Starting at the origin, go five spaces up and three spaces to the left. Which point is plotted using these directions?
pentagon [3]

Answer:

(-3,5)

Step-by-step explanation:

If you start at the origin (0), going up 5 spaces will leave you at 5 for your y plot. Then, 3 spaces <em>left</em> leaves you at -3 for your x. However, when writing down plots, you write x before y. So, you are left with (-3,5) as your coordinate plot for the final answer.

The ratio to cats at an animal shelter 3:1. if there are 56 dogs and cats in all, how many more dogs than cats are there??
Black_prince [1.1K]

Answer:

There are 28 more dogs than cats at the animal shelter.

Step-by-step explanation:

If the ratio of dogs to cats at an animal shelter is 3:1, that means there are 3 dogs for every 1 cat.

The way I think about it is I try multiplying every number by 3 and 1, kind of like process of elimination.

After using every number from 1-13, I finally got to 14. Now, 3 x 14 = 42 and 1 x 14 = 14. Add 42 + 14 and you will get 56.

So there are 42 dogs and 14 cats at the animal shelter.

However, it is asking for how many more dogs than cats there are, so you have to subtract 42 - 14 and the answer is 28 more dogs than cats.

Determine if the statement below is always true, sometimes true, or never true. When x is a
andrew11 [14]

Answer:

Sometimes

Step-by-step explanation:

When x is a nonzero integer, then x can be

  • negative;
  • positive.

If x is negative, then -3x is positive (multiplying negative number by -3 you get positive number).

If x is positive, then -3x is negative (multiplying positive number by -3 you get negative number).

So, the statement "When x is a nonzero integer, the quantity -3x will be negative" is sometimes true.

Find the slope of the line between the coordinates (-6,-13) and (3,-1)
Finger [1]

To find the slope of this line, we must use the equation:


slope=\frac{x_{2}-x_{1}}{y_{2}-y_{1}}


Where (x_{1}, y_{1}) and (x_{2}, y_{2}) can be assigned to either point.


Let's use (-6, -13) as the point "1" and (3, -1) as the point "2":


slope=\frac{3-(-6)}{-1-(-13)}


slope=\frac{9}{12} =\frac{3}{4}


So now we know that the slope between these two points is \frac{3}{4}.
