MrMuchimi

We want the ratio of calories of an orange to a cookie and are told that an orange has 35 calories and a cookie has 130 so:

O:C=35:130

The greatest common factor of 35 and 130 is the product of the shared primes of the numbers prime factorization.

35=5*7 and 130=2*5*13, so the GCF is just 5, so divide each term by 5

O:C=7:26

Write the equation of the line parallel to 3x-y=7 that passes through point (-5, -3)

IceJOKER [234]

<h2>Answer:</h2>

$\boxed{y=3x+12}$

<h2>Step-by-step explanation:</h2>

In this problem we know the equation of a line, which is:

$3x-y=7$

We also can write this equation as:

$y=3x-7$

This line has a slope $m=3$ which is also the slope of the line we are looking for because they're parallel. We also have a point $(-5,-3)$ . Therefore, we can write this equation as follows:
