Juan solved the system of linear equations 8x-3y = -1 -5x +2y = 1 and a. First, he multiplied the equation 8x – 3y = -1 by 2 to get b. Next, he multiplied the equation -5x +2y = 1 by 3 to get c. Then he added the two resulting equations together to get d. Finally, he substituted the result into one of the original equations and solved for the variable to get e. Therefore, the solution to the system of linear equations written as an order pair is​

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

english, cause i can’t you

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

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
