Write an equation in standard form of the line that passes through the given points:

Mathematics
1 answer:
Dafna1 [17]3 years ago
5 0

Step-by-step explanation:

The standard form for a line is Ax+By=C

First, we need to find the slope, or change in y over change in x. For the first one, this is

\frac{6-(-2)}{2-2}, which is impossible to find as we cannot divide by 0, meaning that this is constant horizontally -- in this case, x=2. Thus, we have 1*x+0*y=2.

For the second one, we can find the slope by getting

\frac{0-4}{3-(-3)} =\frac{-4}{6 }  = \frac{-2}{3}. We can then take the point (3,0) (it can be any point on the line) and get our equation to be y-0 = (-2/3) (x-3). Converting this to standard form, we can expand this to get

y= (-2/3)*x +2

(-2/3)*x+1*y = 2

Find the values of a , b and c in the equation below
stellarik [79]

Answer:

x^12 y^2 z^11

a= 12

b= 2

c= 11

Step-by-step explanation:

On the numerator you distribute the exponent 3 to the other exponents.

I think you multiply the 3 so you would get: x^15 y^3 z^12.

so it looks like x^15 y^3 z^12 / x^3yz

Then you subtract the top exponents from the bottom exponent because when you are dividing you subtract exponents. the exponent for y and z in the denominator is 1

and thats how i got x^12 y^2 and z^11. The exponents are a b and c

I hope that is right

Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 15 square meters. How many bags of topsoil does
____ [38]

Answer:

We need 4 topsoils

Step-by-step explanation:

I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.

My answer:

The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:

  • S = Height*the base length = 5 * 12 = 60 m^{2}  

So the bags of topsoil does Tom need to cover his flower bed is:

\frac{Area of the flower bed}{The area of the topsoil } = \frac{60}{15} = 4

We need 4 topsoils

To determine whether a cause-effect relationship exists between two variables, a researcher must use.
Thepotemich [5.8K]

To determine whether a cause-effect relationship exists between two variables, a researcher must use  an experimental approach.

<h3>What is cause-effect relationship?</h3>

A cause-and-effect relationship  is one which satisfies some conditions like:

  • two events occur at the same time and in the same place
  • one event immediately precedes the other

Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use  an experimental approach.
