Answer:

1. 14 cm

2. 20.4 cm

3. 24 - w

Step-by-step explanation:

Let's start with the last question, as it'll make answering the previous two a lot easier. In the 3rd question, we are asked to create a formula to find the length of a given rectangle, using its given perimeter of 48 centimeters and width of w centimeters.

Therefore, let the length of the rectangle be l, we can construct the following equation:

2l + 2w = 48\\\to2l = 48 - 2w\\\to l = \frac{48 - 2w}2\\\to l = 24 - w


Now we have a formula that defines our length, if given the width of the rectangle. The only thing from here on out is to substitute the given widths to the formula we just found.

1. w = 10 , therefore, l = 24 - 10 = 14.

2. w = 3.6 , therefore, l = 24 - 3.6 = 20.4.

On a coordinate plane, a line goes through (negative 4, 0) and (4, negative 4). A point is at (2, 3).
Valentin [98]

9514 1404 393

Answer:

  (b)  x +2y = 8

Step-by-step explanation:

The only offered line that includes the given point is ...

  x +2y = 8

__

We can check the other choices:

  x + 2y = 2 +2(3) = 2+6 = 8 . . . matches B (not A)

  2x +y = 2(2) +3 = 4+3 = 7 . . . . not a choice

_____

<em>Getting there from scratch</em>

The standard form equation for a line can be written from ...

  (y2 -y1)x -(x2 -x1)y = constant

  (-4 -0)x -(4 -(-4))y = constant . . . . using the given points (-4, 0) and (4, -4)

  -4x -8y = constant

For standard form, we need the leading coefficient to be positive, and we need common factors removed. We can get there by dividing by -4.

  x +2y = constant

The value of the constant will be whatever it takes for the given point to lie on the line. For (x, y) = (2, 3) to be a solution, we must have ...

 x +2y = (2) +2(3) = constant = 8

The desired line has the equation ...

  x +2y = 8

What is the 8th term of the geometric sequence 8,16,32
ratelena [41]

the 8th term of the geometric sequence 8, 16, 32 is 1024

<h2>Explanation</h2>

<u>we know that</u>

geometric sequence 8, 16, 32

<u>the </u><u>question</u><u> </u><u>is</u>

the 8th term

<u>the </u><u>answer </u><u>is</u>

first we have to find the ratio

\sf r=  \frac{ U_2}{U_1}  \\  \sf r=  \frac{ 16}{8} \\  \sf r = 2

than, we have to find the 8th term

\sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024}

If - 7 = 9 + x, then -3x + 5 = ?
Vikentia [17]

Answer:

53

Step-by-step explanation:

At first,

- 7 = 9 + x

By subtracting 9 from both sides, we get

-7-9=9+x-9

-16=x

Now,

By substituting the value of x in -3x + 5 , we get

-3x + 5

-3×(-16)+5

48+5
