Answer:

m = [tex]-\frac{1}{10}[/tex]

Step-by-step explanation:

To find the slope you use the equation y2-y1 / x2 - x1. For this problem, it would be 4 - - 5/ 4 - - 6. If we simplify this you will get 9/10. Therefore, The slope of the line will be 9/10.

Answer:

any real number

Step-by-step explanation:

your welcome

The correct answer is:

⇒ Any real number for x except 5, and any real number for y.

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.  This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.

Now, For given function is,

This means that 5 cannot be used for x in the other ordered pair.

Since there is no restriction on y in order to be a function, y can be any real number.

Thus, The correct answer is:

⇒ Any real number for x except 5, and any real number for y.

Answer:

The volume of the rectangular prism is 3/20 (or 0.15) mm³.

Step-by-step explanation:

The volume of the rectangular prism can be calculated as follows:

[tex] V = l*w*h [/tex]     (1)

Where:

l: is the length = 4/5 mm

w: is the width = 1/2 mm

h: is the height = 3/8 mm  

By entering the values of l, w, and h into equation (1) we can find the volume:

[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

if u add and if u subtract 4 from both sides u get 1x=19,divide frmo both sides and x=19

Answer:

x + 7 = 14  //  x - 5 = 2  //  x - 9 = -2  //  3x - 15 = 6 … (x = 7)

2x - 1 = 7  //  2x - 5 = 3 … (x = 4)

2x - 3 = 3  //  2x + 5 = 11  //  4x + 2 = 14  //  2x + 1 = 7 … (x = 3)

12x - 3 = 24  //  4x - 1 = 8 … (x = 9/4)

I hope I helped! I apologize if I made a mistake.

You can subtract 2y from both sides of the first equation and then plug that (x = 7 -2y) into the second one to get:

14 - 4y  + y = 5 -->

14 - 3y = 5 -->

-3y = -11 -->

y = 11/3 -->

x = 2/3
