Write a two-column proof to verify each conjecture: If -1/3n = 12, then n = -36. This is for geometry btw. Any help would be much appreciated, thanks.

Answer:

A: law

B:  The opposite of a number is its additive inverse. The sum of a number and its opposite is zero. (This is sometimes called the property of opposites ).

C: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

The mean difference in the game scores over the five games is = 5

The points achieved by the various team players =

To obtain the mean of the points achieved from the five

games the five scores are added together and divided by the number of games which is 5.

That is,

[tex] \frac{7 + 3 + 4 + 2 + 9}{5} [/tex]

[tex] \frac{25}{5} = 5[/tex]

Therefore the mean difference in game scores over the five games is = 5

Answer:

x=-1, y=-5

Step-by-step explanation:

y=3x-2 (1)

x-y=4 (2)

sub (1) into (2)

x-(3x-2)=4

x-3x+2=4

-2x=2

x=-1

sub x=-1 into (1)

y=3(-1)-2

 =-3-2

y = -5

Therefore: x=-1, y=-5 :))

Answer:

x = -1, y = -5

Step-by-step explanation:

y = 3x - 2

x - y = 4

x - y = 4

x - (3x - 2) = 4

x - 3x + 2 = 4

-2x + 2 = 4

-2x = 2

x = -1

x - y = 4

-1 - y = 4

-y = 5

y = -5

Check:

x - y = 4

-1 - (-5) = 4

-1 + 5 = 4

4 = 4

Answer:

$  263.42

Step-by-step explanation:

-275.78 + 539.20 = 263.42

The new balance in Mr. smith account will be $263.42.

We have Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account.

Assume that the new amount in his account will be [x]. Then -

[x] = 539.20 - 275.78

[x] = 263.42

Therefore, the new balance in Mr. smith account will be $263.42.

Answer:    30

Step-by-step explanation:

Formula to convert F to C:

(F -32) x 5/9

F = 63 + 10 = 73

73-32 = 41

41 x 5/9 = 22.77777

Rounded to the nearest degree = 23 C

Answer: 63 +10 =73 then you have to round it right

it would be 70 degrees Celsius

Step-by-step explanation:

it would be rounded to 70 because 73 cant be round to 80 the 3 is ot higher than 5

Answer:

-9 pounds / month

Step-by-step explanation:

A loss of 36 pounds is a negative number

-36

Divide by the number of months

-36 pounds / 4 months

-9 pounds / month

Divide total loss by number of months:

36 pounds / 4 months = 9 pounds per month.

Because it lost weight the integer would be negative 9 (-9)

Answer:

A. x ≥ -3 and x < 2, or -3 ≤ x < 2

Step-by-step explanation:

Remember solid dot means include, open dot means not include.

x ≥ -3: this means x is greater and equal (includes) -3.

x < 2: this means x is less than 2 and does not include it.

Answer:

A

Step-by-step explanation:

So on the number line you see a closed circle at -3 and an open circle at 2.

Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.

So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].

The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].

To combine it together, it would get [tex]-3 \geq x < 2[/tex].

Since option A is [tex]x \geq -3[/tex] and  [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

Answer:

(- [tex]\frac{15}{2}[/tex], 25 )

Step-by-step explanation:

Given the 2 equations

y = - 4x - 5 → (1)

y = - 2x + 10 → (2)

Substitute y = - 2x + 10 into (1)

- 2x + 10 = - 4x - 5 ( add 4x to both sides )

2x + 10 = - 5 ( subtract 10 from both sides )

2x = - 15 ( divide both sides by 2 )

x = - [tex]\frac{15}{2}[/tex]

Substitute this value into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25

Solution is ( - [tex]\frac{15}{2}[/tex], 25 )

Answer:

No.

Step-by-step explanation:

We will figure this out using subtraction.
