Answer:
1,075
Step-by-step explanation:
4,870-2575=2295
2295-1220=1075
Answer:
x= 5/2, x= -3
4x^2+2x-30=0; Factor that without the 0. Then you get 2 (2x-5) (x+3)=0.
2x-5=0 x= 5/2
x+3=0 x= -3
Hope this helps! :D
Answer:
(4, -3)
Step-by-step explanation:
The system of equations can be described a number of ways. One possible description is "a consistent pair of linear equations in two variables."
Perhaps you want to know the solution to this system of equations. I find it easiest to graph them. The attached graph shows the solution to be ...
(x, y) = (4, -3)
__
You can also use "elimination" to simplify the system to a single equation in a single variable. Adding 4 times the second equation to 3 times the first will do that.
3(5x +4y) +4(2x -3y) = 3(8) +4(17)
23x = 92 . . . . . simplify
x = 4 . . . . . . . . divide by 23
Substituting this value into the first equation, we have ...
5(4) +4y = 8
5 +y = 2 . . . . . . divide by 4
y = -3 . . . . . . . . subtract 5
The solution is (x, y) = (4, -3).

Step-by-step explanation:
t = .25u (given)
4 t = 4 (.25u) = u
then u = 50% of 2 u
Given:
The first four numbers in a pattern are 4, 2, 1, and 0.5.
To find:
The next three numbers in the pattern.
Solution:
We have a pattern,
4, 2, 1, 0.5
Clearly, it is a GP and the common ratio is
because each term is half of its preceding term.
Next term after 0.5 = ![0.5\times \dfrac{1}{2}=0.25](https://tex.z-dn.net/?f=0.5%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.25)
Next term after 0.25 = ![0.25\times \dfrac{1}{2}=0.125](https://tex.z-dn.net/?f=0.25%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.125)
Next term after 0.125 = ![0.125\times \dfrac{1}{2}=0.0625](https://tex.z-dn.net/?f=0.125%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.0625)
Therefore, the next three numbers in the pattern are 0.25, 0.125 and 0.0625 respectively.
