Answer:
x= -6 twice
Step-by-step explanation:
x^2-3x-10/x^2+12x+36
By using undefined fraction we only take the denominator and equate it to 0
x^2+12x+36=0
x^2+6x+6x+36=0
(x^2+6x)+(6x+36)=0
x(x+6)+6(x+6)=0
(x+6)(x+6)=0
x+6=0 or x+6=0
x= -6 or x= -6
therefore x= -6 twice
Answer:
B
Step-by-step explanation:
To put an equation in point slope form, use the equation y-y1=m(x-x2)
If the equation is y-(-4)=2(x-(1))
Then the x value must be 1 and the y value must be -4. The answer is (1,-4)

Before sales tax he would have to pay $40 * (1 - 0.25) + $100 * (1 - 0.35) = $30 + $65 = $95.
With a 6% sales tax he'd have to pay 1.06 * $95 = $100.70.
i hope this helps! :D
Average rate of change over [1,5] = f(5) - f(1) / 5 - 1
= [(17-5^2) - (17-1) ] / 4
= (-8 - 16) / 4 = -24 / 4 = -6 Answer
