Let's calculate the total cost per year:
6168 + 3280 + 2190 + 1200 = 12,838.
Four years will cost 12838 x 4 = 51,352
Your family will help you out with 17,600, so you will need to pay:
51352 - 17600 = 33,752
Answer: 3(x^2 + 4)/(x - 5)(x + 4)
Step-by-step explanation:
To simplify, begin with 3x^2 + 12 by dividing by 3 first: 3(x^2 + 4)
x^2 - x - 20 can be simplified into (x - 5) (x + 4). To find these terms, you have to figure out what two numbers multiply together to equal -20 but also add to -1.
Answer:
y=5
Step-by-step explanation:
The equation of a line can be written as y − y 0 = m ⋅ ( x − x 0 ) where ( x 0 , y 0 ) is any point that lies on the line. The gradient, m , of the line can be found using any two non-identical points that lie on the line. m = y 2 − y 1 x 2 − x 1 = 5 − 5 − 3 − 0 = 0 A gradient of zero indicates that the line is horizontal. The equation of the line can thus be simplified to y = y 0 In this case, both points have a y coordinate of 5. The equation of this line is therefore y = 5 .
