B: -(x^2) reflects over the x-axis and +3 shifts it up by 3
X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
Answer:
i x = 0
ii x = 5,9
iii y = 12
iv y = 0
Step-by-step explanation:
0 = 12x²/(x - 5)(x - 9)
0 = 12x²
0 = x²
x = 0
ii vertical asymptotes at x = 5, 9
asymptotes occur as either term (x - 5)(x - 9) approaches zero
iii horizontal asymptote y = 12
function essentially becomes 12(∞²)/∞² = 12(1) as x goes to ±∞
iv y = 0 where x = 0
Answer:
Option D
Step-by-step explanation:
(10x + 13) + (12 + 9x) + ( 13x + 12) + 55 + 44 = 360
32x + 136 = 360
Subtract 136 from both sides;
32x = 224
Divide both sides by 32;
x = 7
Answer:
1st:Linear, 2nd:Non-Linear
Step-by-step explanation:
1st one is linear because you will add the same amount of money every day, so it's linear.But sometimes you will earn more or less in 2nd one, so that is non linear.
