Answer:
4/5
Step-by-step explanation:
This linear function is represented by the model y = mx + b where y is the output value, x is the input value, b is the y-intercept and m is the slope. The coefficient of x is the slope when y has a coefficient of 1. In this equation, it's 4/5.

Which statement correctly describes the expression (-8)(-9)?
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?
a. If a class has 16 girls it is reasonable to expect there are approximately 10 boys in the same class.
b. In a group of 52 students about 20 are boys.
c. The ratio of girls to total students is 8 to 13.
d. The Algebra class has 24 girls and 16 boys. This is the same ratio as girls to boys in the school.
e. If there are 208 students in the school it is reasonable to expect there are 128 girls.
Please help!!
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.
choice a ✔
choice b ✔
choice c ✔
choice d x
choice e ✔
Your answer is choice a, b, c, and e.
The Daily Info charges a fee of plus per week to run an ad. The People's Paper charges per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper.
Complete question :
The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper
Answer:
650 + 80w < 145w
Step-by-step explanation:
Given that :
Number of weeks ad will run = w
Daily Info total cost :
650 + 80w
The People's Paper total cost:
145w
Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';
Daily Info total cost < people's choice
650 + 80w < 145w
650 < 145w - 80w
650 < 65w
650/65 < 65w / 65
10 < w
w > 10

What is the slope of the line?
1
1/2
-2
2
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.

Factor: 3x4y3 – 48y3.
Solution:
3x4y3– 48y3.
= 3y3(x4 – 16).
= 3y3[(x2)2 - 42].
= 3y3(x2 + 4)(x2 - 4).
= 3y3(x2 + 4)(x2 - 22).
= 3y3(x2 + 4)(x + 2)(x -2).
whats the answer?
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]

What is the slope of the line represented by the equation y=-1/3x+1/4?
-1/2
-1/4
1/4
1/2
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.

Which set of transformations would prove triangle GFE ~ triangle GHI?
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.
Give the first 4 terms of a sequence who has the explicit formula an = 4n – 13
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
