15r + 8 = 11r - 20 solve for r and show your work in rows

r=-7

Step-by-step explanation:

r= -7

Step-by-step explanation:

15r+8=11r-20 (minus 11r from both sides)

4r+8=-20 (minus 8 from both sides)

4r = -28 (divide both sides by 4)

r= -7

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

$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
