2x + 4y = 60 x + 4y = 36 a. x = 11, y = -8 b. x = 2, y = 16 c. x = -8, y = 11 d. x = 8, y = 7

C.  x=-8, y= 11

Step-by-step explanation:

-2x+4y= 60

-2 (-8) + 4 (11)= 60

16+44= 60

60= 60

x+4y= 36

-8 + 4(11)= 36

-8 + 44= 36

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
