Ineed quick solve the system of equations using substitution. 3x + 2y = 7 y = –3x + 11 (6, –3) (5, –4) (6, –7)

The correct answer is (5, -4)

Step-by-step explanation:

To solve using substitution, we can take the second equation (y = -3x + 11) and use the value of y to replace y in the first equation. This will allow us to solve for x.

3x + 2y = 7

3x + 2(-3x + 11) = 7

3x - 6x + 22 = 7

-3x + 22 = 7

-3x = -15

x = 5

Now that we have that value, we can put it in for x in either equation and solve for y.

y = -3x + 11

y = -3(5) + 11

y = -15 + 11

y = -4

Therefore the correct answer is (5, -4)

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

i think its a.

hope this
