Help me pleaseeee :) for brainliest answer

Answer:

Dilation of 1/2 and then a reflection over y=2

Answer:

reflect GHI over x= -2, and dilatate G'H'I' by a scale factor of 2 from point G

Step-by-step explanation:

EFG is turned the other way, meaning that GHI was flipped. because EFG is bigger, and having a scale factor that's a whole number means it gets bigger, then this answer is correct because its both bigger and flipped in the picture.

Answer:

Positive correlation if right. Atleast consider brainlist:)

Step-by-step explanation:

Answer: Positive

Step-by-step explanation: It goes up over time instead of down, so it's positive.

Answer:

9 and 8

Step-by-step explanation:

It is 9 and 8 since 9^2 is 81 and 8^2 is 64 and they are the powers that 80 lies between.

Step-by-step explanation:

from,

An = 4n -13

A1 = 4 (1) - 13

> A1 = -9

A2 = 4(2) - 13

> A2 = -5

A3 = 4(3) - 13

> A3 = -1

A4 = 4(4) - 13

> A4 = 3

Answer:

2

Step-by-step explanation:

The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.

Answer:

Step-by-step explanation:

The ratio of the number of boys to the number of girls at your school is 5 to 8. Which statements are accurate according to this ratio?

The ratio of number of boys to girls is [tex]\frac{5}{8}[/tex]. That means:

[tex]\frac{boys}{girls} =\frac{5}{8}[/tex]

Let's look at the first choice.

a. If a class has 16 girls, it is reasonable to expect there are approximately 10 boys in the same class.

Make the amount as a fraction with boys over girls.

[tex]\frac{boys}{girls} =\frac{10}{16}[/tex]

10 and 16 can be simplified. The greatest common factor of 10 and 16 is 2, so divide by 2.

[tex]\frac{boys}{girls} =\frac{10 \div 2}{16 \div 2} =\frac{5}{8}[/tex]

Since the ratio is the same, choice a is correct.

Let's move onto the second choice.

b. In a group of 52 students, about 20 are boys.

If 20 students are boys, then the amount of girls is equal to 52 - 20, which is 32. Make the amount as a fraction with boys over girls.

[tex]\frac{boys}{girls} =\frac{20}{32}[/tex]

20 and 32 can be simplified. The greatest common factor of 10 and 16 is 4, so divide by 4.

[tex]\frac{boys}{girls} =\frac{20 \div 4}{32 \div 4}=\frac{5}{8}[/tex]

Since the ratio is the same, choice b is correct.

Let's go to the third choice.

c. The ratio of girls to total students is 8 to 13.

If the ratio of girls to total students is 13, that means there are 8 girls. The number of boys can be found by subtracting 8 from 13, which is 5. Make the amount as a fraction with boys over girls.

[tex]\frac{boys}{girls} =\frac{5}{8}[/tex]

Since the ratio is the same, choice c is correct.

Let's go to the fourth choice.

d. The Algebra class has 24 girls and 16 boys. This is the same ratio as girls to boys in the school.

Make the amount as a fraction with boys over girls.

[tex]\frac{boys}{girls} =\frac{16}{24}[/tex]

16 and 24 can be simplified. The greatest common factor of 16 and 24 is 8, so divide by 8.

[tex]\frac{boys}{girls} =\frac{16 \div 8}{24 \div 8} =\frac{2}{3}[/tex]

Since the ratio is not the same, choice d is not correct.

Lastly, the fifth choice.

e. If there are 208 students in the school, it is reasonable to expect there are 128 girls.

If there are 128 girls out of 208 students, the number of boys can be found by subtracting the number of girls from the amount of total students. 208 - 128 is 80, so there are 80 boys. Make the amount as a fraction with boys over girls.

[tex]\frac{boys}{girls} =\frac{80}{128}[/tex]

80 and 128 can be simplified. The greatest common factor of 80 and 128 is 16, so divide by 16.

[tex]\frac{boys}{girls} =\frac{80 \div 16}{128 \div 16}=\frac{5}{8}[/tex]

Since the ratio is the same, choice e is correct.

Answer:

6-11

Step-by-step explanation:

Answer: Check if numbers are prime. Composite numbers prime factorization (decomposing, breaking numbers down to prime factors). Inscribe them as a product of prime factors, in exponential notation.

Answer:

-1/3

Step-by-step explanation:

None of the answers are correct the slope is -1/3

The slope in a slope-intercept equation is always followed by x.

In the equation provided ( y=-1/3x+1/4) the number followed by x is -1/3 so the slope is -1/3.

If you are looking for the y=intercept it is 1/4, but the slope is -1/3.

Answer:

c

Answer:

y > 2x + 1

Step-by-step explanation:

1 is the y-intercept

The slope is 2/1 (aka 2)

Александр здравствуйте Я хочу предложить сотрудничество по сотрудничеству

Answer:

The answer is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]

Step-by-step explanation:

We need to factor [tex]3x^4y^3 - 48y^3[/tex]

Solution:

[tex]3x^4y^3- 48y^3= 3y^3(x^4 – 16)= 3y^3[(x^2)^2 - 4^2]= 3y^3(x^2 + 4)(x^2 - 4)= 3y^3(x^2 + 4)(x^2 - 2^2)= 3y^3(x^2 + 4)(x + 2)(x -2)[/tex]

So, the factorisation of [tex]3x^4y^3 - 48y^3[/tex] is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]

The answer is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]
