[30 POINTS] Please help!!!

Len [333]

Answer:

Part 1) $y=1.5x+5$

Part 2) $y=-(2/3)x-(11/3)$

Part 3) $y=0.25x+2.75$

Part 4) $y=-2x+5$

Part 5) $y=0.5x-1$

Part 6) The graph in the attached figure

Step-by-step explanation:

Part 1) we have

$m=3/2=1.5$

$point(-2,2)$

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

substitute

$y-2=1.5(x+2)$

$y=1.5x+3+2$

$y=1.5x+5$

Part 2) we know that

If two lines are perpendicular

then

the product of their slopes is equal to minus one

so

$m1*m2=-1$

the slope of the line 1 is equal to

$m1=1.5$

Find the slope m2

$1.5*m2=-1$

$m2=-2/3$

Find the equation of the line 2

we have

$m2=-2/3$

$point(-7,1)$

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

substitute

$y-1=(-2/3)(x+7)$

$y=-(2/3)x-(14/3)+1$

$y=-(2/3)x-(11/3)$

Part 3) we have

$m=1/4=0.25$

$point(1,3)$

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

substitute

$y-3=0.25(x-1)$

$y=0.25x-0.25+3$

$y=0.25x+2.75$

Part 4) we have

$m=-2$

$b=5$ -----> y-intercept

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

substitute the values

$y=-2x+5$

Part 5) we have that

The slope of the line 4 is equal to $-2$

so

the slope of the line perpendicular to the line 4 is equal to

$-2*m=-1\\m=(1/2)=0.5$

therefore

in this problem we have

$m=0.5$

$point(-2,-2)$

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

substitute

$y+2=0.5(x+2)$

$y=0.5x+1-2$

$y=0.5x-1$

Part 6)

using a graphing tool

Can someone help this is due tomorrow!!

Answer:

angle 1 = 100 degrees

angle 2 = 53 degrees

Step-by-step explanation:

diagonals of a rhombus bisect angles so angles 2 and 3 are both 53

angle 1 can be found by adding 37 and 53 and deducting that sum from 180

X+9/x^3-9x^2+15x+25<br> how do I solve this

mezya [45]

$\frac{x + 9}{x^{3} - 9x^{2} + 15x + 25}$
$\frac{x + 9}{x^{3} - 10x^{2} + x^{2} + 25x - 10x + 25}$
$\frac{x + 9}{x^{3} - 10x^{2} + 25x + x^{2} - 10x + 25}$
$\frac{x + 9}{x(x^{2}) - x(10x) + x(25) + 1(x^{2}) - 1(10x) + 1(25)}$
$\frac{x + 9}{x(x^{2} - 10x + 25) + 1(x^{2} - 10x + 25)}$
$\frac{x + 9}{(x + 1)(x^{2} - 10x + 25)}$
$\frac{x + 9}{(x + 1)(x^{2} - 5x - 5x + 25)}$
$\frac{x + 9}{(x + 1)(x(x) - x(5) - 5(x) + 5(5)}$
$\frac{x + 9}{(x + 1)(x(x - 5) - 5(x -5))}$
$\frac{x + 9}{(x + 1)(x - 5)(x - 5)}$
$\frac{x + 9}{(x + 1)(x - 5)^{2}}$
