Simplify the numerical expression
2-(5.6-4^2)+7=

19.4

Step-by-step explanation:

2-(5.6-4^2)+7

PEMDAS

Parentheses first

(5.6-4^2)

Exponents

5.6 -16

Then subtract

-10.4

Replace the parentheses with -10.4

2-(-10.4)+7

Now add and subtract from left to right

2+10.4+7

19.4

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

its the fourth option
