The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal

to each other

Step-by-step explanation:

Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means

7 + 7x = 7(x + 1/7)

7 + 7x = 7x + 7(1/7)

7 + 7x = 7x + 1

7x + 7 = 7x + 1

Now, subtracting 7x from both sides, we get:

7x - 7x + 7 = 7x - 7x + 1

(7 - 7)x + 7 = (7 - 7)x + 1

(0)x + 7 = (0)x + 1 thus their occurs a false statement:

7 = 1 ( we know, 7 >1)

Thus we can say that

7 + 7x is NOT equivalent to 7(x + 1/7)

Answer:

<h3> The second: f(-5) = 2</h3>

Step-by-step explanation:

x = -5

-5 < -4 and if x<-4 then f(x) = - 2x - 8

so:

f(-5) = - 2(-5) - 8 = 10 - 8 = 2

pi*0.9^2

pi*0.81
