Solve the system of equations. y = -6x + 9 y = -3x + 3 a. ( 3, -2) c. ( 2, -3) b. ( -2, -3) d. No solution

pashok25 [27]

For this case we have the following system of equations:

$y = -6x + 9\\y = -3x + 3$

Equating the equations we have:

$-6x + 9 = -3x + 3$

Adding 3x to both sides of the equation:

$-6x + 3x + 9 = 3\\-3x + 9 = 3$

Subtracting 9 from both sides of the equation:

$-3x = 3-9\\-3x = -6$

Dividing between -3 on both sides of the equation:

$x = \frac {-6} {- 3}\\x = 2$

We look for the value of "and":

$y = -3 (2) +3\\y = -6 + 3\\y = -3$

Thus, the solution of the system is (2, -3)

Answer:

(2, -3)

What are the next three terms in the sequence 1, 7, 13, 19, ... ?

mote1985 [20]

Answer:

The next three terms in the sequence are: 25,31, 37

The required sequence is: 1, 7, 13, 19,25,31, 37

Step-by-step explanation:

We need to find the next three terms in the sequence 1, 7, 13, 19, ...

First we need to find the difference between the terms

If we observe:

First term ; 1

Second term is : 1+6 = 7

Third term is: 7+6 = 13

Fourth term is: 13+6 = 19

So adding 6 to previous term we can find the next term as observed by the pattern

Fifth term will be: 19+6 = 25

Sixth term will be: 25+6 = 31

Seventh term will be: 31+6 = 37

So, the next three terms in the sequence are: 25,31, 37

The required sequence is: 1, 7, 13, 19,25,31, 37

What is the slope of a line that is perpendicular to the line whose equation is 3x+2y=6 3 x + 2 y = 6 ?

Tanzania [10]

Answer:

The slope of the line perpendicular to the given line is 2/3

Step-by-step explanation:

step 1

Find the slope of the given line

we have

3x+2y=6

isolate the variable y

2y=-3x+6

y=-(3/2)x+3

The slope of the given line is m=-(3/2)

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, their slopes are opposite reciprocal of each other ( the product of their slopes is equal to -1)

m1*m2=-1

we have

m1=-3/2

m2=2/3

therefore

The slope of the line perpendicular to the given line is 2/3
