Substitute y for -2 so <u>4x-3(-2)= 18</u>, which -3 * -2 is +6 so then it'd be <u>4x + 6 = 18</u>, then subtract 6 so <u>4x = 12</u>, then divide by 4 so <u>x = 3</u>. dont forget that in match the positive&negative signs count.
Make the denominator into 10x:
5x/10x +20/10x=x(x+4)/10x
5x+20=x(x+4)
5x+20=x²+4x
x²-x-20=0
(x-5)(x+4)=0
x=5 or -4
the third choice is correct.
Answer:
a = -2
h = -1
k = -6
Step-by-step explanation:
This is called the vertex form of a quadratic:
y = a(x – h)2 + k
To arrive at the answer, simply locate where each variable would be in place of the number.
