Answer:
B
Step-by-step explanation:
Divide 168 by 2 to get 84, then divide 168 by 84 to get 2, now we can divide 231 by 84 to get our answer B.
First of all to make our equation simpler, we'll equal
to a variable like 'a'.
So,
Now let's plug
's value (a) into the equation.
Now we turned our equation into a quadratic equation.
(The variable 'a' will have a solution set of two solutions, but 'x' , which is the variable of our first equation will have a solution set of four solutions since it is a quartic equation (<span>fourth-degree <span>equation) )
Let's solve for a.
The formula used to solve quadratic equations ;
The formula is used in an equation formed like this :
</span></span>
In our equation,
t=16 , b=-41 and c=25
Let's plug the values in the formula to solve.
So the solution set :
We found a's value.
Remember,
So after we found a's solution set, that means.
and
We'll also solve this equations to find x's solution set :)
So the values x has are :
,
,
and
Solution set :
I hope this was clear enough. If not please ask :)
Answer:
1 3/4
Step-by-step explanation:
Frist he turned the proper fraction into an inproper which came to be 5/2. Then he subtracted 5/2 out of 3/4 Then after that you get 7/4 but then you make it a proper fraction you will get 1 3/4
Answer:
1. h(x) = 2ˣ-7 :
2ˣ - 7 = 131,065
2^x = 131,072
x = 17
2. k(x) = -(x/2) - 1 = 17
x/2 = -18
x = -36
3. g(x) = -(x-2)² = -36
x - 2 = 6
x = 8
4. f(x) = √x = 8
x = 64
h(k(g(f(64)))) = 131,065

Answer:
v = 18
Step-by-step explanation:
26 = 8 + v
v = 26 - 8
v = 18
