Step-by-step explanation:
x-8= -3x²+4x-1
3x²+x-4x=-1+8
3x²-3x=7
3x²-3x-7=0
x²-x-3.5=0
Delta = -1²-(4)(1)(-3.5)
+1+14=15
x1=-1- sqrt(15) /2(1) =2.43
x2=-1+sqrt(15)/2(1) =-1.93
I don't think it is right but i tried my best
Work can be show by 2x3x90 that’s it
Y=x²-6x+14
y=(x²-2*3x +3²-3²)+14
y=(x²-2*3x+3²)+14-9
y=(x-3)²+5
a=1
p=3
q=5
a>0 ⇒ vertex is minimum
V(p,q) ⇒ V(3;5)
Regards M.Y.
10x +y = xy +26
There are thee (3) sets of numbers that satisfy this.
.. (x, y) = (3, 2) . . . . the number is 32
.. (x, y) = (5, 6) . . . . the number is 56
.. (x, y) = (9, 8) . . . . the number is 98
If you solve the equation for y, you get
.. y = 10 -16/(x -1)
so x-1 is a 1-digit factor of 16: 2, 4, 8. These give rise to the solutions above.
