So you know that they pay $1320 on tax per year, but you want to know how much tax they pay per month. So we divide this number by 12 which is how many months are in one year. That gives you $110 they are spending on tax per month. Their monthly house payment is $862, so we add in the tax. $862+$110. This gives you $972 which is your final answer.

Sarah is 3 years older than nine times Mario's age. In 10 years, she will be 1 less than triple his

Natasha2012 [34]

Answer:

3(9m + 13) - (m + 10) = 1

Step-by-step explanation:

Here, we want to write an equation we can use to find the age of Mario.

Let the present age of Mario be M

Age of Sarah is 3 years older than 9

times Mario’s age

Mario’s age is thus;

9m + 3

In ten years, she will be 1 less than triple his age

In 10 years time, sarah age will be 9m +

3 + 10 = 9m + 13

Mario age will be m + 10

Mathematically;

3(9m + 13) - (m + 10) = 1

Find the x-intercepts/roots of the polynomial function. Also, identify the degree of the polynomial

Mrac [35]

Answer:

Step-by-step explanation:

roots=-2,-1,1,3

critical points=(-1.5,-3),(0,6),(2,-13)

absolute minimum=-13

End behavior :approaches +infinity

Relative max=6 at (0,6)

Relative min. =-3 at (-1.5,-3)

and -13 at (2,-13)

interval of increase=(-1.5,0)∪(2,∞)

interval of decrease=(-∞,-1.5)∪(0,4)

roots=-1,2

critical points=(0.5,10.5),(4,-10.5)

Abs.max/abs.min=not defined

End behavior:-∞ to +∞

Relative max=10.5

Relative min=-10.5

interval of increase=(-∞,0.5) ∪ (4,∞)

interval of decrease=(0.5,4)
