Answer:

-\frac{2}{3}

Step-by-step explanation:

-\frac{1}{9} + (-\frac{5}{9} )

Since you have two negative fractions you add them together and put a negative sign in front of the fraction.

1+5=6                                  so you have

-\frac{6}{9}                     Now you have to simplify 6 and 9 are both divisible by 3 so                             divide  both by 3 separately and then put it back in fraction form

-6÷3=-2

9÷3=3                    back in fraction form

-\frac{2}{3}                      You can't simplify any more so -\frac{2}{3} is your answer

An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of
Reika [66]

Answer:

98 cats and 19 dogs

Step-by-step explanation:

cat = c

dog = d

The animal shelter currently has a total of 117 animals

c + d = 117

c = 117 - d

the number of cats is 3 more than 5 times the number of dogs

c = 3 + 5d

subtitute c

117 - d = 3 + 5d

117 - 3 = 5d + d

114 = 6d

6d = 114

d = 114/6 = 19

so, the cat is 117-19 = 98

I need help with truth tables
Lerok [7]

The complete table of truth value for the composite proposition:

       p           q          ¬ q          p ∨ ¬ q            (p ∨ ¬ q) ⇒ q

       T           T             F              T                           T

       T           F             T              T                           F            

       F           T             F              T                           T

       F           F             T              T                           F                

<h3>How to fill a truth table with composite propositions</h3>

In mathematics, propositions are structures that contains a truth value. There are two truth values in classic logics: True, False. Composite propositions are the result combining simpler propositions and operators. There are the following logic operators and rules:

  1. Negation changes the truth value of the proposition into its opposite.
  2. Disjunction brings out "true" value when at least one of the two propositions is so.
  3. Conjunction brings out "true" value when the two propositions are so.
  4. Conditional form brings out "true" value when both propositions are true or only the consequent is true or both propositions are false.

Now we present the complete table of truth value for the composite proposition:

       p           q          ¬ q          p ∨ ¬ q            (p ∨ ¬ q) ⇒ q

       T           T             F              T                           T

       T           F             T              T                           F            

       F           T             F              T                           T

       F           F             T              T                           F

Explain why having three congruent angles in two triangles is not a good way to prove two
Marianna [84]

Draw an equilateral triangle with side lengths of 1. Each angle here is 60 degrees, which is true of any equilateral triangle.

Now draw another equilateral triangle that has side lengths of 2 units. Clearly this triangle is not the same size as the previous one, but the angles are all still 60 degrees.

We have an example in which there are 2 triangles with the same angles, but the triangles are not congruent. Therefore, having info about congruent angles only isn't sufficient to prove triangles to be congruent.

Find the slope, y-intercept, and x-intercept of the graph of 3x+7y=14 Show your work in detail.
Vika [28.1K]
3x + 7y = 14

Subtract 3x from both sides

7y = -3x + 14

Slope is equal to -3.
