What is an equation of the line that passes through the points (8,2) and (8,-4)

Answer:

B

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(3[tex]\sqrt{15}[/tex] ) + 2([tex]\sqrt{15}[/tex] ) ← distribute both parenthesis )

   = 6[tex]\sqrt{15}[/tex] + 2[tex]\sqrt{15}[/tex]

   = 8[tex]\sqrt{15}[/tex]

Answer:

, volume = [(3√3)/2]a2h cubic units

Step-by-step explanation:

The formula for the volume of a hexagonal prism is, volume = [(3√3)/2]a2h cubic units where a is the base length and h is the height of the prism.

Answer:

x=7 and y=4

Step-by-step explanation:

I will use the elimination method:

Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:

3x + y =25
+     +     +

2x - y = 10

Simplify:

5x=35

Divide both sides by 5:

5x÷5=35÷5

Simplify:

x=7

Substitute this into either equation 1 or 2 ( I chose 1):

3(7) + y = 25

21 + y = 25

Subtract 21 from both sides and simplify to get y:

21+y-21=25-21

y=4

Therefore x=7 and y=4

Answer:

568008

Step-by-step explanation:

i would do 100/6.9 to get 14.49

then i would multiply 14.49  by 39200 to get the "100%" of the copies.

Check the picture below.

so, the figure is really one big square, a 10x10, with four triangles in it, now, if we just get the area of the square, well 10x10 is just 100 in², and then get the areas of those three triangles, the yellow, purple and orange ones, and subtract their area from that of the larger square, what's leftover is the shaded triangle.  By subtracting the areas from the larger area, we're in essence making a big hole in the larger area, and what's leftover is what was never subtracted.

[tex]\stackrel{\textit{\Large Areas}}{\stackrel{square}{(10)(10)}~~ - ~~\stackrel{yellow~triangle}{\cfrac{1}{2}(10)(7)}~~ - ~~\stackrel{orange~triagle}{\cfrac{1}{2}(7)(10)}~~ - ~~\stackrel{purple~triangle}{\cfrac{1}{2}(3)(3)}} \\\\\\ 100~~ - ~~35~~ - ~~35~~ - ~~\cfrac{9}{2}\implies \cfrac{51}{2}\implies 25\frac{1}{2}[/tex]

Step-by-step explanation:

First what you want to do is add the -6s to 2s they have the same variables then add 4 to 10 which equals 14. I hope that helped! :)

Answer:

6x²+20y²+7xy

Step-by-step explanation:

Answer: s = -4

Step-by-step explanation:

s/4 + 15 = 14

We can subtract 15 from both sides:

s/4 = -1

We can multiply both sides by 4:

s = -4

Answer:

%17.70

Step-by-step explanation:

18% of $15 is $2.70

$15+$2.70=$17.70

Answer:

Tip: $2.70

Total: $17.70

Step-by-step explanation:

To find the tip amount, we have to find 18% of 15.

To find the total amount, we add the tip amount to the cost.

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches

Answer:

W=12 cm.

Step-by-step explanation:

If the total area is 180 sq. cm., and you multiply length times width to find area, this time it is inversed. So you do 180/15=12

Answer:

12 cm

Step-by-step explanation:

The area of a rectangle = length × width

We know that the length is 15 cm and the area is 180 cm² so we can substitute this into the equation:

180 cm² = 15 cm × width

Finally, we can divide both sides by 15 to find the width:

width = 180 ÷ 15

width = 12 cm

Answer:

19 + 2c

Step-by-step explanation:

19 is increasing two times Chau's height, (c), which gives you 19 plus twice c, (2c).

Answer:

C

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )

x = [tex]\sqrt{1120}[/tex] = [tex]\sqrt{16(70)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{70}[/tex] = 4[tex]\sqrt{70}[/tex]

Answer:

Yes, it is a function.

Step-by-step explanation:

We can see that using the vertical line test, none of the x points cross the line more than once, that means that it is a function, since it passes the vertical line test.
