Answer:
Fine
Step-by-step explanation:
Answer:
±11.18
Step-by-step explanation:
the function is:
and to find the roots we need to find which values of 
makes the function result in zero:
solving for :
A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18
Answer:
A
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 100 = 256
a^2 = 156
a = 12.48
a = 12.5
Answer:
Step-by-step explanation:
Solve each inequality one at a time:
5x ≤ 21 + 2x and
3x ≤ 21 so
x ≤ 7
The other inequality is
3x + 3 ≥ 24 and
3x ≥ 21 so
x ≥ 7
If x is less than or equal to 7 AND greater than or equal to 7, then the solution is all real numbers.
Answer:
c. (5,-2), (3, 1), (4,2).
Step-by-step explanation:
The solutions are in the dark red area, with some on the continuous blue line but none on the red dotted line.
