Explain and Show the equation of line perpendicular to y=-1x+2 going through the point (6, 3)

Mathematics

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

PLEASE HELP ME!! I can’t figure this out
DochEvi [55]
Hello!

The problem has asked that we write a point-slope equation of the line in the image above. Point-Slope Form uses the following formula:

y – y_{1} = m(x – x_{1})

In this case, M represents the slope while X_{1} and Y_{1} represent the corresponding X and Y values of any given point on the line.

We are given that the slope of the line is -\frac{5}{7}. We also know that any given point on a graph takes the form (x,y). Based on the single point provided in the image above, we can determine that X_{1} is equal to 6 and Y_{1} is equal to 2. Now insert all known values into the point-slope formula above:

y – 2 = -\frac{5}{7}(x – 6)

We have now successfully created an equation based on the information given in the problem above. Looking at the four possible options, we can now come to the conclusion that the answer is C.

I hope this helps!

Kryger [21]

Answer:

There are currently 50 states in the United States.

The number of states in 1795 in the United States = 15

Now, the fraction of the states that had become a part of the United States by 1795 is given below:

\frac{15}{50}=\frac{3}{10}

I need help on how to solve this equation C+(4-3c)-2=0 stp by step
Mumz [18]
Step 1-  Simplify brackets 
c + 4 - 3c -2 = 0
Step 2- Simplify c + 4 - 3c -2 to -2c + 4 - 2
-2c + 4 - 2 = 0
Step 3- Simplify -2c + 4 - 2 to 2c + 2
-2c + 2 = 0
Step 4- Subtract 2 from both sides 
-2c = -2
Step 5- Divide both sides by -2
Answer: c = 1

A box of national brand cornflakes is $2.09 for 12 ounces. A box of store label cornflakes is $3.09 for 20 ounces.
grin007 [14]

Answer:

A)

  • National brand cornflakes is 0.174 = .17/oz
  • Store label cornflakes is 0.514 = .15/oz

B) The larger box is cheaper per ounce.


C) 2.09 – .30 = 1.79 for 12 ounces. So than $1.79/12= .15/oz.

They  would both be the same so there would be no better deal.
