Find the equation of the line perpendicular to y = 3x - 6 that runs through the point (-1, -3).

Answer:

Step-by-step explanation:

I'll get you the answer. You pick it from what you are given.

The slope of the perpendicular is m1 * m2 = - 1

m1 = 3

m2 = -1 / m1

m2 = -1 / 3

So far what you have is

y = (-1/3) x + b

Use the point go get b

x = -1

y = - 3

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

-3 = (-1/3)*-1 + b

-3 = 1/3 + b  

-3 - 1/3 = b

b = -3.33333  or

b = -3 1/3

b = -10/3              

So the answer is

y = (- 1/3) x - 10/3            or

y = (-1 / 3)x - 3.3333       or

y = (-1/3 )x  - (3 1/3)

Answer:

The correct option is B.

Step-by-step explanation:

The amount of money, in dollars, in a savings account after x years is given by  M(x) = 10000(1.03)^{x}

This above equation represents that $10000 becomes M(x) after x years at a rate of interest 3% compounded in each year.

Therefore, the value in the expression 1.03 represents that there is a 3 percent increase in the savings account each year.

So, the correct option is B. (Answer)

Worth 15 POINTS!<br><br> Create a story for the equation <br> y= -2x + 14
Ierofanga [76]

-2x+14 is the same as 14 - 2x

Let's say you started off with $14. If you want to buy a soda worth $2, then you have 14-2 = 12 dollars left. If you buy two sodas, then you spend 2*2 = 4 dollars with 14-4 = 10 dollars left.

In general, buying x sodas will cost you 2*x dollars and you have 14 - 2x dollars left over. The x is simply a placeholder for a whole number. For example, if x = 3, then...

14 - 2x = 14 - 2*3 = 14 - 6 = 8

meaning buying 3 sodas cost you $6 and you have $8 left over.

If y is the amount left over, then we can say y = 14 - 2x which is equivalent to y = -2x+14

note: graphing this equation will go through the two points (0,14) and (7,0) as shown in the image below. A graph is handy to help see various points on the line. Each point represents the amount of sodas you can buy (x) and the amount left over in your pocket (y). Keep in mind that neither x nor y can be negative, so it only makes sense to restrict the graph.

I need help on math.<br>h(x)=8x-10<br>h( )=62
andriy [413]

Simplifying

8x + -10 = 62


Reorder the terms:

-10 + 8x = 62


Solving

-10 + 8x = 62


Solving for variable 'x'.


Move all terms containing x to the left, all other terms to the right.


Add '10' to each side of the equation.

-10 + 10 + 8x = 62 + 10


Combine like terms: -10 + 10 = 0

0 + 8x = 62 + 10

8x = 62 + 10


Combine like terms: 62 + 10 = 72

8x = 72


Divide each side by '8'.

x = 9


Simplifying

x = 9
