Answer:
Choice A
Step-by-step explanation:
A restriction of just a point is a hole, which means it is in the denominator
To determine this, we look at the denominators,
B and C do not have denominators,
Square roots cannot be negative, so they have larger restrictions
for D x+2 ≥0
x≥-2
Choice A is the only option that has a restriction that is a hole
x+2 ≠0
x≠-2
#3
1/6 (4) = 4/6 = 2/3
answer
2/3 acre in 1 hour
#4
3 x (4/3) = 4 ounces
answer
4 ounces per serving
x - c/2 = -3 c/2
Add c/2 to each side of the equation:
x = -2 c/2
Simplify the fraction on the right side:
<u>x = -c</u>
