Wu make and fill out the table using equation<br><br> Y = 4x - 2
Anvisha [2.4K]

Answer:

x =  \frac{1}{4} y +  \frac{1}{2}

Step-by-step explanation:

y =  4x - 2

first flip

4x - 2 = y

now add 2 to each side

4x + 2 = y + 2

now

4x = y + 2

divide by 4

4x \div 4 = 4 + 2 \div 4

so

x =  \frac{1}{4} y +  \frac{1}{2}

astra-53 [7]

Absolute value is simply the non-negative version of the number regardless of its symbol

So for the absolute value of 20? the answer is just 20.

For reference, the absolute value of -20 is also just 20.

Hope the explanation helps :)
