Which systems have no solution? Select two answers. A. { 3 x − y = 6 − 6 x + 2 y = 12 B. { y = − 2 x + 10 y = 2 x − 2 C. { y = 3 x + 1 2 y = 6 x − 4 D. { y = 2 x + 10 y = 3 x − 2

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!

answer: b

step-by-step explanation:

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
