i could be wrong but i did it in my head , but the equation is right . just do that in order
Answer:
( 0.5, - 1 )
Step-by-step explanation:
So here is the equation:
x2 + x1 / 2 For the x coordinate
y2 + y1 / 2 For the y coordinate
x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.
Thus:
4 + -3 / 2 = 0.5 x coordinate
2 + -4 / 2 = -1 y coordinate
So it becomes (0.5, -1)

Write each decimal number as a fraction or mixed number in simplest form?
You're letting x = 0.325325325…, which means
1000x = 325.325325325… (or 325.325, but pretend the underline is actually an overline)
Then the next box you'd fill in with 0.325325325… (or 0.325).
Subtracting these, you have
1000x - x = 325.325325325… - 0.325325325…
999x = 325
Finally, solving for x gives
x = 325/999
Write the equation of the line in slope intercept form that passes through the point (6,-2) and is parallel to the line y = -3x + 5.
Answer:
For a line to be parallel it must have the same slope. So the slope of the new equation is 6.
The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....
-5=6(3)+b
Solve for b (the y-intercept)
b= -23
Therefore.... y=6x-23
??? does that help????
solve the equation simultaneously:
y = 2-2x
y = -16 + 2(x-3)^2
Answer:
y = -26
Step-by-step explanation:
[y = 2 - 2x] + [y = -16 + 2(x - 3)^2]
y = -16 + 2x - 6^2
y = -16 + 2x - 6^2 + 2 - 2x
y = (+2x - 2x) - 16 - 6^2 + 2
y = -16 - 6^2 + 2
y = -16 - 12 + 2
y = - 28 + 2
y = -26

What is the domain and range of this graph?
Answer:
Domain: [-5, 5)
Range: (1, 3]
Brackets and parenthesis are important! Make sure to put them in the correct spot
Step-by-step explanation:
Domain is which x values the line hits. It hits from -5 to 5 but doesn't include 5 as indicated by the open circle.
Range is which y values the line hits. It hits from 1 to 3 but doesn't include 1 because, again, there is an open circle.
When a number is not included, you put it with a parenthesis.
When it is included, you put it with a bracket.
Please help ASAP and explain the answer, thank you
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11
A scientist is studying some rabbits. A disease is killing the rabbits. A population of 240 of these rabbits was reduced to 180 rabbits in two days. The rabbit population is decreasing exponentially. Work out how many of the 240 rabbits will still be alive at the end of 7 days (5 marks)
Here we have a problem with exponential decays, we will find that we can expect that 110 rabbits will still be alive at the end of 7 days.
An exponential decay can be written:
P(x) = A*e^(-k*x)
Where:
A is the initial amount.
k defines the rate of decrease.
x is our variable.
In this case, the exponential decay is applied to the population of rabbits, and we know that:
The initial population is 240, then A = 240
P(x) = 240*e^(-k*x)
We also know that after two days (at x = 2) the population was 180, then we can write:
P(2) = 180 = 240*e^(-k*2)
With this equation we can find the value of k:
180 = 240*e^(-k*2)
180/240 = e^(-k*2)
Now remember that:
Ln(e^n) = n
then if we apply the natural logarithm to both sides, we get:
Ln(180/240) = Ln(e^(-k*2)) = -k*2
-Ln(180/240)/2 = k = 0.144
Then the equation is:
P(x) = 240*e^(-0.144*x)
Now with this, we can find the population of rabbits after 7 days, we just need to evaluate the above function at x = 7, we will get:
P(7) = 240*e^(-0.144*7) = 110.3
That we could round down to the next whole number, 110.
Concluding, we can expect that 110 rabbits will still be alive at the end of 7 days.

Name the plane that is highlighted in the diagram below.
We want to define the name of a plane. We will find that some of the possible names are:
IJF, JFE, FEI.
To define any given plane, we can just use two collinear points that are on the plane and a third point, which is on the plane and is not-collinear to the other two points.
Remember that points are collinear if we can connect them with a line.
So for the shown plane, some names can be:
IJF
where IJ are two collinear points and F is the third point that is non-collinear to the other two and also is on the plane.
Other names can be:
JFE
FEI
etc.

Hi how can I graph this if it dosn't have a slope?
1. y = (2/3)x - 1
y = -x + 4
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3
