Answer:

y-9 = -1/12(x-8)

Step-by-step explanation:

To write an equation of a line perpendicular to the graph of y = 12x-3 and passing through the point, we will follow the following steps.

The standard form of point-slope form of the equation of a line is  given as

y − y1 = m(x − x1),

m is the slope of the unknown line

(x1, y1) is a point on the line.

Step 1: We need to calculate the slope of the known line first,

Given y = 12x-3

from the equation, m = 12 on comparison.

Step 2: get the slope of the unknown line. since the line given is perpendicular to the line y = 12x - 3, the product of their slope will be -1 i.e Mm = -1

M = -1/m

M is the slope of the unknown line

M = -1/12

Step 3: We will substitute M = -1/12 and the point (8, 9) into the point-slope form of the equation of a line i.e y − y1 = M(x − x1),

M = -1/12, x1 = 8 and y1 = 9

y-9 = -1/12(x-8)

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that for the past 60 days, on 39 of those days she arrived at work before 8 AM while for the rest of those days she arrived after 8:30 AM, the probability that she will arrive at 8 AM on the next day she goes to work

Answer: 14 nickels and 18 quarters.

Step-by-step explanation:

Let x = Number of nickels , y = Number of quarters

As per given , we have

x+ y= 32            (i)

0.05x+0.25y= 5.20              (ii)

Multiply (ii) by 4 , we get

0.2x+y = 20.8          (iii)

Subtract (iii) from (i) , we get

0.8x = 11.2

[tex]\Rightarrow\ x=\dfrac{11.2}{0.8}\\\\\Rightarrow\ x = 14[/tex]

Put value of x in (i) , we get

y =32-14 = 18

Hence, we have 14 nickels and 18 quarters.

-8-6=4x-3x

-14=x

Answer:

x = -14

Step-by-step explanation:

3(x - 2) = 4x + 8

~Distribute left side

3x - 6 = 4x + 8

~Add 6 to both sides

3x = 4x + 14

~Subtract 4x to both sides

-x = 14

~Divide -1 to both sides

x = -14

Answer:

x² + y² is equal to = (4 / 81)(845m² + 78m + 18)

Step-by-step explanation:

We first need to get the values of x and y, which can be done using a system of equations, substituting one of the two functions into the other:

Given:

y = 2x + 2

3x + 3y = 26m

Then:

3x + 3(2x + 2) = 26m

3x + 6x + 6 = 26m

9x + 6 = 26m

9x = 26m - 6

x = (26m - 6) / 9

Now we can solve for y:

y = 2x + 2

y = 2(26m - 6) / 9 + 2

y = 2(26m - 6) / 9 + 18 / 9

y = (52m - 12 + 18) / 9

y = (52m + 6) / 9

Now we can sum up their squares:

x² + y²

= ((26m - 6) / 9)² + ((52m + 6) / 9)²

= (676m² - 312m + 36) / 81 + (2704m² + 624m + 36) / 81

= (3380m² + 312m + 72) / 81

= (4 / 81)(845m² + 78m + 18)
