Solve the following values for x and y 1) (8x + 7) 5y (7y - 34) (9x - 4)​

Solve The Following Values For X And Y 1) (8x + 7) 5y (7y - 34) (9x - 4)

Answers

Answer 1

9514 1404 393

Answer:

x = 11y = 17

Step-by-step explanation:

Vertical angles have the same measure, so we can equate expressions for each vertical angle pair:

top and bottom

  8x +7 = 9x -4

  11 = x . . . . . . . . . . add 4-8x to both sides

left and right

  7y -34 = 5y

  2y = 34 . . . . . . . . add 34-5y to both sides

  y = 17 . . . . . . . divide by 2

_____

Additional comment

As a check on the integrity of the problem, we can see if these angles form linear pairs.

  8x+7 = 8·11+7 = 95

  5y = 5·17 = 85

  95 +85 = 180 . . . . . . angle values have the expected relationship

Carter asks 40 of his friends what their favorite type of music is. He records the data in a circle graph to display the results. Carter compares the data for each person he interviewed. Which two types of music account for three-fifths of the people interviewed?


A) Alternative & Jazz
B) Rock & Hip Hop
C) Rock & Alternative
D) Rock & Jazz
E) Alternative & Hip Hop

(This is the hint my teacher gave me, but I still don't understand :/ "So you need to figure out what is three-fifths of 100. If you multiply both the numerator and denominator by 20 (because 20 x 5 = 100) you can find that percentage of people.
3 60
__ = ___
5 100
So which two types of music add to be 60% of the entire circle?")

Answers

Answer:

E) Alternative & Hip Hop

Step-by-step explanation:

A subgenre of hip hop music that encompasses a wide range of styles that are not typically identified as mainstream. AllMusic defines it as follows: "Alternative rap refers to hip hop groups that refuse to conform to any of the traditional stereotypes of rap, such as gangsta, bass, hardcore, pop, and party rap. Instead, they blur genres drawing equally from funk and pop/rock, as well as jazz, soul, reggae, and even folk."[2]

Quadrilateral A'B'C'D' Is the image of quadrilateral ABCD under a dilation.

What is the scale factor of the dilation?

Answers

Answer:

Scale factor = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Formula for the dilation to be used,

Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{A'B'}{AB}[/tex]

                    = [tex]\frac{1}{4}[/tex]

Therefore, scale factor by which quadrilateral ABCD has been dilated to form image quadrilateral A'B'C'D' is [tex]\frac{1}{4}[/tex].

What would be the Y-intercept in equation #1 of the following system? (Graphing)
x+y=7
6x-7y=18
(Worth 10 points)

Answers

I don't know what you mean by equation 1. I assume you mean x + y = 7 is equation 1.

If so, solve for y as step 1.

x + y = 7

y = - x + 7

The y-intercept is 7.

Your directions do not say to solve the system of equations.

If you need to solve by graphing, use DESMOS or your graphing calculator. The solution of the system of equations is the point on the graph where the two equations meet or touch each other.

Yes, because Han’s expression is 8(y-3) which is 8 x y which equals 8y and then 8 x -3 which equals -24. Priya’s is 2(4y-12). 2 x 4y = 8y and 2 x -12 = -24

Answers

Answer: -0.67, 0.22, -0.074

Step-by-step explanation:

This is a geometric sequence because it has a common ratio. The common ratio is divide by -3.

18 / -6 = -3

-6 / 2 = -3

Therefore, we'd continue that ratio.

2 / -3 = -0.67

-0.67 / -3 = 0.22

0.22 / -3 = -0.074

It may ask you to write that in fraction form^^

In that case, 2/-3, then 2/-3 / -3, etc etc. :)

Divide by -3
