Help me please show how you got the answer
Lilit [14]

Answer:

Firstly you need to put the equation in form of. y =ax+b

Let us do it

We have

2x-2y=18

-2y=18-2x

-y=(18) /2 - (2x)/2

-y =9-x

Mutiply by - to remove it beside y

Y=-9+x

Which is y=x-9

Slope =a=1

Yintercept=b=-9

Evaluate log12 - log4 + log5 and can you explain it to me?
mario62 [17]
Remember some simple log rules

log(a)+log(b)=log(ab)
and
log(a)-log(b)=log(\frac{a}{b})

work from left to right

log(12)-log(4)+log(5)=
log(\frac{12}{4})+log(5)=
log(3)+log(5)=
log(3*5)=
log(15)

A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. Use the formula r=(F/P)^1/n−1 to find the annual
enot [183]

Answer:

Step-by-step explanation:

The formula representing the the annual inflation rate r is expressed as

r = (F/P)1/n−1

Where

n represents the the number of years during which the value increases from P to F

A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. This means that

P = $800,000

F = $1,100,000

n = 6

Therefore,

r = (1100000/800000)1/6−1

r = 1.375/5 = 0.275
