y=2x−15

4x+3y=−5


_________



4x+3(2x-15)= -5


4x+6x-45= -5


10x=-5+45


10x= 35


X=35/10


X= 3.5 or 3 and 1/2


Now solve for y

4x+3y=−5


4(3.5)+3y= -5


12.5+3y= -5


.40+3y= -5


3y= -5-0.40


3Y= -5.40


Y= -1.80


Answer (3.5, -1.80)

A line passes through the point (-4, -2) and has a slope of -5/2. Write an equation in slope- intercept form for this line.
kirill115 [55]

Answer:

<h2>           y = -⁵/₂x - 12 </h2>

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -⁵/₂

(-4, -2)    ⇒   x₀ = -4,  y₀ = -2

The point-slope form of the equation:

y + 2 = -⁵/₂(x + 4)

So:

y + 2 = -⁵/₂x - 10         {subtract 2 from both sides}

y = -⁵/₂x - 12             ←  the slope-intercept form of the equation

Answer:

see below

Step-by-step explanation:

That is a LOT of questions

complement angles add to 90    suppleent angles add to 180

9)  complement = 50   supplelement = 140

13)  compl = 40     suppl = 130  

14) comp = 45        supple = 135

I think you can do the rest, right?
