First, we have to make one of the x's have the same coefficient so they can cancel each other out (or eliminate)
3(x+y) = 3(2)
you're going to have to do it to both sides to keep it balanced
3x+3y=6
now line them up and add them
3x+3y= 6
+ (-3x+4y=15)
since the 3x and -3x add up to 0x and cancels each other, you're left with
7y = 21
divide both sides by 7
y=3
plug in the y into one of the original equations
x+y=2
x + 3 = 2
subtract 3 from both sides
x = -1
x = -1 , y = 3
Answer: Trinomial
Step-by-step explanation: The expression has 3 terms.
I think he is not correct because there is negative number so it can't be greater than one
To answer, we project the current balance to future worth.
FV = ($450) x (1 + 0.014)^5
FV = $482.40
Also, we convert the monthly amount to future worth by the equation,
FV = M x ((1 + r)^n - 1) / r)
Substituting,
FV = ($30) x (1 + 0.014)^5 - 1)/0.014)
FV = $152.3
Subtracting the calculated values,
Balance = $482.40 - $152.3
Balance = $328.14
The equation of a line in the slope intercept form is expressed as
y = mx + c
where
m represents slope
c represents y intercept
The given equation is
12x + 2y = 6
we would make this equation to look like the slope intercept equation.
12x + 2y = 6
If we subtract 12x from both sides of the equation, it becomes
12x - 12x + 2y = 6 - 12x
2y = 6 - 12x
2y = - 12x + 6
Dividing both sides of the equation by 2, it becomes
y = - 6x + 3
Thus, by comparing with the slope intercept equation,
slope = - 6
y intercept = 3
