solve for k 6=2-k for math :) i needa hurry and get it done
Answer:
-4 is the correct ans
hope it helps
Step-by-step explanation:
[tex] \tt{6 = 2 - k}[/tex]
~Swap the sides of the equation
⟶ [tex] \tt{2 - k = 6}[/tex]
~Transpose 2 to right hand side and change it's sign
⟶ [tex] \sf{ - k = 6 - 2}[/tex]
~Subtract 2 from 6
⟶ [tex] \tt{ - k = 4} [/tex]
~Divide both sides of the equation by -1
⟶ [tex] \tt{ \frac{ - k}{ - 1} = \frac{4}{ - 1}} [/tex]
⟶ [tex] \tt{k = - 4}[/tex]

Step-by-step explanation:
The algebraic expression is
(x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)
The options are Arrangement
a.(x+5/x+2) * ( x+2/x+5) Number 2

Factorizing the expressions (x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)
=(x²+ 5x+2x+ 10/ x²+ 2x+2x+4 ) (x²+ 2x+x+ 2/x²+ 5x+x+5)
Taking common
=[x(x+5) +2(x+5)/ x(x+2) +2(x+2) ] [ x(x+2) +1(x+2)/ x((x+5) +1(x+5)]
Putting commons together
=[(x+2) (x+5)/ (x+2) (x+2)] [ (x+2)(x+1)/ (x+1) (x+5)]
Cancelling
= [ (x+5)/ (x+2)]* [ (x+2)/ (x+5)]
=[ (x+5)/ (x+2)] [ (x+2)/ (x+5)]
Again Cancelling
=1
The above question is solved in 4 steps :
Step 1
(x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)
Step 2
(x+5/x+2) * ( x+2/x+5)
Step 3
(x+5/x+2) ( x+2/x+5)
Step 4
1 which is the answer .
The steps
(x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2) ,
(x+5) ( x+2) /(x+5),
(x+7/x+4) ( x+1/x+2) and (x+2) are not related to this question.

What is the distance between A and B?
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving the given problem using the distance formula.
Problem: What is the distance between A(-3, -4) and B(4, 5)?
From inspection on the given problem:
[tex]\sf (x_1, y_1) = (-3, -4)[/tex][tex]\sf (x_2, y_2) = (4, 5)[/tex]Substitute the given values into the distance formula and solve for AB:
[tex]\sf AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf AB = \sqrt{[4 - (-3)]^2 + [5 - (-4)]^2}[/tex][tex]\sf AB = \sqrt{(7)^2 + (9)^2}[/tex][tex]\sf AB = \sqrt{49 + 81}[/tex][tex]\bold{AB = \sqrt{130} \approx 11.4 \: units}[/tex]Therefore, the distance between two points is [tex]\sqrt{130}[/tex] or 11.4 units.

SOLVE FOR Y, WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
1. As you can see in the picture, x is 116 degrees, because that angle and the angle labeled 116 degrees are corresponding, meaning that their angles are the same.
2. As you can also see in the picture, y+11+x = 180 deg, because they are two angles that make a straight angle. We know that x is 116 deg, so we can solve y with an equation:
y + 11 + 116 = 180
y + 127 = 180
y = 180 - 127
y = 53 degrees.
Hope this helped! Don't forget to mark it Brainliest!
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been folling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
Answer:
Step-by-step explanation:
This question is incomplete; here is the complete question.
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
If it continues to fall at this rate, what will the temperature be:
In 2 hours ............. In 5 hours .............. In half an hour......................
If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.
Then after 'x' hours, temperature on the top of the mountain will be represented by the function,
T(x) = 0 - 3x
Therefore, temperature after 2 hours = -3(2) = -6°C
Temperature after 5 hours = -3(5) = -15°C
Temperature after half an hour = [tex]-3(\frac{1}{2})[/tex]
= -1.5°C

If a snowball melts so that its surface area decreases at a rate of 7 cm2/min, find the rate at which the diameter decreases when the diameter is 8 cm. cm/min
Answer:
7/16π
Step-by-step explanation:
The surface area of the snow ball = 4πr^2
Let the surface area= y
Then y= 4πr^2
The derivative can be taken with respect to time as
dy/dt= (8πr)dr/dt...........eqn(1)
We were told that its surface area decreases at a rate of 7 cm2/min.
Then dy/dt=-7
diameter = 8 cm. cm/min, the radius r= 4cm/min
r= 4
Substitute the values of r into eqn(1)
dy/dt=(8π×4)dr/dt
-7=(32π) dr/dr
dr/dt= -7/32π................eqn(**)
But we know that diameter d= 2× radius
d=2r............eqn(*)
We can find the derivatives with respect to t as
dd/dt=2dr/dt
Then substitute en(**) we have
dd/dt=2(7/32π)
dd/dt= -14/32π
Divide both numerator and denominator by 2
dd/dt= -7/16π
Hence, the diameter decreases by the rate of 7/16π

High school text books don't last forever. The lifespan of all high school statistics textbooks is approximately
normally distributed with a mean of 9 years and a standard deviation of 2.5 years. What percentage of the
books last more than 10 years?
34.5%
84.5%
O O O O O
65.5%
11.5%
69%
Answer:
34.5%
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 9, \sigma = 2.5[/tex]
What percentage of the books last more than 10 years?
As a proportion, this is 1 subtracted by the pvalue of Z when X = 10. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{10 - 9}{2.5}[/tex]
[tex]Z = 0.4[/tex]
[tex]Z = 0.4[/tex] has a pvalue of 0.655
1 - 0.655 = 0.345
So
34.5% of the books last more than 10 years.

Each unit in the graph above is one mile. How far would you have to drive from the art gallery to the dry cleaners and then continue on to the theater?
A) 12 miles
B) 11 miles
C) 10 miles
D) 5 miles
Answer:
Option C i.e. 10 miles is true.
Step-by-step explanation:
From the graph, it is clear that:
The art gallery is located at x = 7 and y = 2
The dry cleaners is located at x = 7 and y = 7
The theater is located at x = 2 and y = 7
Given that each unit is 1 mile.
Distance from the art gallery to dry cleaners is on the vertical path.
so
Distance from art gallery to dry cleaners = 7 - 2 = 5 miles
As Theater and dry cleaners are on the horizontal path.
Thus, in order to move to the theater from dry cleaners, all we need is to count the unit on the x-axis from x = 7 to x = 2.
i.e. 7 - 2 = 5 miles
Thus, the total distance: 5 + 5 = 10 miles
Therefore, option C i.e. 10 miles is true.

Determine the value of y, if x is –10.
y = |x| – 11
Answer:
y = -1
Step-by-step explanation:
The two lines around x is the absolute value symbol. Absolute value is how far away a number is from 0 on a number line. -10 is 10 points away from 0, so it is now 10.
y = 10 - 11
y = -1
