Answer:

$slope = \frac{-15}{0}$ = Undefined

Step-by-step explanation:

To find the slope of these two points we use the slope formula

$slope = \frac{(y_{2} - y_{1})}{(x_{2}-x_{1})}$

$slope = \frac{((-8) - 7)}{((-5)-(-5))}$

$slope = \frac{-15}{0}$ The slope would be classified as undefined

Tommy can lay a brick walkway by himself in 12 hours. Robert does the same job in 10 hours.

Lapatulllka [165]

Answer:

5 5/11 hours

Step-by-step explanation:

So, there is a trick to doing this.

You would first need to get their work rate into the same measurements.

That's why we will find out how much they each work in one hour.

Tommy does 1/12 of the work in one hour while Robert does 1/10.

Here we can add them both up to make 11/60.

They finish 11/60 of the work in one hour.

They finish the job in 5 5/11 hours.

SOS if anyone could help that would be appreciated!!!❤️

Answer:

See below

Step-by-step explanation:

$2e)15-4x=10x+45$

Solve:

$15-4x=10x+45\\-4x-10x=45-15\\-14x=30\\ \boxed {x=-\dfrac{15}{7}}$ $3(x+1)=21$

Check:

$15-4 \left(-\dfrac{15}{7} \right)=10\left(-\dfrac{15}{7} \right)+45$

$15+\dfrac{60}{7} \right)=-\dfrac{150}{7} +45$

$\dfrac{210}{7} =30$

$30=30$

$3a) 3(x+1)=21$

Solve:

$3(x+1)=21\\3x+3=21\\3x=18\\x=6$

$3b) 2+3(x+1)=6x$

$2+3x+3=6x\\5=3x\\$

$x=\dfrac{5}{3}$

$3c) -2(2x-3)=-2$

Solve:

$-2(2x-3)=-2\\-4x+6=-2\\-4x=-8\\x=2$

Jason deposited $18 000 in a bank that offers an interest rate of 5% per annum compounded

8_murik_8 [283]

Answer:

$1995.97.

Step-by-step explanation:

Amount in bank after 20 days =

18000(1 + 0.05/365)^20

= $18049.38

So H = 18049.38 - 16093.41

= $1995.97.
