To do this problem you have to create two equations. one would be 18=4x+3y
an the other would be 9=2x+y. in this eqaution X is the number of DVDs and Y is the number of Video games. Then you solve for Y in the second equation and you get y=-2x+9. After that you then input this equation in for the other equation and you will have 18=4x+3(-2x+9). you solve for X in this problem and then you take the answer of x and put it in for x in the other equation.
so, 18=4x-6x+27
subtract 27 and add the 4x and -6x
-9=-2x
x=4.5
after this you put it in the other equation
9=-2(4.5)+y
multiply the -2 and 4.5
9=-9+y
add the 9
y=0
Answer:
-5
Step-by-step explanation:
add them together (-4)+(-1) make a t chart it'll help you out
Just type it into a calculator. (since there are three zeroes in 1000 just move the decimal point three times/spots to the left)
61.4/1000 = 0.0614
Answer:
Step-by-step explanation:
y - 2 = 3(x - 0)
y - 2 = 3x - 0
y = 3x + 2
