Andreas93 [3]

Answer:

The answer to your question is below:

Step-by-step explanation:

A number is divisible by 9 if the sum of all the individual digits is evenly divisible by 9.

7,625 example 7 + 6 + 2 +5 = 20 it's not divisible by 9

4,932 4 + 9 + 3 + 2 = 19 it's not divisible by 9

9,180 18 it is divisible

2,969 26 it's not divisible by 9

9,180 18 it is divisible

4,932 18 it is divisible

2,969 26 it's not divisible by 9

Answer:

a) y = $\frac{7}{17}$

b) x = 4

Step-by-step explanation:

a) $\frac{3y+2}{5} =4y-1$

3y + 2 = 20y - 5

2 = 20y - 3y - 5

2 = 17y - 5

2 + 5 = 17y

7 = 17y

y = $\frac{7}{17}$

b) x² + 5 = 21

x² = 21 - 5

x² = 16

x = √16

x = 4

Determine whether the systems have one solution, no solution, or infinitely many solutions

Lerok [7]

Answer:

First system: no solution

Second system: one solution

Third system: one solution

Fourth system: infinite solutions

Fifth system: no solution

Step-by-step explanation:

First system: 3x-2y=3; 6x-4y=1

From the first equation: y = (3x - 3)/2

Using this value of y in the second equation:

6x - 6x + 6 = 1

6 = 1 -> System has no solution

Second system: 3x-5y=8; 5x-3y=2

From the first equation: x = (8 + 5y)/3

Using this value of x in the second equation:

5*(8 + 5y) - 9y = 6

40 + 25y - 9y = 6

16y = -34 -> y = -2.125

x = (8 - 5*2.125)/3 = -0.875

This system has one solution

Third system: 3x-2y=8; 4x-3y=1

From the first equation: x = (8 + 2y)/3

Using this value of x in the second equation:

4*(8 + 2y) - 9y = 3

32 + 8y - 9y = 6

y = 26

x = (8 + 2*26)/3 = 20

This system has one solution

Fourth system: 3x-6y=3; 2x-4y=2

From the first equation: x = 1 + 2y

Using this value of x in the second equation:

2*(1 + 2y) - 4y = 2

2 + 4y - 4y = 2

2 = 2

This system has infinite solutions

Fifth system: 3x-4y=2; 6x-8y=1

From the first equation: x = (2 + 4y)/3

Using this value of x in the second equation:

2*(2 + 4y) - 8y = 1

4 + 8y - 8y = 2

4 = 2

This system has no solution
