Answer:

y+7 = -3 ( x-4)

Step-by-step explanation:

First find two points on the graph to find the slope

( 1,2) and ( 3,-4)

The slope is given by

m = ( y2-y1)/(x2-x1)

m = ( -4-2)/(3-1)

    = -6/2

    =-3

We can use the point slope form

y - y1 = m(x-x1)  where m is the slope and x1,y1 is a point on the line

We have two choices with a slope of -3

We can either use and x coordinate of -2 or 4

for  -2, the y coordinate is not shown

for 4 , the y coordinate is -7

Using ( 4, -7) and m = -3

y--7 = -3( x- 4)

y+7 = -3 ( x-4)

the vet charges $45 for an office visit and $10 for each vaccination your dog needs. write an eaquation
ser-zykov [4K]

Answer:

45+10x = y

Step-by-step explanation:

$45 -- stays the same no matter what so that's constant.

$10 -- this varies dependent on the number of vaccinations your dog needs, so you'd use a variable to represent the number of vaccinations (in this case I'm using variable "x").

So, for example if your dog needed 7 vaccinations, it would be: 45+10(7) = y -- answer being $115.

Write and solve equation.<br> What is 16% of 80?
PolarNik [594]
Question: What is 16% of 80?

You have to change the percentage to a decimal.

Remove the percentage sign and divide by 100 (% are based off 100)

16%⇒.16 

Now multiply .16 and 80

.16 * 80=12.8

Answer: 12.8

I need a Math EXPERT!!! Please help me in my math homework. WILL MARK AS BRAINLIST.
qwelly [4]

velocity is the slope (which can be calculated after finding the derivative)  →  given function f(x), velocity = f'(x).

acceleration is the slope of the velocity (which can be calculated after finding the derivative of the velocity)  →  given function f(x), acceleration is f''(x)

**************************************************************************************************

1a) A → B

f(x) = \frac{25}{3}x + 10

f'(x) = \frac{25}{3}

1b) B → C

f(x) = \frac{-15}{3}x + 50

f'(x) = \frac{-15}{3} = -5

1c) C → D

f(x) = 20

f'(x) = 0

Hope this helps!
