Answer:

Step-by-step explanation:

Coplanar points are the points on the same plane.

We see two planes, a vertical and a horizontal.

The points H, I and J are on the same vertical plane, so are coplanar.

Answer:

  83 m

Step-by-step explanation:

The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...

  8.26(10 m) = 82.6 m ≈ 83 m

_____

The distance formula will tell you the distances are ...

  AC = √(3² +1²) = √10

  BD = √(5² +1²) = √26

The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

Answer:

-9y^8

Step-by-step explanation:

-3y^4 * 3y^4

Multiply the coefficients

-3*3 = -9

Add the exponents since the base is the same

y^4 * y^4 = y^(4+4) = y^8

Put them back together

-9y^8

Answer:

Answer:

y = \frac{x}{36}y=

x

Step-by-step explanation:

Given

Length of string = x inches

Required

Determine the length in yards

Represent the equivalent length with y

Such that

y = x\ inchesy=x inches

Divide x by 36 to get equivalent in yards

y = \frac{1}{36} * xy=

36

1

∗x

y = \frac{x}{36}y=

Answer:

y=-6/7x-3

Step-by-step explanation:

On a graph, I plotted (7,-9) and the used the slope given but it was very off. On the slope -6/7x one of the plots is (7,-6). From the two lines, just go down 3 times and you would reach your plot again. What I mean is, do -6- 3=-9 so the answer is '- 6/7x-3. I used demos graphing calculator & calculator to make sure that my answer was 100% correct. You can use it too if you don't wan to use graph paper.

Hope this helps and comment or send a private message if you need help.

Answer:

[tex]2x + y = 5 \\ y = 5 - 2x[/tex]

[tex]2x - y + = 5 \\ - y = 5 - 2x[/tex]

[tex]x + 2y = 5 \\ 2y = 5 - x \\ 2y = 4 x [/tex]

Answer:

I assume you mean 16^(1/3) i.e. the cube root of 16

I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.

Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3

You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2

Hey there! Here's your answer:

No

Here's why:

PQRST is not a scale copy of ABCDE because the sides are not increased proportionally. A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape different sizes.

Proportional relationships are relationships that can be represented using a uniform or constant rate. The cost of food is not a proportional relationship because it does not use a uniform rate.

The missing table is as follows:

[tex]\begin{array}{cc}Bag&Cost\\0&0\\5&17.5&30&89\end{array}[/tex]

Let:

[tex]x \to[/tex] Bag

[tex]y \to[/tex] Cost

First, we calculate the slope (m) of the table using:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (5,17.5)[/tex]

The slope (m) is as follows:

[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m=\frac{17.5 - 0}{5-0}[/tex]

[tex]m=\frac{17.5}{5}[/tex]

[tex]m=3.5[/tex]

Also, calculate the slope (m) using the following points

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (30,89)[/tex]

The slope (m) is as follows:

[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{89 - 0}{30 - 0}[/tex]

[tex]m = \frac{89}{30}[/tex]

[tex]m = 2.97[/tex]

The calculated slopes are not the same. i.e.

[tex]3.5 \ne 2.97[/tex]

Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.

Answer:

  18 units

Step-by-step explanation:

The distance formula is used to find the distance between two points:

  d = √((x2 -x1)² +(y2 -y1)²)

For AB, the distance is ...

  d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5

The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.
