Write an equation in point-slope form of a line that goes through the points (1,4) and (3,-10). Do not use any spaces in your an
olasank [31]

Answer:

y-4=-7(x-1) OR y-(-10)=-7(x-3)

Step-by-step explanation: The point-slope form is y_-y_{1}=m_(x_-x_{1})

In slope-intercept form, the equation would be y = -7x + 11

You could find the slope by using the slope equation, \frac{y_{2} -y_{1} }{x_{2} -x_{1} }.

Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.

• Malik Montez's savings account has a principal of $1,640. It earns 6 percent interest a
jekas [21]

Answer:

The amount at the end of second quarter is $1842.704

Step-by-step explanation:

Given as :

The principal in saving account = $1640

The rate of interest = 6 % compounded quarterly

The time period = 6 months

Now,<u> from compounded method</u>

The amount at the end of first quarter = A_1 = principal + 6 % of principal

I.e  A_1 = $1640 + 6 % × $1640

Or, A_1 = $1640 + $ 98.4

∴ A_1 = $1738.4

Again ,

The amount at the end of second quarter = A_2 = A_ + 6 % of  A_1

I.e  A_2 = $1738.4 + 6 % × $1738.4

Or, A_2 = $1738.4 + $104.304

∴ A_2 = $1842.704

So, The amount at the end of second quarter =  A_2 = $1842.704

Hence , The amount at the end of second quarter is $1842.704 Answer
