How do I solve this ?

B, or in other words, the last solution is correct.

Step-by-step explanation:

Parallel lines haves the same slope, meaning that Street 2 will have the same slope as Street 1. Street one, according to the graph, has a slope of 1. Thus, Street 2 will have a slope of 1.

By this logic, we can get rid of A and C as choices, as they have a slope of -2 or 2. Now we have choices B and D left.

It can't be B, as the slope is -1, not 1.

Therefore, the answer is D.

they are simplified

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!
