What is the solution of this linear system? 3x + 5y = -1 2x − 5y = 16 a. (-3, 2) b. (-3, -2) c. (3, -2) d. (2, -3)

3(3)+5(-2)=-1

9-10=-1

2(3)-5(-2)=16

6+10+16

C. (3,-2)

eve and marks ratios are equivalent

step-by-step explanation:

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!
