Answer:
a) 2x - 3y + 8
Step-by-step explanation:
Problem: 2x + y - 4y + 8
Solve: y - 4y
Put it back into the expression: 2x - 3y + 8
To transform the diameter to the radius you will divide the diameter by 2
Put 3 divided by 16 into your calculator
X^2=16
x= 4 OR x=-4
The picture attached below is your answer because it’s between 4 and -4.
4/10= 0.4
So if 0.4x10=4, That means that 4. Is 4/10 of 10.
