Travis needs to mail 4 letters and 10 postcards. A letter needs a 37-cent stamp and a postcard needs a 25-cent stamp. How much m
kifflom [539]

Answer:

398-cent stamp for postage.

Step-by-step explanation:

For one letter, Travis needs                        37-cent stamp

For four letters, Travis needs                      37-cent stamp x 4 letters

                                                                   = 148-cent

Again,

For one postcard, he needs                        25-cent stamp

For ten postcards, he needs                       25-cent stamp x 10 postcards

                                                                   = 250-cent

Therefore, he will spend = (148-cent + 250-cent) = 398-cent stamp for postage.

Complete the equation of the line through (6,-6) and (8,8). Y =
Damm [24]

Answer:

7x-48

Step-by-step explanation:

we want our equation to look something like this

y=mx+b

let's start by solving for m (the slope) using the slope formula

\frac{y_2-y_1}{x_2-x_1}\\\\\frac{8-(-6)}{8-6}\\\\\frac{14}{2}=7

Which means, so far, our equation looks like this

y=7x+b

now we just need to solve for B

We can do this by plugging in a set of coordinates

-6=7*6+b

-6=42+b

-48=b

which means our equation is

7x-48
