Answer:
y=2x+2
Step-by-step explanation:
the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2

(1 point) A fish tank initially contains 15 liters of pure water. Brine of constant, but unknown, concentration of salt is flowing in at 5 liters per minute. The solution is mixed well and drained at 5 liters per minute. a. Let x be the amount of salt, in grams, in the fish tank after t minutes have elapsed. Find a formula for the rate of change in the amount of salt, dx/dt, in terms of the amount of salt in the solution x and the unknown concentration of incoming brine c. dx grams/minute b. Find a formula for the amount of salt, in grams, after t minutes have elapsed. Your answer should be in terms of c and t. x(t)= grams c. In 10 minutes there are 25 grams of salt in the fish tank. What is the concentration of salt in the incoming brine? C = g/L
Answers
Answer:
a. [tex]\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c[/tex]
b. [tex]x(t) = 6\frac{2}{3} \cdot c \cdot t[/tex]
c. [tex]c = \dfrac{3}{8} \ g/L[/tex]
Step-by-step explanation:
a. The volume of water initially in the fish tank = 15 liters
The volume of brine added per minute = 5 liters per minute
The rate at which the mixture is drained = 5 liters per minute
The amount of salt in the fish tank after t minutes = x
Where the volume of water with x grams of salt = 15 liters
dx = (5·c - 5·c/3)×dt = 20/3·c = [tex]6\frac{2}{3} \cdot c \cdot dt[/tex]
[tex]\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c[/tex]
b. The amount of salt, x after t minutes is given by the relation
[tex]\dfrac{dx}{dt} = 6\frac{2}{3} \cdot c[/tex]
[tex]dx = 6\frac{2}{3} \cdot c \cdot dt[/tex]
[tex]x(t) = \int\limits \, dx = \int\limits \left ( 6\frac{2}{3} \cdot c \right) \cdot dt[/tex]
[tex]x(t) = 6\frac{2}{3} \cdot c \cdot t[/tex]
c. Given that in 10 minutes, the amount of salt in the tank = 25 grams, and the volume is 15 liters, we have;
[tex]x(10) = 25 \ grams(15 \ in \ liters) = 6\frac{2}{3} \times c \times 10[/tex]
[tex]6\frac{2}{3} \times c =\dfrac{25 \ grams }{10}[/tex]
[tex]c =\dfrac{25 \ g/L }{10 \times 6\frac{2}{3} } = \dfrac{25 \ g/L}{10 \times \dfrac{20}{3} } =\dfrac{3}{200} \times 25 \ g/L= \dfrac{75}{200} \ g/L = \dfrac{3}{8} \ g/L[/tex]
[tex]c = \dfrac{3}{8} \ g/L[/tex]

Deshaun rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 84 cents for each mile driven. Deshaun had to pay $237.03 when he returned the truck. For how many miles did he drive the truck?
Answers
Subtract the rental fee from the total:
237.03 - 16.95 = 220.08
Now divide the remainder by the charge per mile:
220.08 / 0.84 = 262
He drove 262 miles.

Answers
Answer:
1.2 × 10^6 hours
Step-by-step explanation:
Given the following :
equation relating the distance traveled in miles, d, to the number of hours flying, t ;
t=1500d
How long will it take the airplane to travel 800 miles
Here, d = 800 miles
Hence,
t = 1500(800) = 1,200,000 hours
t = 1.2 × 10^6 hours

This is my question for homework. "You and some friends took a metal detector to the beach every day for a week to search for coins. You managed to find 246 nickels, 312 dimes, and 204 quarters. When you divided them up, you realized that each person got the same exact amount of each coin with no coins remaining. How many are in your group? How many nickels did each person receive? How many dimes did each person receive? How many quarters did each person receive? " Thanks, Brainly your the best!!
Answers
Answer:
The data is:
Number of nickels = 246
Number of dimes = 312
Number of quarters = 204.
Now, in your group there are N people.
Dividing the coins into N people, you find that each one received the same amount of each type of coin. Then the quotient between each number of coins and N must be a whole number.
Now, you can see that the 3 numbers are even, so we know that N must be even.
For example, if N = 2, we could divide the 3 numbers of coins and get an integer in each case, but this is worded as "You and some friends" so N must be larger than 2.
Try with the next even integer:
N = 4.
nickels: 246/4 = 61.5
61.5 is not an integer: Then N can not be 4.
The next even number is N = 6.
nickels: 246/6 = 41
dimes: 312/6 = 52
quarters: 204/6 = 34
In each case we have integers, this means that 6 divides the 3 numbers of coins, so each person can receive the same amount of coins.
The we can conclude with:
There are 6 persons in the group.
Each person gets 41 nickels, 52 dimes and 34 quarters.

If the ambient temperature is 0 then the damage index would be 14. Then the correct option is D.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Sven investigates the amount of damage to the head gaskets on the trucks in his fleet and the damage index depends on the ambient temperature.
He develops the equation y = –23x + 14 to model the relationship.
where y be the damage index and x be the temperature.
At zero temperature, the damage index will be
y = –23 (0) + 14
y = 14
The damage index is 14.

Answers
Answer:

Step-by-step explanation:
In order to figure out which of the 4 is a function, you must perform the vertical line test for each. No vertical line should intersect the graph of the relation at more than one point. D is the only one that doesnt hit two points when performing the vertical line test.
Since there are unique outputs for every point of x-axis so it represents a fucntion. Hence option D is correct.
Use the concept of fucntion is defined as:
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
Since we know that in a fucntion,
For each element of the domain, there is only one output.
Therefore,
For Figure A:
There are two outputs for each value of the positive x-axis.
This is not a function.
For Figure B:
There are outputs for x = 3,
Hence this is also not a fucntion.
For Figure C:
For a circle, there are always two puts,
Hence, This is also not a fucntion.
Figure D:
W can see that for each value of x-axis, there is a unique output,
Hence this is a function. So option D is correct.
