line passes through the point (-3,-4) and its y-intercept is (o, -9). What is the equation of the line that is parallel to the f

12345 [234]

Answer:

$y=-\frac{5}{3}x-2$

Step-by-step explanation:

The first line has a slope of -5/3 found using the points in the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1} =\frac{-9--4}{0--3}=\frac{-9+4}{0+3}=\frac{-5}{3}$

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form $y-y_1=m(x-x_1)$ .

$y--7=-\frac{5}{3}(x-3)\\y+7 = -\frac{5}{3}(x-3)\\y=-\frac{5}{3}x + 5 -7\\y=-\frac{5}{3}x-2$

Determina la suma de las siguientes progresiones los primeros 18 términos de la progresión aritmética: an = -{4, 12, 20, 28, 36,

Anuta_ua [19.1K]

Hello,
let
t=(-4)+(-12)+(-20)+(-28)+(-36)+....=-(4+12+20+28+36+...)=-s

$a_{1}=4=-4+1*8$
$a_{2}=12=-4+2*8$
$a_{3}=20=-4+3*8$
$a_{4}=28=-4+4*8$

...
$a_{18}=?=-4+18*8=140$

$a_{i}=-4+i*8$

$s=\sum_{i=1}^{18} (-4+i*8)=\sum_{i=1}^{18} (-4)+\ 8*\sum_{i=1}^{18}(i)\\\\=(-4)*18+8*(1+2+3+4...+18)\\\\=-72+\frac{(1+18)*18}{2}\\\\=-72+171=99$

$\boxed{\ t=-99}$

Step-by-step explanation:

Hey There!

To find the area of a triangle we divide the product of the height and base by 2

6x10=60

60/2=30

the area of the triangle is 30 :)
