Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 12 + c ⇒ c = 5 - 12 = - 7

y = 3x - 7 ← equation of line

.At a certain animal shelter, the ratio of puppies to adult dogs is 7 to 4. This week there are a total of55 dogs in the shelter
Advocard [28]

Answer:

There are 35 adult dogs and 20 puppies

<em></em>

Step-by-step explanation:

<em>Represent the puppies with P and the Adult dogs with A</em>

Given

A : P = 7 : 4

Dogs = 55

Required

Determine A and P

First, we need to sum the ratios;

Total = A + P

Total = 7 + 4

Total = 11

Adult Dogs is then calculated as follows;

A = \frac{A\ Ratio}{Total} * Dogs

A = \frac{7}{11} * 55

A = \frac{385}{11}

A = 35

Puppies is calculated by subtracting the number of adult dogs from the total

P = Dogs - Adult\ Dogs

P = 55 - 35

P = 20

<em>Hence;</em>

<em>There are 35 adult dogs and 20 puppies</em>
