Obviously (hopefully) a square root function cannot be negative.
<span>Also, 4x-8 must be >= 0, otherwise the sqrt is undefined for the reals. </span>
<span>4x-8 >= 0 </span>
<span>4x >= 8 </span>
<span>x >= 2 </span>
<span>Then the range is [0, inf) </span>
<span>The domain is [2, inf)</span>
Answer:
no solution
Step-by-step explanation:
Any of the "-slope" or "slope-" formulas for a line cannot be used when the slope is undefined.
The equation of the desired line is x = -2. It cannot be put into the form y = ....
Answer:
(i)= 45 KPH, (ii) = 251 miles
Step-by-step explanation:
'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.
Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.
Answer:
3 tickets
Step-by-step explanation:
8x+3 = 9x
x = 3
6 - 3 = 3
5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2
answer is : 3 1/2 ( or 7/2)
