Answer:
[0, +infinity).
Step-by-step explanation:
I believe you mean f(x) = |x|. This function, the "absolute value function," is v-shaped with vertex as (0,0), opening up. The domain is the set of all real numbers, and the range is [0, +infinity).
If this graph is translated 5 units to the left, the domain remains the same: all real numbers. Likewise, the range remains the same: [0, +infinity).
Answer:
Step-by-step explanation:
To answer this question, first we need to figure out how much of the board Rafi cut off.
To do this, we need to multiply the length of each piece by the number of pieces he cut off.
3 7/8 = 3.875
3.875 * 3 = 11.625
Now, because we knew Rafi cut off 11.625 feet off of the board, we just need to subtract this length from the length of the entire board to find the remaining length.
15 1/2 = 15.5
15.5 - 11.625 = 3.875
There is 3.875 feet or 3 7/8 of the board left.
Answer: (-0.385,0)(10.385,0)
Step-by-step explanation:
Subtract the 4 over so you have a full quadratic equation.
x^2-10x-4=0
Now plug a b and c in the quadratic formula

Hello from MrBillDoesMath!
Answer:
a) See Discussion below
b) Don't know what "m" refers to
Discussion:
Part a)
A triangle contains 180 degrees.
A + B + C = 180 (*)
where A is the angle inside the triangle.
From the diagram
B +C = 62 + 78 = 140
Substituting this in (*) gives
A + (140) = 180 => subtract 140 from both sides
A = 180 - 140 = 40
Now a line has 180 degrees so x + A = 180. But A = 40 (shown above) so x+ 40 = 180, or x = 140. That is, x = 140 - the sum of the measures of the two nonadjacent interior angles
Part b)
I can't answer this part is it is unclear what "m" refers to. Sorry.
Thank you,
MrB
