$10(2x-1)-20x=(omitting\ the bracket)= 20x-10-20x=-10\\\
Result: -10$

Aliyah was counting her steps. It took her 1,317 steps to walk to the store, 561 steps to get to the park, and another 259 to ma

trapecia [35]

Answer:

Aliyah will take a total of 4274 steps.

Step-by-step explanation:

Given:

Number of steps from home to store = 1317 steps

Number of steps from store to park = 561 steps

Number of steps from park to friends house = 259 steps

So now we will find the Total number of steps from home to friends house.

Total number of steps from home to friends house can be calculated by adding Number of steps from home to store and Number of steps from store to park and Number of steps from park to friends house.

framing in equation form we get;

Total number of steps from home to friends house = $1317+561+259 = 2137\ steps$

Is same route is followed to home we can say that;

Total number of steps from friends house to home = 2137 steps.

So Total number of steps she will take next day will be equal to Total number of steps from home to friends house plus Total number of steps from friends house to home.

framing in equation form we get;

Total number of steps she will take next day = 2137 +2137 = 4274 steps

Hence Aliyah will take a total of 4274 steps.

Verify if f(x)= 5-3x/2 and g(x)= 5-2x/3 are inverses. Please show step by step.

mestny [16]

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.

<h3>Inverse of functions</h3>

In order to determine if the function f(x) and g(x) are inverses of each other, the composite function f(g(x)) = g(f(x))

Given the function

f(x)= 5-3x/2 and

g(x)= 5-2x/3

f(g(x)) = f(5-2x/3)

Substitute

f(g(x)) = 5-3(5-2x)/3)/2

f(g(x)) = (5-5+2x)/2

f(g(x)) = 2x/2

f(g(x)) = x

Similarly

g(f(x)) = 5-2(5-3x/2)/3

g(f(x)) = 5-5+3x/3

g(f(x)) = 3x/3

g(f(x)) =x

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.
