Answer:
(1, -8)
y= -8
x= 1
Step-by-step explanation:
7x-3y= 31
7x+y= -1
solve the equation
7x-3y=31
7x= -1-y
substitute the value of 7x into an equation
-1-y-3y=31
subtract -y to -3y
-1-4y=31
add both sides by 1
-4y=32
divide both sides by -4
y= -8
substitute the value of y into an equation
7x= -1-(-8)
distribute
7x=7
divide both sides by 7
x=1
(1, -8)
F(X) = 4x - 5
G(X) = 6x - 3
F(x) - G(x)
(4x - 5) - (6x - 3)
4x - 5 - 6x + 3
-2x - 2
-2(X + 1).
I believe this would be the simplified solution.
Answer:
B.35
Step-by-step explanation:
The sequence is
14, ,56,....
14 , x , 56
Think of it as 14 + d = x
x+ d = 56
d is the common difference
We now have 2 equations and 2 unknowns
Substitute the first equation in for x into the second equation
x+d =56
(14+d) +d = 56
Combine like terms
14 + 2d = 56
Subtract 14 from each side
14-14 + 2d = 56-14
2d = 42
Divide by 2
2d/2 =42/2
d = 21
The common difference is 21
Now we can find x
14 + d = x
14+ 21 = x
35 =x
The unknown term is 35
Answer:
1993
Step-by-step explanation:
Something is liquid if you can easily convert it into cash
So something like a car is not liquid (because it takes time to sell the car)
but something like a checking account is liquid (because it's easy to widthdraw your money)
so we have
1310+683= 1993
