Answer:
y = (75x + 500)
Step-by-step explanation:
To find the linear model,
Let y = monthly balance of the savings
x = months of the savings
With savings account with $500 which is fixed
deposits = $75
Then the model is
y = (75x + 500)
You first have to set up the two equations. Y is equal to the total number of gallons in a tank and x is equal to the number of hours the tanks are filling.
Since the two equations both equal y I can make them equal each other. I then solved for x as you see and got -4.
Once I found my x value I now needed to find my y. You only needed to chose one equation to solve for y, so I decided to do the first one. I plugged in -4 where my x value currently was and solved for y. I got 2.
If you have any questions please comment!! Hope this helps!!
Answer:
Well do you know the butterfly method
you multiply 2 by x+1 and 4 by x + 2
Step-by-step explanation:
2(x+1) + 4(x+2) = 3(x-3) -2(x - 1)
2x + 2 + 4x + 8 = 3x - 9 - 2x + 2
2x + 4x +8 = 3x - 2x -9 +2
6x + 8 = x -7
6x - x = -7 -8
5x = -15
x = -15/5
x = -3
Answer:
8
Step-by-step explanation:
Let the width of the rectangle be x. Then the length would be x+2
Area=(length)*(width)
48=x(x+2), => x=6. Width is 6 and length is 8
