can see in m2 and 8m)

So, in order to find out what 1m is, you have to <em>divide</em> - 16 by 10, which gives you - 1.6

Good luck!

Joe's Plumbing and Mark's Plumbing have different ways of charging their customers. The function defined by J(t)=45t represents
puteri [66]

Answer:

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Step-by-step explanation:

Let

t ------> the number of hours

J(t) ---->the total amount in dollars that Joe's  Plumbing charges

M(t) ---->the total amount in dollars that Mark's  Plumbing charges

we know that

The linear equation in slope form is equal to

f(x)=mx+b

where

m is the slope or rate of the linear equation

b is the y-intercept (initial value)

In this problem we have

<em>Joe's  Plumbing</em>

J(t)=45t

The slope or rate is equal to

m=\$45\ per\ hour

b=\$0

Mark<em>'s  Plumbing</em>

M(t)=40t+25

The slope or rate is equal to

m=\$40\ per\ hour

b=\$25

therefore

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)
