Answer:

y = -½x + 4

Step-by-step explanation:

1 = -½[6] + b

-3

4 = b

2y + x = 4 →2y = -x + 4 >> y = -½x + 2 [parallel to the above equation]

Parallel lines have SIMILAR <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>].

I am joyous to assist you anytime.

**I have a video that explains how to find the y-intercept, Perpendicular Equations, and Parallel Equations. I encourage you to watch the video to gain alot more knowledge from it, so you can better understand the concept. It is the second longest.

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best inte

stellarik [79]

Let

s--------> the length side of the cube

we know that

the volume of the cube is equal to

$V(s)= s^{3}$

if the length side s is equal to $2\ feet$

then

$s=2\ feet$

and the volume is equal to

$V(2)= 2^{3}$

$V(2)= 8\ feet^{3}$

therefore

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

D. A cube with side lengths of 2 feet has a volume of 8 cubic feet.

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth

bija089 [108]

Answer:

<h2>The answer is 13.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (10,-1) and B (-2,5)

The distance is

$|AB| = \sqrt{ ({10 + 2})^{2} + ({ - 1 - 5})^{2} } \\ = \sqrt{ {12}^{2} + ({ - 6})^{2} } \\ = \sqrt{144 + 36} \: \: \: \: \: \: \: \\ = \sqrt{180} \\ = 6 \sqrt{5} \: \: \\ =13.416407$

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>

Hope this helps you

If one would dissolve 60g of sugar in 300g of water, what would the concentration of sugar in this syrup be?

Pie

Density of water = 1000 kg/m^3
1 m^3 = 1000 litres

Therefore,
1000 kg/1000 l => 1 kg/l => 1000 g/l

Then, 300 g of water = 300/1000 l = 0.3 l

The concentration of the syrup = mass/amount of water = 60 g/0.3 l = 200 g/l
