What is the slope of a line perpendicular to the line 6x-y=2?

Mathematics

DENIUS [597]3 years ago

Answer:

C) -1/6

Step-by-step explanation:

Slope of perpendicular line = -1/m

6x - y = 2

Slope - y-intercept form:

           -y = -6x + 2

Divide the equation by (-1)

    y = 6x - 2

m = 6

Slope of perpendicular line = -1/m = -1/6

Answer:

  (a)  (6, 2)

Step-by-step explanation:

The system of equations has one of them in y= form, so it lends itself to solution by substitution.

__

Using the equation for y to substitute into the first equation, we have ...

  2x -y = 10

  2x -(-1/2x +5) = 10 . . . . . substitute for y

  2x +1/2x -5 = 10 . . . . . eliminate parentheses

  5/2x = 15 . . . . . . . . . add 5, collect terms

  x = 6 . . . . . . . . . . . multiply by 2/5

Using the equation for y, we have ...

  y = -1/2(6) +5 = -3 +5

  y = 2

The solution is (x, y) = (6, 2).

Answer:

1.a=2

2.  C  x=2  and x=-3

Step-by-step explanation:

The standard form for the quadratic function is  

ax^2 +bx+c

so  we need to rewrite the function to be in this form

2x^2 -10 = 7x

Subtract 7x from each side

2x^2 -7x-10 = 7x-7x

2x^2 -7x-10 = 0

a =2, b= -7  c=-10


2.  The quadratic formula is

-b ± sqrt(b^2 -4ac)

----------------------------

2a


2x^2 + 2x=12

Lest get the equation in proper form

2x^2 + 2x-12 = 12-12

2x^2 +2x-12 =0

a=2  b=2 c=-12

Lets substitute what we know

-2 ± sqrt(2^2 -4(2)(-12))

----------------------------

2(2)

-2 ± sqrt(4+96)

----------------------------

2(2)

-2 ± sqrt(100)

----------------------------

4

-2 ± 10

----------------------------

4

-2 + 10               -2-10

-----------   and  --------------

4                             4

8/4   and -12/4

You operate the cash register at a retail store. A customer's total including tax, is $14.17, and you receive $20.00 as payment.
serious [3.7K]

Answer:

$ 20.00 - $14.17 = $5.83

Step-by-step explanation:

you have to take the amount of money given and subtract the total of the purchase , with the total including tax that makes it easier because you dont have to calculate it . so payment - total = change
