4- (+) (-4) is similar to 4+4 by the rule of addition in integers that is if Negative + Negative then Add the number and put the sign of greater number.

<h3>What is integer?</h3>

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers. An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, and 3,043. 1.43, 1 3/4, 3.14, and other numbers that are not integers are some examples. Three categories of integers exist: Zero (0) (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers).

The rules of addition in integers says,

- + - = +

by this,

4-(-4)=8

by concept of addition,

4+4=8

What is the point-slope form of a line that has a slope of 3 and passes through point (1, 4)? y minus 4 = 3 (x minus 1) 1 minus

Tresset [83]

Answer:

y - 4 = 3(x - 1)

Step-by-step explanation:

It looks like you have slope 3 and a point (1, 4)

so it should be y - 4 = 3(x - 1)

which is your first choice: y minus 4 = 3 (x minus 1)

Answer:

9 t-shirts

Step-by-step explanation:

Well if she made a profit of $30 that would mean that you would subtract $84-$30 which would give you $54. Than you would divide 54/6 to find how much t-shirts she sold.

A horse corral is situated on a triangular plot of land. Two sides of the plot are 150 feet long and they meet at an angle of 55

Brrunno [24]

Answer : d. 438.5 ft

The diagram for the given statement is attached below.

Two sides AB and AC are equal so the angle B = angle C

WE know sum of three sides of a triangle = 180

angle A + angle B + angle C = 180

55 + B + C = 180

B + C = 180 -55 = 125

B and C are equal so we divide 125 by 2

angle B = 62.5 and angle C = 62.5

Now we apply sin law

$\frac{sin A}{a} = \frac{sin B}{b}$

$\frac{sin 55}{a} = \frac{sin 62.5}{150}$

150 * sin(55) = sin(62.5) * a

122.8728066 = sin(62.5) * a

a = $\frac{ 122.8728066}{sin(62.5)}$

a= 138.52 feet

To find perimeter we add all the sides

150 + 150 + 138.52 = 438.52 feet

Suppose that two players, R and C, write down letters of the alphabet. If both write vowels or both write consonants, then th

vladimir2022 [97]

Answer:

-0.075

Step-by-step explanation:

[Player R, Player C] cases & outcomes :-

(Vowel, Vowel) = (0,0)
(Consonant, Consonant) = (0,0)
(Vowel, Consonant) = (6,-6)
(Consonant, Vowel) = (-5,5)

Prob (R chooses consonant) = 75% = 0.75
Prob (R chooses vowel) = 1 - 0.75 = 0.25
Prob (C chooses vowel) = 30% = 0.30
Prob (C chooses consonant) = 1 - 0.30 = 0.70

Average Loss of R = Expected value of : he choses consonant & C choses vowel; he chooses vowel & C choses consonant

= (0.75)(0.30)(-5) + (0.25)(0.70)(6)

-1.125 + 1.05

= -0.075
