Answer:
Step-by-step explanation:
4y2 - 2x + 7 + 2y for x = 7 and y =2.
= 4(2)^2 -2(7) +7 + 2(2)
= 4(4) - 14 +7 + 4
= 16 - 14 + 7 + 4
= 13
Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4

is right 3 and up 4
P' ( x+3 , y+4)
P'(4+3 , -4+4)
p'(7,0)
