Answer:
y = 2x + 2
Step-by-step explanation:
y = mx+c
m = slope
c =y -intercept
Therefore, the required equation is:
y = 2x + c
Putting the point (0,4) in it as it lies on a line, we get:
4 = 2 + c
Therefore:
c = 2
So, y = 2x + 2
Brainlist pls!
The equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4
Equation of a lineThe equation of a line in point-slope form is expressed as:
y = y1 = m(x-x1)
Given the following
Slope m = 2
(x1, y1) = (0, 4)
Substitute
y - 4 = 2(x- 0)
y -4 = 2x
y = 2x + 4
Hence the equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4

Suppose f(x)=x^2 what is the graph of g(x)=f(2x)
i have seen other descriptions saying that you should substitute 2x into the equation, but where does that 2x come from and what is next?
Answer:
Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):
g(x) = f(2x) = (2x)² = 4x²
Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:

Two boats sail from A. One boat sails to B, and the other boat sails to C.
BAC = 115c
The bearing of B from A is 200c.
Find the bearing of A from C.
Answer:
265°
Step-by-step explanation:
I think we have to minus 200 - 115 = 85
then plus them with 85 and 95 so
85 + 85+ 95 = 265°C

Five friends want to travel on a trip. The bus ticket price is $50 for each friend, and the rooms and meals for everyone will cost $850.
To pay for the trip, friends work in the local shop. Each of them is paid $5 per hour. If each friend works the same number of hours, how many hours must each friend work so that there will be enough money to pay for the entire cost of the trip?
Answer this pls I'm this accounts cousin help me
Answer:
Step-by-step explanation:
Okay so first you need to find out how much money it will cost in total.
$50*5
=$250
$250+$850=
$1,100
Now, $1,100 divided by 5
1,100/5
=220 hours
And there are 5 friends so divide the total amount hours by 5.
220/5
=44 hours
So you see, each friend will need to work 44 hours.
I hope this helped :)

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer to the nearest hundredth
Answer:
(0, 4.5)
Step-by-step explanation:
*The equation can be put into Desmos, to find the point, but the work to prove it is here*
f(x)=c/1+Ae^-Bx
Y=C
C=18 A=3 -B=-0.1
*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*
f(0)=18/1+3e^-o.1(0)
= 18/1+3e^0
=18/1+3(1)
=18/1+3
=18/4
=4.5
x=0 y=4.5
Maximum growth rate = (x,y) --> (0, 4.5)

The expression showing the number of students in the drama club the next year is 15+d.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, there are 20 students in a drama club,
5 of them will leave in next year, and d students will join,
We are asked to construct an expression to represent the total number of students in the drama club next year.
So, the present number of students in the club = 20
After next year = 20-5 = 15
After the joining = 15+d
Hence the expression showing the number of students in the drama club the next year is 15+d.

aschool charges $6 per ticket to a dance they spend $300 on music and decerations the expretion 6n-300 describes the amount of profit the school makes from the dance if n students buy tickets what does 6n represent in this context
Answer:
$6n will represent the total revenue made from selling n tickets at $6 per ticket
Step-by-step explanation:
Here, we want to get what 6n means in the given context
Mathematically when calculating profit, we have to subtract the cost from the revenue
The revenue refers to the money made ;
From the question, $6 tickets were sold to a total of n people
The money made from these sales will be the product of the cost of each ticket by the number of people who bought the ticket
That will be $6 * n = $6n

A. -9/2
B. 1
C. 9/4
D. 5/2
Answer:
9/4
Step-by-step explanation:
2(x - 10) + 4 = -6x + 2
2x - 20 + 4 = -6x + 2
2x - 16 = -6x + 2
8x - 16 = 2
8x = 18
x = 18/8 or 9/4

A bag holds 4 red marbles, 3 green marbles, 2 yellow marbles, and 1 blue marble. You pull one out without looking. What is the probability that you pull a marble that is not green?
Answer:
the probability of pulling a marble that is not green is 7/10
Answer:
- 7 / 10
- 70%
Step-by-step explanation:
4 red + 3 green + 2 yellow + 1 blue = 10 marbles
If you remove green marbles:
4 red + 2 yellow + 1 blue = 7 marbles
So the probability of not pulling a green marble is 7 out of 10.

Hello There!
So the sum of the cakes (y) and cookies (x) is 64
so x + y = 64
It says that the amount of cookies he sold was 4 less then 3 times the number of cakes he sold
x = cookies
y = cakes
he sold 3 times the amount of cakes (y) - 4
so x=3y-4
So we can conclude that the answer would be D

1. Look at the following correlation scatter plot. What type of a correlation is it?
a. Negative correlation
b. Positive correlation
c. Zero correlation
d. All of the above
Scatter plot is missing, so i have attached it.
Answer:
C : zero correlation
Step-by-step explanation:
A correlation is said to be negative between two variables when they are related in such a manner that when one variable increases, the other variable decreases and vice versa.
However, a correlation is said to be Positive when one variable increases as the other increases as well and vice versa which means they both move in the same direction.
However, in the image of the scatter plot attached, we see that it is neither positive or negative correlation as there is no clear visible relationship between the variables on the x and y axis.
Thus, we can say there is zero correlation.

Answer:
16.5 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 13² = 21²
x² + 169 = 441 ( subtract 169 from both sides )
x² = 272 ( take the square root of both sides )
x = [tex]\sqrt{272}[/tex] ≈ 16.5 cm ( to the nearest tenth )
