Answer:
Angle BOC = 28; Angle AOB = 21
Step-by-step explanation:
Because angle AOC = AOB + BOC you can set the equation:
2x+10 + 4x-15 = 49
<solve for x>
6x - 5 = 49
6x = 54
x= 9
<plug in x for the angles>
BOC = 2(9) +10 = 28
AOB = 4(9) - 15 = 21
Answer:
(5, 4)
Step-by-step explanation:
The equation can be written in vertex form by adding and subtracting 25:
y = -(x^2 -10x +25) -21 +25
y = -(x -5)^2 +4
Then the vertex can be identified as (5, 4).
Answer:
See below
Step-by-step explanation:
a. here you are to multiply the two functions together:

b. here you are to subtract g from f:

c. here you are to compose g into f. In other words, pick up the whole g function and plug it into f wherever you see an x:

d. here you are compose f into g. In other words, pick up the whole f function and plug it into g wherever you see an x:

You now have to FOIL out the (3x-1) like so:
![2[(3x-1)(3x-1)]](https://tex.z-dn.net/?f=2%5B%283x-1%29%283x-1%29%5D)
which gives you

Distribute in the 2 and you'll end up with the answer:

Answer:
x can be cancelled
Step-by-step explanation:
we are given

Firstly, we will factor numerator and denominator
and then we can factor it


now, we can factor denominator


now, we can replace it

we can see that
both terms are having x common
so, x can be cancelled
So,
x can be cancelled
