) Write matrix A, B) Write matrix B, C) Write the inverse of matrix A, D) Then solve each system of equations using matrices. Answers to each part should be written using integers or reduced fractions. 1) −3x + y = −28 3x − 5y = 20 2) −12x + 10y = 28 12x + 6y = 36 3) −3x + 8y = 11 x + 8y = 7

answer: 12

step-by-step explanation:

because yes

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

6 and 24

step-by-step explanation:

6 x 4 = 24
