Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
Step-by-step explanation:
All you have to do is
5-2(the number written on the x)
For example, the first given is - 1
5 - 2(-1)
The answer is 7
Answer:
H.C.F. is 48
Step-by-step explanation:
I hope this will help u
<span>it is an implicit function, (for high school students)
1) d(4x2+y2)/dx=d(48+2xy)/dx, after the differentiation, we obtain
8x + 2y .dy/dx = 2y + 2x .dy/dx
</span>8x - 2y = 2x .dy/dx - 2y .dy/dx, 4x - y = (x .- y ).dy/dx, and then
dy/dx = y-4x / y - x
2) when x cordinate is 2
we have 4(2^2) + y^2 = 48 + 2 . 2 y, and the y^2 - 4y - 32=0, after solving the quadratic equation we find y = - 8, or y = 4, this the positive y coordinate, the answer is y = 4
3) Let be P (xp, yp) the point, since P is the point at which the line tangent to the curve at P is horizontal, so we can write 4xp2+yp2=48+2xpyp, but xp=2, we have yp^2 - 4yp - 32=0, so P(2, 4)
