Answer:
Domain:
[-5,-2) U (-2,3.5) U (3.5,5]
Range:
[-3 0) U (0,5]
It is not a function because x = 1 has two different outputs (3 & 5)
2 + 2 equals to 4
You can do it on the calculator too.
Answer:7/8 of an inch
Step-by-step explanation: 1 and 1/4 inch is 5/4 inches, which can be converted into 10/8
10/8-3/8=7/8
Answer:
a = 
b= 4
Step-by-step explanation:
It's a 30-60-90 triangle based on the given picture. A right triangle too
Use sine, cosine, and tangent to solve for the side.
To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.
OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and
for long leg
So either way, b = 4
To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.
OR you can use the same rule, 30-60-90 triangle to save time
a will end up = 
Answer:
Step-by-step explanation:
this is the same equation, the system has infinitely many solutions
