Answer:
asymptotes: x= -4,-2 and no holes
Step-by-step explanation:
First we need to factor the denominator of the function
y = (x-1) / (x2 + 6x + 8)
x2 + 6x + 8 = 0
delta = b2 - 4ac = 36 - 32 = 4
x1 = (-6 + 2) / 2 = -2
x2 = (-6 - 2) / 2 = -4
So we have that x2 + 6x + 8 = (x+4)(x+2)
So our function is:
y = (x-1) / (x+4)(x+2)
As there is no common expressions in the numerator and denominator, there are no holes.
The asymptotes are when the denominator is zero, so:
(x+4)(x+2) = 0
x = -4 or x = -2
Answer:
the degree is 2
Step-by-step explanation:
because when you distribute x - 2 to x+3 = x^2 - x - 6. When you see an exponent in a trinomial that's the degree. If it's polynomial and has multiple exponents the degree is the highest number of the exponents.
Example:
2x^5 + x^3 - 4x + 1
The degree of this polynomial is 5 since it's the highest exponent number.
Question 2 is B because 55 in fraction is 55/100 simplified by 11/20
Answer:
x = 8.4
y = -2
Step-by-step explanation:
Step 1: Sub y=-2 into y=5x + 40
-2 = 5x + 40
Step 2: Solve for 'x'
-2 = 5x +40
-42 = 5x
x = 42/5
x = 8.4
Step 3: Solve for 'y'
y is given in the question, y=-2
Isn't it just 6.8? Pretty sure that is the answer
