Hey there!
If we use pemdas:
P - Parentheses
E - Exponents
M - Multiplicatiom
D - Division
A - Addition
S - Subtractiom
We know we have to evaluate the exponent first. Two to the rid power is equal to 8. Therefore, we have:
2 - 4/2 + 8
Next, we do the division. -4/2 = -2, so we have:
2-2 + 8 = 0 + 8 = 8
Hope this helps!
Since the denominator cannot be zero, you can set 4z+1=0 to find the excluded values.
4z+1=0
4z=-1
z=-1/4
And thus, z cannot equal -1/4
Answer:
1
Step-by-step explanation:
3/2 = 2/2 * 1/2
2/2 = 1
So 3/2 = 1
Answer:
-2. Not really sure on this one because there is only one equation, so I think it is impossible.
Step-by-step explanation:
x=4-y
x+y-6
4-6=-2
