One equation in a system of equations is y=4x-5 write a second equation to complete the system if the solution to the system is (3,7) PLSSS BE QUICK :))
Answer:
4y = -x + 31
Step-by-step explanation:
Given that one equation in a system of equations is y = 4x - 5 write a second equation to complete the system if the solution to the system is (3,7)
Since the solution of the system is (3, 7), that means the two lines of equations meet or intersect at point X = 3 and Y = 7
Let assume that the two equations are perpendicular to each other. Then, there slope can be expressed as
M1M2 = -1
Where M1 = 4
Find M2
4M2 = -1
M2 = -1 / 4
Using general linear equation
Y = MX + C
Let's find C by substituting Y, X and M2
7 = -1 /4( 3 ) + C
7 = -3/4 + C
C = 7 + 3/4
C = 31/4
Substitute C back into the equation
Y = -1/4X + 31/4
4y = -x + 31
Therefore, the second equation is
4y = -x + 31

Carmen reads 2/3 chapters in 7/8 hours. What is the unit rate in chapters per hour?
Write your answer in simplest form.
Answer:
16/21
Step-by-step explanation:
Divide both sides by 7 to get 1/8
2/3 = 7/8
1/7 x 2/3 = 7/8 x 1/7
2/21 = 1/8
Then multiply both sides by 8 to get 8/8 which is 1
8/1 x 2/21 = 1/8 x 8/1
16/21 = 1
The estimated world population in the year 1650 was 550,000,000. The estimated
world population in 1750 was 725,000,000. By how many people did the world's
population increase between 1650 and 1750?
Answer:
175,000,000
Step-by-step explanation:
you subtract 550,000,000 from 725,000,000
The population of New York state can be modeled by:
P(t) = 19.71/(1+61.22e^(-0.03513t))
Where P is the population in millions and t is the number of years since 1800. What is New York's maximum sustainable population?
Answer:
The answer is "19.71 million".
Step-by-step explanation:
[tex]\to P(t) = \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]
where
[tex]\to p= \text{population in million} \\\\\to t= \text{time in years}\\[/tex]
when t is increases, then [tex]61.22 \ e^{-0.035 t}=\frac{61.22}{e^{0.035t}}[/tex] when decrease so that p(t) continually grows in size to reach the optimum population which you find if t is quite high [tex]t \to \infty[/tex]
[tex]\to P_{max} = \lim_{ \ t \to \infty} \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]
[tex]when \ t \to \infty \ , 0.035 t \to \infty \ , e^{(0.03513t)} \to e^{\infty} \to \infty\ \ e^{\frac{1}{0.035t} = \ e^{-0.035t}} \to 0[/tex]
[tex]= \frac{19.71}{1+0}\\\\= \frac{19.71}{1}\\\\ = 19.71 \ million[/tex]

Simon has a farm and has to buy a certain amount of feed for each animal. He buys feed once a month and counts all of his animals to see how much feed he needs to buy. Chicken feed is about $0.5 per chicken, each horse eats about $5 worth of feed, and goats eat about $4 worth of feed. What equation should he use to find how much he should spend on feed?
A. 0.50 +5h + 4g = total spent on feed
B. 9.5a = total spent on feed
C. 0.50 +5h + 40 = 100
D. 0.59 +49 +5g = total spent on feed
Answer:
A

Answer: x < 100 , where x = the temperature of a pot of water ( in degrees Celsius).
Step-by-step explanation:
The boiling point of water is 100 degrees Celsius.
The temperature of water that is not boiling must be less than 100 degrees Celsius.
Let x be the temperature of a pot of water ( in degrees Celsius).
Then, as per given,
x < 100
hence, the inequality to represent a pot of water that is not boiling.:
x < 100

I need help on how to solve 8 × 6 + (12 - 4) ÷ 2
Answer:
42Step-by-step explanation:
8x6+(8)/2
48+4
42
Answer:
52
Step-by-step explanation:
So in order to answer this question we are going to have to use the order of operations by starting with the parenthesis of subtracting 4 from 12:
8 × 6 + (12 - 4) ÷ 2
12 - 4 = 8
Now the equation looks like this:
8 × 6 + 8 ÷ 2
Now we multiply 8 by 6 and dividing 8 by 2 because multiplication and division come first:
8 * 6 = 48
8/2 = 4
So the equation looks like this:
48 + 4
We now add them together to get our answer:
48 + 4 = 52
So the answer to this equation is 8 × 6 + (12 - 4) ÷ 2 = 52
Hope this helps you
Here is a rectangle ABCD.
A
B
20 cm
D
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
answer
15.5%
Step-by-step explanation:
length = 30
30+10%=33
breadth=20
20+5%=21
area of rectangle = length × breadth
600² centimeters = 30 × 20
693² centimeters = 33 × 21
Increase = 15.5%

a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km
Answer:
7 hours and 30 minutes
Step-by-step explanation:
[tex]240 \div 4 = 60km \: per \: h[/tex]
[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]
It will take motor bike 7.5 hours to cover 450 Km of distance.
What is Speed in Kinematics?Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.
Mathematically-
S = Δd/Δt or S = {d(2) - d(1)}/{t(2) - t(1)}
It is a scalar quantity as it only has magnitude and no direction.
Given is a motor bike travels 240 km ins 4 hours.
We can calculate the speed of the bike as -
s = 240/4 = 60 Km/hr
Then, the time taken to cover 450 Km will be -
t = 450/60
t = 7.5 hours
Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.
