Paul [167]3 years ago
4 0

Answer:

Part 1) No solutions

Part 2)

part 3)

Step-by-step explanation:

Part 1) we have

-------> equation A

-------> equation B

Multiply the equation A by

-------->

Equation A and equation B represent parallel lines

therefore

Is a inconsistent system of equations

The system has no solution

Part 2) we have

-------> equation A

-------> equation B

Multiply equation A by

------>  ------> equation C

Multiply equation B by

------>  ------> equation D

Adds equation C and equation D

Part 3) we have

-------> inequality A

-------> inequality B

we know that

If a ordered pair lie in the solution set of the system of inequalities

then

the ordered pair must be satisfy the system of inequalities

case A)

substitute the value of x and the value of y in both inequalities

Verify inequality A

-------> is true

Verify inequality B

 ------> is not true

the point  is not a solution

case B)

substitute the value of x and the value of y in both inequalities

Verify inequality A

-------> is not true

the point  is not a solution

case C)

substitute the value of x and the value of y in both inequalities

Verify inequality A

-------> is true

Verify inequality B

 ------> is true

the point  is a solution

case D)

substitute the value of x and the value of y in both inequalities

Verify inequality A

-------> is not true

the point  is not a solution

1- no solution

2- 7

3-

R+b=7 <br> 3.75r+2.75b=22.25
stiv31 [10]

Answer:

Step-by-step explanation:

hello :

r+b=7... (*)

3.75r+2.75b=22.25.... (**)

use (*) :  r = 7 - b

put this value in (**) :

3.75(7 - b)+2.75b =  22.25

26.25 -375b +2.75b = 22.5

-375b +2.75b = 22.5 - 26.25

- b = -3.75

so : b  = 3.75

but : r = 7 - b

r = 7 - 3.75

r = 3.25

What is the common ratio of the geometric sequence below 625,125,25,5,1,...
shepuryov [24]

Answer: \frac{1}{5}

Step-by-step explanation:

In the geometric sequence we can see each time we are dividing by 5. That is the same as multiplying by \frac{1}{5} so that is the common ratio.

Solve for x please, explantion is not nesscary but it would help me
Ber [7]

Answer:

x = 100 degrees

Step-by-step explanation:

There are 360 degrees total in this figure. Since 160 is already shown, we can subtract it from 360 to solve for x. 360 - 160 = 200. So, 200 degrees is split among the remaining values, which are 2 x's. Since each x has the same value, we can divide 200 evenly among the two of them. 200/2 = 100. So, x = 100.

P.S.: Sorry if this is long-winded, I haven't taken geometry in a while. I hope I explained it well enough for you and other Brainly users.

A music website charges x dollars for individual songs and y dollars for an entire album. Person A pays $25.92 to download 6 ind
EleoNora [17]
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire song album = y dollars
Person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
Person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second we get
x = 0.99 dollars
Putting the value of x in the first equation we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
