When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.
Answer:
B. 58 feet to nearest foot.
Step-by-step explanation:
h = -16t^2 + 52t + 16
Convert to vertex form:-
= -16 [(t^2 - 3.25t) + 16
= -16 [ (t - 1.625)^2 - (1.625)^2 ] + 16
= -16 (t - 1.625)^2 + 42.25 + 16
= -16 (t - 1.625)^2 + 58.25.
The maximum height occurs when t = 1.625 seconds and its equal to 58 feet.
April would. She braids more, but at a slower pace. However, when they reach the 187 minute mark, April would have braided 77 times. Jeremy would have braided 68 times.
Answer:
p(x)=2x-40
Step-by-step explanation:
Substitute the variables
p(x)=10x-(8x+40)
p(x)= 10x-8x-40
p(x)=2x-40
Answer:
x=10
Step-by-step explanation:
x^2 + 24^2 = 26^2
x^2 + 576 = 676
x^2 = 100
√x^2 = √100
x=10
