help i dont get it. please put answer with an explanation

Answer:

{x,y} = {1,1}

Step-by-step explanation:

[2]    6y = -14x + 20

 [2]    y = -7x/3 + 10/3

// Plug this in for variable  y  in equation [1]

  [1]    -10x - 6•(-7x/3+10/3) = -16

  [1]    4x = 4

// Solve equation [1] for the variable  x

  [1]    4x = 4

  [1]    x = 1

// By now we know this much :

   x = 1

   y = -7x/3+10/3

// Use the  x  value to solve for  y

   y = -(7/3)(1)+10/3 = 1

Solution :

{x,y} = {1,1}

Step-by-step explanation:

x=7

Answer:

The Answer Is 49.

Step-by-step explanation:

2x = 14. 2x  means 2 x ??? = 14. but you can find what "X" is you can find it out by divideing, 2 divided by 14 is 7 so X = 7. To find 6 - 7x you know that is means 6 - (7 x 7). 7 x 7 is 49, 6 - 49 is -42. You answer is -43 and X means 7.

Answer:

  6 feet

Step-by-step explanation:

The circumference is given by ...

  C = 2πr

Since we travel that distance in 3 seconds, our speed is ...

  2πr/3 = 12.56 . . . . . . feet per second

  6.28/3r = 12.56 . . . . using 3.14 for π

  r = 12.56(3/6.28) = 6

The radius of the merry-go-round is 6 feet.

Answer:

The dependent variable is distance, the equation is y = 33x, and the dragonfly will travel 792 miles

Step-by-step explanation:

ordered pairs:  (0, 0)  (2, 66)  (4, 132)  (6, 198)

slope of linear equation = change in y ÷ change in x

⇒ slope = (132 - 66) ÷ (4 - 2) = 33

Therefore, equation of the line: y = 33x

When x = 24, y = 33 × 24 = 792 miles

Distance is dependent on time, therefore distance is the dependent variable and time is the independent variable.

Answer:

44ft

Step-by-step explanation:

To find the answer, you need to first break down your shape. We can see that the 2 sides are identical so we can just multiply the area of on eof the sides by 2. The 2 sides equal 20 in all. Now lets look at the last section. To find an unknown side, we need to subract the 2 known sides. 8-5=3.   3x8=24

24+20=44

Hope this helps.

Answer:

Step-by-step explanation:

A1 = 2(5 x 2) = 20

A2 = 8 x 3 = 24

total = 20 + 24

      = 44 ft²

Answer:

Well you can’t really stack these percentages discounts.

Assuming it’s in the same order as the problem then

We can find the decimal equivalent by just dividing.

So think of it like this way.

Your getting 40 percent off, the original price.
The original price of course is a 100 percent since its the one and only price.

When your taking 0.4 percent off then its taking off 0.4 from the 1.00

So you have 0.6.

Your now paying 60 percent of the price.

Now the 30 percent.
Same thing except this times its 0.6.

Now 30 percent of 60 is 18 percent and then subtract that by 0.6 which is 0.42

Now for the final 15 percent
Same thing except this time its 0.15

15 percent of 0.42 is 6.3 percent, subtract that by 0.42 is 0.357

After the discounts were applied you’d only have to pay 0.357 or 35.7%

In order to find the total amount of discounts just subtract the amount we have to pay by the original which was 100 %. 100 - 35.7 = 64.3

Final net percentage is equivalent 64.3%

Answer:

[-8, infinity)

Step-by-step explanation:

Interval notation uses (, [, ], ) where the parentheses are exclusive and the brackets are inclusive. That means, we have:

The reason we don't use the square bracket for infinity is because you can never include infinity in your set

Answer: T

Step-by-step explanation:

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be $782.10

The volume of a cylinder is expressed as:
V = πr²h

h is the height = 40ft

r is the radius  = 1.5/2 = 0.75ft

Substitute:

V = π(0.75)²(40)
V = 3.14 * (0.75)²(40)

V = 70.65 cubic foot

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be 11.07 * 70.65 = $782.10
