Who knows proportional relationships? and how to solve these both

Mathematics

ExtremeBDS [4]3 years ago

"Porportional Relationships" means that the rate in which it increases is the same.

For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).

Now, look at the first one.

From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

NOT PROPORTIONAL

Look at the second one.

From y to x, y being 12, x being 10, you divided 1.2

Now, look at the next one. 30/25 = 1.2

Finally, the last one. 48/40 = 1.2

Because all of them are 1.2, the answer is proportional

PROPORTIONAL

The table below shows some inputs and outputs of the invertible function f etc ​
Snowcat [4.5K]

Answer:

(a)\ f^{-1}(-15) = -6

(b)\ f^{-1}(4) + f(9)=0

Step-by-step explanation:

Given

The attached table

(a)\ f^{-1}(-15)

This represents an inverse function.

So, we look into x row for its value.

i.e.

f^{-1}(-15) = -6

(b)\ f^{-1}(4) + f(9)

Just like (a)

f^{-1}(4) = -11 ---- by looking into the x rows

f(9) = 11

So:

f^{-1}(4) + f(9)=-11 + 11

f^{-1}(4) + f(9)=0

Cual es el resultado de 10x + 8 = 2 - 2x
castortr0y [4]

Answer:

x=-1/2

Step-by-step explanation:

Move -2x to the other side by adding 2x on both sides:

12x+8=2

Move 8 to the other side by subtracting  8 on both sides:

12x=-6

Divide by 12 on both sides:

x=-1/2

Hope this helps!
