A shelter has 5 dogs for every 4.cats. How many cats will the shelter have if they have 25 dogs?
olga_2 [115]

Answer:

20 cats

Divide both sides by 5 in order to get the variable by itself

100/5 = 20

x = 20

What is the equation of the line that passes through the point (-6,6) and has a slope of -5/3?
Harman [31]

Answer: The equation of the line that passes through the point (-6,6) and has a slope of -5/3 is y = -5/3x + -3.96.

Explanation:

y = 6, x = -6

By putting above values in equation (i)

6 = approximately -1.66 (-6) + b

6 = approximately 9.96 + b

approximately -3.96 = b

b = approximately -3.96

y = -5/3x + -3.96
