Answer:

-8

Step-by-step explanation:

In order to find the answer to this question you need to use the slope formula, substitute, subtract, and simplify if needed.

$(9,5),(4,1) = (x^1,y^1), (x^2,y^2)$

$m = \frac{y^2-y^1}{x^2-x^1} = \frac{9-1}{4-5}$

$9-1=8$

$4-5=-1$

$= -8$

Hope this helps.

Answer:

Step-by-step explanation:

Given that Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from

He got results as

France 1/3

Morocco 5/12

Spain 1/6

To find out what fraction of Amir's stamps are from France, Morocco, or Spain, we have to simply add the three as there is common element between any two pairs

Hence answer is

$\frac{1}{3} +\frac{5}{12} +\frac{1}{6}\\ =\frac{11}{12}$

Answer:

The volume of rectangular prism is $\frac{24}{105}$ inches³

Step-by-step explanation:

Given as :

The Length of rectangular prism = L = $\frac{2}{3}$ inches

The Breadth of rectangular prism = B = $\frac{3}{5}$ inches

The Height of rectangular prism = H = $\frac{4}{7}$ inches

Let The volume of rectangular prism = V inches³

A rectangular prism is a 3-D figure with 6 faces

Now, From formula of rectangular prism

Volume = Length × width × height

Or, V = L × B × H

Or, V = $\frac{2}{3}$ inches × $\frac{3}{5}$ inches × $\frac{4}{7}$ inches

or, V = $\frac{2\times 3\times 4}{3\times 5\times 7}$ inches³

or, V = $\frac{24}{105}$ inches³

So, The volume of rectangular prism = V = $\frac{24}{105}$ inches³

Hence The volume of rectangular prism is $\frac{24}{105}$ inches³ Answer

Expand & simplify 2 ( b + 4 ) + 5 ( b − 3 )

Usimov [2.4K]

Answer:

7b - 7

Step-by-step explanation:

You can use distributive property which is x (a + b) = x*a + x*b and x (a - b) = x*a - x*b. Therefore, the expression is 2*b + 2*4 + 5*b - 5*3 which is:

2b + 8 + 5b - 15, which is, if you combine like terms:

7b - 7
