Answer:
y= -7 and x= -1
Step-by-step explanation:
To do this, line up the variables so it looks like this...
y-6x=-1
y-3x=-4
The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.
distribute negative to the bottom equation because the two equations have the same number variable which is y...
y-6x=-1
-y+3x=4
Y cancels out and it will be left with -3x = 3.
X = -1.... plug that in to any of the two equation and you get y = -7.
Hope I helped and have a nice day!!
Answer:
x=100
Step-by-step explanation:
the sum of all 3 angles in a triangle is always 180 so your problem is: 180 - 35 - 45
Let's take this step by step.
A car cost $43,900.
If it depreciates 48% in value in 3 years, we must find 48% of $43,900, and subtract that from its total value.
A 48% of $43,900 is:
$43,900 * 0.48 = $21,072
$43,900 - $21,072 = $22,828
The car is worth $22,828 in three years.
The y is 9:EXAMPLE took the test
