I can help you with one and 2 1hd 2 is 2d9
Answer:
Step-by-step explanation:
hello :
y=x²-10x+16 in the form y=(x-h)²+k
y= x²-2(5)(x)+16
y = x²-2(5)(x)+5²-9
y= (x-5)²-9 when h=5 and k = -9
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
CE (CE + CD) = BE(BE + AB)
(x+4) [1+(x+4)] = (x+1)[11+(x+1)]
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
4x = 8
x = 2
answer
x = 2
Line r is parallel because they don’t intersect
