Answer:

C. (x - 3)² = 1

Step-by-step explanation:

Given;

x² - 6x  + 8 = 0

Using completing the square method, the equation above is solved as follows;

x² - 6x  = - 8

Half the coefficient of 'x' (-6), square the result and add it to both sides of the equation;

Half of coefficient of x (-6) = ¹/₂ (-6)  = -3

x² + (-3)² = -8 + (-3)²

(x - 3)² = -8 + 9

(x - 3)² = 1

Thus, the correct option is 'C'

C. (x - 3)² = 1

Answer:

y=-1/2x-7

Step-by-step explanation:

y-y1=m(x-x1)

y-(-6)=-1/2(x-(-2))

y+6=-1/2(x+2)

y=-1/2x-2/2-6

y=-1/2x-1-6

y=-1/2x-7

Answer:

Option 3 (C)

Step-by-step explanation:

Given the scores of the students: 3, 4, 4, 5, 5, 6, 8, 10, 10, 12, 15, 18

To find the box plot that represents the data set, we need to find:

Min, Q1, median, Q3, and Max, which are all represented on a box plot.

Min = 3

Max = 18

Median = the average of the 6th and 7th data value = (6+8)/2 = 14/2 = 7

Q1 = the average of the 3rd and 4th data values = (4+5)/2 = 4.5

Q3 = the average of the 9th and 10th data values = (10+12)/2 = 11

The box plot that closely represented all these values is the box plot in option 3.

=3.75

Answer      $625:

Step-by-step explanation:

Since the discount is 24% that means that   $475 is 76% of the total

X is the 100% of the price (before sale)

475...............76%

x..........................100%

cross multiplication

76x  =  475x100

76x = 47500

Divide both sides by 76

x= 625

Answer:

31

Step-by-step explanation:

The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.

Answer and Step-by-step explanation:

We know that a is equal to 25.

Let's subtract that from the entire angle measure of line segment AB, which is 180.

180 - 25 = 155.

Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.

155 = 2x + 3x

155 = 5x

31 = x

So, the value of x is 31.

#teamtrees #PAW (Plant And Water)

Step-by-step explanation:

Hey there!

In (a) part we can see that a person delivers approximately 120 newspapers in 3 hours. Kate will deliver 30 × 3 = 90 newspapers. So, (a) part is the answer.

In (b) part, a person delivers 40 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers. So, Kate is faster, (b) option cancelled.

In (c) a person delivers 110 newspapers in 4.5 hours. Kate will deliver 30 × 4.5 = 135 papers, that's again greater. Option (c) cancelled.

Option (d), we can easily cancel it out. But I'm showing the work; a person delivers 20 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers, much faster than the person.

Hence option (a) is the answer.

Hope it helps :)

Answer:

The surface area of the figure is;

36·π cm²

Step-by-step explanation:

The parameters of the figure are;

The shape of the figure = A sphere

The radius of the sphere, r = 3 cm

The surface area of a sphere, A = 4·π·r²

Therefore, for the given sphere, we have;

The surface area of the sphere, A = 4 × π × (3 cm)² = 4 × π × 9 cm²

∴ The surface area of the figure (sphere), A = 36·π cm².

Answer: B is the correct answer

Step-by-step explanation:

If you do the math for each question to get a price a leaves you with 725 and b leaves you with 720 and c leaves you with 760 while d leaves you paying 800 so the lowest amount would be B.

Answer: B

Step-by-step explanation:

I'm pretty sure its B.

Since all 4 stores have a 5% sales tax already on them, we do:

800 x 5%

800 x 5/100

800 x 0.5 = 40

So now we go to all the stores and see which one is less than $40.

Answer A = 40 - 75 = -35 (Which is a price the store would have to pay but that's not a good option)

Answer B = 4

40 x 10%

40 x 10/100

40 x 0.10 = 4

Answer C = So if the store already pays sales tax which would be the 5% then our answer is $40

Answer D = This would just be $800 since the store says "no tax" and the store pays the 5%.

So, i'm pretty sure the answer is B instead of C. (i say this because a lot of people were saying it was C but C is completely wrong.)

sixteen because if u but a 1 under neath the 4 then cross up and multiply 4×4 is 16 then1×1 is 1 so ur answer would be 16

Answer: Erica has 2m-3 dollars

Step-by-step explanation:

Amount of dollars Yanyiah has = m dollars =$m

Erica has 2 times as many dollars as Yanyiah minus 3 dollars, can be expressed as =(2m-3)dollars,

We can therefore say Erica has 2m-3 dollars.

Answer:

2 and -2

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

Angle 1 is inside a triangle. Angles in a triangle add up to 180.

Angle 1 = 180 - 90 - 40 = 50.

Angle 2 is on a straight line (180 degrees), shared with angle 1. Therefore, angle 2 is 180 - Angle 1 = 130. Angle 3 and 4 can be calculated the same way Angle 2 was calculated (1=3, 2=4).

Angle 5 is 180 - 90 - Angle 3 which is 180-90-50 which is 40.

Angle 6 is 180 - Angle 5 = 180 - 40 = 140.

Angle 8 is the same as Angle 6

Finally, Angle 7 is 180-90 = 90.

She needs 3 3/4 cups more

Step-by-step explanation:

(I think you accidently put the 18 3/4 part twice) but anyways if you add 3/4 and 1/2 you get 1 and 1/4 that will be important later then you do 18 + 6 = 24 and then add your 1 and 1/4 to get a total of 25 1/4 then you just minus that from 29 and get 3 and 3/4

Answer:

188.24  (rounded)--- 188.2

Step-by-step explanation:

You want to first find the area of all the the different shapes you have...

you have 2 semicircles   A=  πr²/2    (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)

you have a rectangle A= b*h

you have a triangle A = b*h/2

Semicircles:  A= πr²   =     (3.14) 4²   =  (3.14*16)           =      50.24

rectangle:  A = b*h     =      12*8              =      96

Triangle:   A = b*h/2         =   12 * 7/2         =      84/2        =       42

then you add them up

50.24 + 96 + 42

= 188.24
