Opposite sides and opposite angles of a parallelogram are equal and consecutive sides have sum 180

-y+8=127
-y=127-8
-y=119
y=-119

And

x+6=98
x=98-6
x=92

Answer: x = 92, y = -119

Step-by-step explanation:

Opposite sides of a parallelogram are equal.

x + 6 = 98

x = 92

127 = -y + 8

-y = 119

y = -119

This is a full assignment I’m struggling on if someone can answer them all and get most correct I will give you Brainliest for y

Effectus [21]

Answer:

Step-by-step explanation:

a) 1) Polynomial is closed under addition. In polynomial addition, only the coefficient change and variables and it powers does not change.

Example: Add 3x² - 2x + 7 and -2x² - 5x + 3

3x² - 2x + 7 - 2x² - 5x + 3 = 3x² -2x² - 2x - 5x + 7 + 3

= x² - 7x + 10

2)Polynomial is closed under addition. In polynomial subtraction, only the coefficient change and variables and it powers does not change.

Example: Subtract 3x - 2 from 4x + 2

4x + 2 - (3x - 2) = 4x + 2 - 3x + 2 = 7x + 4

3) Polynomial is closed under multiplication. In this, exponents of the variables are added according to the exponent rule. As the exponent of polynomials are whole numbers and whole numbers are closed under addition, the result will be a whole number.

-2x³ * 3x² = $-3*x^{3+2}=-3x^{5}$

4) Polynomial is not closed under multiplication. In division, we may get a negative exponent. So, it is not closed under division.

$\dfrac{x^{4}}{x^{9}}=x^{4-9}=x^{-5}\\\\x^{-5} \ is \ not \ a \ polynomial.$

What are m and b in the linear equation y=30x + 20

UkoKoshka [18]

Answer:

m = 30, b = 20

Step-by-step explanation:

1. The equation is written in slope-intercept form, so it follows the following equation: y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. As you can see, 30 is the value that took the place of m, and 20 is the value that took the place of b.

Therefore, m is 30 and b is 20.

What is the complement of 57?

umka21 [38]

Complements are numbers that add 90. Since one is 57, the other has to add to 57. So 33 would add with 57 to get 90.

In a group of 55 people, 3x+5 people like banana and x+5 people like apple. If all the people who like apple also like banana an

pishuonlain [190]

i. The number of people who like banana only is 20.

ii. The number of people who like none of the fruits is zero.

iii. The number of people who like at most one fruit is 30.

The question has to do with sets.

A set a collection of well ordered items

<h3>i. How to find how many people like banana only.</h3>

Since we have 55 people, 3x + 5 people like banana and x + 5 people like apple. If all the people who like apple also like banana and if 2x + 15 people like at least one of fruit then, we have that

3x + 5 + x + 5 + 2x + 15 = 55

3x + 2x + x + 5 + 5 + 15 = 55

6x + 30 = 55

6x = 55 - 25

6x = 30

x = 30/6

x = 5

Since the number of people who like banana only is 3x + 5.

So, number of people who like banana only is n = 3x + 5

= 3(5) + 5

= 15 + 5

= 20

So, the number of people who like banana only is 20.

<h3>ii. The number of people who none of the fruits.</h3>

Since from the question, a person likes at least one fruit, either banana, apple or both. No one likes none of the fruits.

So, the number of people who like none of the fruits is zero.

<h3>iii. The number of people who like at most one fruit?</h3>

To like at most one fruit, the person either likes apple or banana.

So, their sum is n = 3x + 5 + x + 5

= 4x + 10.

Since x = 5, we have n = 4x + 10.

= 4(5) + 10

= 20 + 10

= 30

So, the number of people who like at most one fruit is 30.
