Step-by-step explanation:

The graph of the linear equation 3x + 5y
= 15 cuts the x-axis at the point ________.

Answers

Answer:

(0,5)

Step-by-step explanation:

3x-5y=15

Plug in 0 for y, because we are trying to find the value of x, when y is 0

so, 3x-5(0)=15

3x=15 Divide both sides by 3

x=5

so the answer in coordinate form is (0,5)

Gary bought a car for $40,000. If V = 40,000(.85)t represents the value of the car after t years, how long will it take the car to be worth less than one-fourth of its purchase price? A) 4 years B) 6 years C) 8 years D) 9 years

Answers

Answer:

D) 9 years.

Step-by-step explanation:

We have been given that Gary bought a car for $40,000 and equation $V=40,000(0.85)^t$ represents the value of the car after t years.

First of all we will find the one-fourth of 40,000.

$\text{One-forth of car's purchase price}=(\$40,000)/(4)$

$\text{One-forth of car's purchase price}=\$10,000$

To find the time it will take the car to be worth less than one-fourth of its purchase price, we will substitute V=10,000 in our given equation.

$10,000=40,000(0.85)^t$

Let us divide both sides of our equation by 40,000.

$(10,000)/(40,000)=(40,000(0.85)^t)/(40,000)$

$0.25=0.85^t$

Let us take natural log of both sides of our equation.

$ln(0.25)=ln(0.85^t)$

Using natural log property $ln(a^b)=b*ln(a)$ we will get,

$ln(0.25)=t*ln(0.85)$

$(ln(0.25))/(ln(0.85))=(t*ln(0.85))/(ln(0.85))$

$(-1.3862943611198906)/(-0.1625189294977749)=t$

$8.530048563597=t$

Upon rounding our answer to the nearest year we will get,

$t\approx 9$

Therefore, it will take 9 years the car to be worth less than one-fourth of its purchase price and option D is the correct choice.

Answers

first, convert so bottom numbers are the same

so find the smallest numbber that al of them will go into

10,6,5
first find th efactors
110=2 times 5
5=1 times 5
6=2 times 3

so the answer is 2 times 3 times 5=30

bottom number must by 30

1/10 times 3/3=3/30

2/6 times 5/5=10/30

3/5 times 6/6=18/30

6/10 times 2/2=18/30

least to greatest the order is 3,10,18

since3/5=6/10 they are equal so the order is

3/30,10/30,18/30,18/30 or

1/10,2/6,3/5,6/10 or since 3/5 and 6/10 is equivilent it is also
1/10,2/6,6/10.3/5

the common denominator is 30 so 1/10 would be 3/30 2/6 would be 10/30 3/5 would be 18/30 and 6/10 would be 18/30 in least to greatest it would be 1/10 2/6 6/10 and 3/5
