Write the equation of a line that is perpendicular to y=3x-2 that passes trough the point (-9,5)

ElenaW [278]

$\huge\boxed{y-5&=-\frac{1}{3}(x+9)}$

First, we'll find the slope of the new line. The first line has a slope of $3$ . Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by $-1$ ) to get $-\frac{1}{3}$ for the new slope.

Then, we'll use the point-slope form to make the new equation, where $m$ is the slope and $(x_1,y_1)$ is a point on the line:

$\begin{aligned}y-y_1&=m(x-x_1)\\y-5&=-\frac{1}{3}(x-(-9))\\y-5&=-\frac{1}{3}(x+9)\end{aligned}$

A family is thinking about buying a new house

Rom4ik [11]

Answer:

a.) 1908.30

b.) 96373.15

c.)302491.15

unrounded answers below

Step-by-step explanation:

The amount that is to be loaned out is 380000-110000=270000

The effective montly rate is .07/12=.005833333

a.)

$270000=x(\frac{1-(1+.005833333)^{-(25*12)}}{.005833333})=1908.303833$

b.)

use what is called the prospective method (the outstanding loan balance at time n is equal to the present value of the remaining payments)

$1908.303833(\frac{1-(1+.005833333)^{-(25*12-20*12)}}{.005833333})=96373.14775$

c.)

total paid= 1908.303833*12*25=572491.1499

amount of loan: 270000

Total interest paid:

572491.1499-270000=302491.1499

Which is the smallest number? 2.07,2.7,2.4,2,2.04

Natasha2012 [34]

I believe it is 2 because, 0.4 is added on to 2. 2.7 is basically 2.70 making it 0.70 bigger than 2. I hope this helped

Which equation is in slope intercept form and represents a line with slope 0 through the point (2,3)

Neko [114]

The slope is m = 0 and the line goes through the point (x,y) = (2,3). So x = 2 pairs up with y = 3.

Plug m = 0, x = 2, y = 3 into the equation below. Then solve for b
y = mx+b
3 = 0*2+b
3 = 0+b
3 = b
b = 3

So if m = 0 and b = 3, then
y = mx+b
y = 0*x+3
y = 0+3
y = 3
is the equation of this line. This line is completely horizontal going through points like (0,3), (1,3), (2,3), etc. Every point on this line has a y coordinate of 3. The x coordinate can be any number you want.

Answer: Choice C) y = 3
