2. Complete the equivalent expression. -4(7 + 2x

which table represents vaiable solution for y=5x, where x is the number of tickets sold for the school play and y is the amount

MariettaO [177]

Answer:

The answer is the first table: (0, 0), (10, 50), (51, 255), (400, 2000)

Step-by-step explanation:

Let's check all of the tables:

Table 1:

x = 0, y = 0 ⇒ 0 = 5 · 0 ⇒ 0 = 0

x = 10, y = 50 ⇒ 50 = 5 · 10 ⇒ 50 = 50

x = 51, y = 255 ⇒ 255 = 5 · 51 ⇒ 255 = 255

x = 400, y = 2000 ⇒ 2000 = 5 · 400 ⇒ 2000 = 2000

50 pts. Solve this algebraic equation. -6x + 5 + 12x -6

TiliK225 [7]

−6x+5+12x−6 =−6x+5+12x+−6

=−6x+5+12x+−6 =(−6x+12x)+(5+−6)=6x+−1

6x−1 is your answer.

Identify the error or errors in this argument that supposedly shows that if ∃xp (x) ∧ ∃xq(x) is true then ∃x(p (x) ∧ q(x)) is tr

Ymorist [56]

The mistake lies in steps 3 and 5.

In fact, you know that there exists some element that satisfies p(x), and some element that satisfies q(x), but you can't assume that the same element satisfies p(x) and q(x) at the same time.

So, you are only allowed to say

p(c) existential instantiation from (2)

q(d) existential instantiation from (4)

and so you can't do the conjunction in step 6 anymore.

Here's an example: if you follow this logic, you would say something like:

"There exists a person who is born in Italy and there exists a person who is born in the USA. Therefore, there exists a person who is born in both Italy and the USA"

which is clearly false: altought there exists a person for each proposition, they are not the same person.

This is even easier if q is the negation of p:

"There exists a number greater than 10, and there exists a number lesser than 10. Therefore, there exists a number that is greater than and lesser than 10 at the same time"

which is clearly absurd

Evaluate each expression for g = -7 and h = 3 and match it to its value.

Arturiano [62]

Answer:

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Step-by-step explanation:

Given values of g and h are:

g = -7

h = 3

1. gh

The two numbers are being multiplied

Putting the values

$gh = (-7)(3) = -21$

2. g^2-h

Putting the values

$=(-7)^2-3\\=49-3\\=46$

3. g+h^2

Putting the values

$= -7 + (3)^2\\=-7+9\\=2$

4. g+h

Putting the values

$= -7+3\\=-4$

5. h-g

Putting the values

$= 3 - (-7)\\=3+7\\=10$

6. g-h

Putting values

$=-7-3\\=-10$

Hence,

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10
