Answer:
no solutions
Step-by-step explanation:
-4x-4=-4(x+2)
Distribute the negative
-4x-4 = -4x-8
Add 4x to each side
-4x+4x-4 = -4x+4x-8
-4 = -8
Since this is not true there are no solutions
Answer:
This fraction is in the simplest form already.
Step-by-step explanation:
This fraction is in the simplest form already. Here is why.
Result in decimals: 0.78
If the population decreases by 2% each year, that can be represented by multiplying the population by 0.98 mathematically. So if it decreases by 2% each year, an equation we can use is:
P*(0.98)^t,
where P is the current population and t is the number of years.
So in 2020, that would be 10 years from now, so the population would be:
1759*(0.98)^10 = 1437.23
Or about 1437 people.
How long till it is less than 1000? We can set up an inequality and solve:
1759*(0.98)^t < 1000
(0.98)^t < 1000/1759
t*ln(0.98) < ln(1000/1759)
t > ln(1000/1759)/(ln(0.98)) (swap the sign because ln(0.98) is a negative #)
t > 27.95
So the population would be below 1000 in about 28 years, or 2038.

Answer: 35 feet</h3>
Work Shown:
1 inch : 7 feet
5*(1 inch) : 5*(7 feet)
5 inches : 35 feet
5 inches on paper correspond to 35 feet in the actual house.
Answer:
y = 10 + 2.50h
$25
Step-by-step explanation:
first the equation is written as such because she pays $10 no matter how many hours she rides. She also pays 2.50 for each hour so use h as the variable to define number of hours she rides the bike.
since equation is y = 10 +2.50h
and h = 6 hours, substitute and find the total cost
y = 10 + 2.50(6)
= 10 + 15
= $25
