Answer:

The number of watches made is 8

Step-by-step explanation:

SO the equation is C=15n+85 where C is the total cost and N is the amount of watches

1)plug in C

385=15n+85

2)move 85 to the other side so it would become -85

385=15n+85 → 385-85=15n → 100=15n

3)divide 15 from both sides

100/15=15n/15 → 25/3=n

since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)

Answer:

(-1, 1/10) and (-2, 1/100)

I can't really explain because I just put it into my graphing calculator and clicked the trace button to find the y value at certain x values. A good website to do that on is Desmos

Solve 1/5 (x+3)=−(2x+3)

Rasek [7]

Answer:

Step-by-step explanation:

just simplify the LHS first.

You can either multiply 1/5 by (x+3) and then solve

multiply both sides by 5 to get rid of 1/5 on LHS

I will multiply by 5

(x+3)= -10x-15 ( 5*1/5(x+3)= -5(2x+3)

now rearrange the equation

x+3=-10x-15

-10x-15-x-3=0

-11x-17=0

-11x=17

x= -17/11
