Alexxx [7]2 years ago
4 0

Answer:

330=40x+50

Step-by-step explanation:

then you would -50 from both sides

280=40x

then you would divide both sides by 40 to isolate x

7=x

so that means it would take 7 weeks

Find the slope of the line through each pair (1,-19),(-2,-7)
expeople1 [14]

hello i see that no one has answered your question yet well im here to help:)

(1,-19),(-2,-7)

so here one way you can find the slope

i usually always use this to help me to keep it in order

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

(X1,Y1)(X2,Y2)

   X2-X1

   Y2-Y1

use this and your garanteed to get the right answer everytime

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

X = -2 – 1 = -3

Y = -7 – -19 = 12

once you do that you divide if possible

12/-3

which gives you -4

so your answer is -4

its really not hard you just got to get use to it

hope it help you:)

A kennel charge $25 per day to board dogs, where d represents the number of days. Upon arrival, each dog must have a one- time b
sergiy2304 [10]

Answer:

Option A. C(d)=25d+12

Step-by-step explanation:

Let

d -----> the number of days

C(d) -----> the total cost

we know that

The linear equation in slope intercept form is

y=mx+b

where

m is the rate or slope of the linear function

b is the y-coordinate of the y-intercept

In this problem we have that

C(d)=md+b

The slope of the linear equation is equal to the charge of $25 per day to board dogs

so

m=25\frac{\$}{day}

The y-intercept is the value of y when the value of x is equal to zero

In this problem the C-intercept is the total cost when the number of days (d) is equal to zero

The C-intercept is equal to the cost of the bath $12

so

b=\$12

substitute the values

C(d)=25d+12
