Answer:

B) 3\sqrt{3}

Step-by-step explanation:

First simplify the radical on the right.

\sqrt{75} is equal to \sqrt{25} *\sqrt{3} , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.

Then we know \sqrt{25} is just equal to 25, which means the simplified version of \sqrt{75} is 5\sqrt{3}.

Then we can use this new representation to finish solving.

8\sqrt{3}-5\sqrt{3} =3\sqrt{3}, so the answer would be B

What is the equation of the line that is parallel to the line y = - 1/3x + 4 and passes through the point (6, 5)?
Lostsunrise [7]

Answer:

y=-\frac{1}{3}x+7

Step-by-step explanation:

we know that

If two lines are parallel then their slopes are equal

The equation of the given line is

y=-\frac{1}{3}x+4

the slope is m=-\frac{1}{3}

so

the slope of the parallel line to the given line is also m=-\frac{1}{3}

Find the equation of the line that is parallel to the given line and passes through the point (6, 5)

we have

m=-\frac{1}{3}

point\ (6,5)

The equation of the line in point slope form is

y-y1=m(x-x1)

substitute

y-5=-\frac{1}{3}(x-6)

Convert to slope intercept form

y=mx+b

isolate the variable y

y-5=-\frac{1}{3}x+2

y=-\frac{1}{3}x+2+5

y=-\frac{1}{3}x+7

Determine which system of equation has (-3,19) and (4,-23) as a solution?
grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

\frac{4--3}{-23-19} which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1

Who’s graph show a proportional relationship in which the value of y is one-half of the value of x
Sunny_sXe [5.5K]

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

That means it's the equation of a line passing through the origin.

case a) and case d) are discarded because the line does not pass through the origin

<u>case b) we have</u>

for x=2 y=4

y/x=k-------> 4/2=2------> k=2

y=2x-------> in this case the value of y is two times the value of x

<u>case c) we have</u>

for x=4 y=2

y/x=k-------> 2/4=1/2------> k=(1/2)

y=(1/2)x-------> in this case the value of y is one-half of the value of x

therefore

the solution is the case c) see the attached figure

Please Help Me!! Its for tomorrow and i rlly need help pls pls pls pls
DanielleElmas [232]

Answer:

perimeter = 6x + 15

Step-by-step explanation:

The perimeter of the triangle is the distance around the triangle.

We need to apply our ability to convert word problems in to mathematical expressions.

We were told that the bottom of the triangle is x units.

From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15

Four times the length of the bottom will be 4x .

12 more than 4 times the bottom will be 4x + 12.  

Hence another side of the triangle is 4x + 12.

Finally we were told that the last side is 3 more than the bottom, that will be      x + 3.
