Answer:

B ≥ 0.5 - A ≤ -2.5 = -3 is ( 0.5x ) - ( -2.5x) = -3x

Step-by-step explanation:

A and B = 2 skydiver's distance each from x = -2.5 and 0.5 inequality shows us when x = 0 then A ≤ -2.5 The second inequality shows us when x = 0 then B ≥ 0.5 here on number line we an keep closed circles and shaded lines in opposite direction each from 0 showing domain is x domain = -2.5 to 0 and x domain = 0 to 5 (using commas instead of to) The actual expression then goes B ≥ 0.5 - A ≤ -2.5 = -3 so we an just use ( 0.5x ) - ( -2.5x) = -3x

Dana can travel 9 miles in her rowboat in 6 hours against the current. With the current, it takes 4 hours to row the same distan

taurus [48]

Answer: The equations are

6x - 6y = 9

4x + 4y = 9

Step-by-step explanation:

Let x represent the speed of the row boat in still water.

Let y represent the speed of the current.

Dana can travel 9 miles in her rowboat in 6 hours against the current. This means that the total speed at which she travelled is

(x - y) miles per hour.

Distance = speed × time

Distance travelled against the current is expressed as

9 = 6(x - y)

6x - 6y = 9

With the current, it takes 4 hours to row the same distance. This means that the total speed at which she travelled is

(x + y) miles per hour.

Distance travelled with the current is expressed as

9 = 4(x + y)

4x + 4y = 9

What is the following product

dangina [55]

Option B is correct.

Step-by-step explanation:

We need to solve: $\sqrt[3]{x^2}\sqrt[4]{x^3}$

We know that: $\sqrt[n]{x}\sqrt[b]{x} =\sqrt[n*b]{x.x}= \sqrt[n*b]{x^2}$

Applying the above rule:

$\sqrt[3]{x^2}\sqrt[4]{x^3}\\=\sqrt[3*4]{x^2.x^3}\\=\sqrt[12]{x^5}$

So, Option B is correct.

How do i do this question? someone help

lesya [120]

There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60
