Use the coordinate of the labeled point to find a point-slope equation of the line

Ray Of Light [21]

Well since the line is headed to the left side, you know it has a negative slope, so B and C can be crossed out. Then, you know that point-slope form is written as y - y1 = m (x - x1)

So, you just plug in the numbers given on the graph, (4,-2)

You should come out with y + 2 = -2 (x - 4)

And that's the equation of the line in point-slope form!!! :)

Hope it helped and you understand it better!

D.) y + 2= -2 (x - 4)

If $10,500 is borrowed for 5 years at an annual simple interest rate of 1.73%, how much interest will be paid if the entire loan

Anvisha [2.4K]

Answer:

Step-by-step explanation:

So, yearly $2100 is paid, plus the 1.73% interest, so 1.73% interest is $2136.33every year interest stacks on itself so youll take 1.73% of the year 1 total with interest.

Year 1 total: $2136.33

Year 2 total:$2173.29

Year 3 total:$2210.89

Year 4 total:$2249.14

Year 5 total:$2288.05

Total Paid After 5 years:$11057.70

Year 1 total interest:$36.33

The number n of people using the elevator in an office building every hour is given by n = t2 − 10t + 40. In this equation, t is

Morgarella [4.7K]

Answer:

The number of persons using the elevator at any hour is never going to be less that 15.

Step-by-step explanation:

To solves this you have to suppose that there are at least 15 persons on the elevator, and the equation is converted into an inequation:

$t^2-10t+40$

Now you transform the inequation back to an equation to solve it:

$t^2-10t+25=0$

You need to know if there is any negative solution for the equation, to do this you can use the discriminant for a quadratic equation:

$D=b^2-4ac$

In this case, you have a=1, b=-10, c=25

$D= (-10)^2-4(1)(25)\\D=0$

Since the discriminant is 0 and a<0 the equation always is going to be positive. Therefore, the number of persons using the elevator at any hour is never going to be less than 15.
