medium box has best value
Answer:
Step-by-step explanation:
Distance = the square root of (x2-x1)2 + (y2-y1)2Added:Distance Formula: Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:square root of x2-x1 squared +y2-y1 squared
Answer:
Final factor is (x-9)(x+4)
Step-by-step explanation:
Given expression is 
.
Now we need to factor that expression
Find two numbers whose product is -36 and sum is -5.
Two such numbers oare -9 and +4. So we get:
Hence final factor is (x-9)(x+4)
Answer:
Step-by-step explanation:
-0.5
Step-by-step explanation:
If x is 1, plug it into the equation.
So, y=-3(1) + 2.5
-3(1) = -3
now add.
-3+2.5 = -0.5
so that should give you y = -0.5
Y = 3√(x-1).
Constraint: the radicand (x-1) ≥ 0 or x≥ 1
So the domain of this function is all Real for x ≥ 1
{x∈ R/x≥1}
