Find the coordinates of the midpoint of if J (-9,-5) and K (21,-7).
Answer:
(6,-6)
Step-by-step explanation:
[tex]Midpoint = \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-9,\:-5\right),\:\\\left(x_2,\:y_2\right)=\left(21,\:-7\right)\\\\=\left(\frac{21-9}{2},\:\frac{-7-5}{2}\right)\\\\=(\frac{12}{2} , \frac{-12}{2})\\ \\=\left(6,\:-6\right)[/tex]
Answer:
(6, -1)
Step-by-step explanation:
P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2)
We have that px=−9, py=5, qx=21, qy=−7.
Thus, M=(−9+212,5−72)=(6,−1).

What is the equation of a line that passes through (1,2) and is perpendicular to the given line?
The given line passes through (0,10) and (2,0), so its slope is
[tex]\frac{10-0}{0-2}=-5[/tex]
Since perpendicular lines have negative reciprocal slopes, the slope of the line we want to find is 1/5.
Substituting into point-slope form,
[tex]y-2=\frac{1}{5}(x-1)\\\\y-2=\frac{1}{5}x-\frac{1}{5}\\\\\boxed{y=\frac{1}{5}x+\frac{9}{5}}[/tex]
A researcher was studying how the weights of horseshoe crabs along the East Coast vary between northern and southern habitats. In spring 2006, during breeding season, the researcher randomly selected 50 horseshoe crabs in southern habitats. In fall 2006, before the breeding season began, the researcher randomly selected 50 horseshoe crabs from northern habitats. It was found that crabs in southern habitats weighed more, so the researcher claimed that location had an effect on the weight of horseshoe crabs.
The response variable in this experiment is:_______.
A, the different habitat locations.
B. the crabs
C. the season each sample was taken.
D. the weight of the crab
Answer:
Option D (the weight of crab) would be the correct choice.
Step-by-step explanation:
In mathematics, the sum being analyzed depending on a variety of parameters, which have been calculated as explanatory variables, has become a response variable. It is analogous with the utilization of the definition of variables of the study. A variable with an order to respond is categorized as either a dependent variable.Some other preferences are not connected with the sustaining. So choice D is the right one.

If a big of pretzels is 10.5 pounds and it cost $0.18 per pound what would I use to solve +,-,x or division ???n
You use multiplication
1 pound = 0.18 dollars
10.5*(1 pound) = 10.5*(0.18 dollars) .... multiply both sides by 10.5
10.5 pounds = (10.5*0.18) dollars
10.5 pounds = 1.89 dollars
So in short you simply multiply 10.5 and 0.18 to get 1.89 dollars as the final answer

What is the slope of the line represented by the equation
3
x
+
4
y
=
8
?
Answer:
The slope is -3/4
Step-by-step explanation:
3x+4y = 8
We want to get the equation in slope intercept form
y = mx+b where m is the slope
Subtract 3x from each side
3x+4y-3x= -3x+8
4y = -3x+8
Divide by 4
4y/4 = -3x/4 +8/4
y = -3/4x +2
The slope is -3/4 and the y intercept is 2

Solve the following equation for y. 6x - 3y = 18
Answer:
Y=-6+2x
Step-by-step explanation:
So Since the tivne equation is 6x-3y=18, Isolate y Because we’re finding the variable y not x
So First subtract 6x on both sides (it doesn’t have to be the same number when subtracting like what they taught you in middle school, but you can’t combine those two since their different terms)
-3y=18-6x
Now divide -3 on both sodes to isolate Y
y=18-6x/-3
Simplify
y=-6+2x
If it’s not then i would need x the variable.
If one container of applesauce contains 3/3-4 ounces, how much applesauce is in a 6-pack of applesauce
The total volume of applesauce in a 6-pack is (22 + 1/2) ounces.
How much applesauce is in a 6-pack of applesauce?We know that a single cotainer of apple sauce contains 3 + 3/4 ounces of applesauce.
Now, a 6-pack of applesauce has 6 containesr on it, then the total volume of applesauce will be 6 times the volume that we have above, so what we need to solve here is the following product:
Volume = 6*(3 + 3/4) oz = (6*3 + 6*3/4) oz
We can simplify that to:
(18 + 18/4) oz
And rewrite the fraction as: 18/4 + 16/4 + 2/4 = 4 + 1/2
Then the total volume is:
(18 + 4 + 1/2) ounces = (22 + 1/2) ounces.

Sketch a graph of a quadratic function with imaginary roots.
Answer:
A quadratic function with imaginary roots will never intersect the x-axis, because imaginary numbers are not real numbers. Therefore, the graph of a quadratic function with imaginary roots will be a parabola that does not touch the x-axis.
Here is an example of a quadratic function with imaginary roots:
f(x) = x^2 + 2x + 5
The discriminant of this quadratic equation is b^2 - 4ac = 4^2 - 4 * 1 * 5 = -4. Because the discriminant is negative, the roots of the equation are imaginary.
The graph of this function is shown below: Attachment
As you can see, the graph does not intersect the x-axis. This is because the roots of the equation are imaginary, and imaginary numbers do not exist on the real number line.

Next, you will subtract the exponents.
8 minus 3 is 5 so it is incorrect. The correct answer is 9.6 × 10^5 not 9.6 × 10^-5.

5) On Monday, 411 students went on a trip to the zoo. All 9
buses were filled and 6 students had to travel in cars. How many students were

Answer:
There were 45 students in each bus
Step-by-step explanation:
Arithmetic
One can be in situations where different mathematic operations must be performed in order to find a result. Four operations are known as basics in arithmetic: addition, subtraction, multiplication, and division. Some basic logic is also needed on certain problems to decide what operations are adequate.
We know 411 students went on a trip to the zoo. There were 9 buses filled but 6 students didn't fit, so they had to travel in cars. This information tells us that 411 - 6 = 405 students went on the buses.
Since there were 9 buses, it means that each bus had 405 / 9 = 45 students.
There were 45 students in each bus
