The incomplete, a quarter + a quarter = half
Answer:
To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.
Step-by-step explanation:
Start with
Add 2x to both sides:
Subtract 21 from both sides:
Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:
So, the answer is
Answer:
12 sqrt (10)
Step-by-step explanation:
S = (12 + 11 + 7) / 2 = 15
A = sqrt (s(s-a)(s-b)(s-c))
= sqrt (15(15-12)(15-11)(15-7))
= sqrt (15*3*4*8)
= sqrt (1440)
= 12 sqrt (10)
