Use the graph to find the constant then explain what the points

Answer:

So, Y (the up and down part of the graph) equals K (The constant of proportionality, you get it by dividing Y by X), times X (the side by side part of the graph.)

Graph 3x+y=-10 -x+3y=0

nikdorinn [45]

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the equations in the standard form. Convert to the slope-intercept form:

$3x+y=-10$ subtract 3x from both sides

$y=-3x-10$

$-x+3y=0$ add x to both sides

$3y=x$ divide both sides by 3

$y=\dfrac{1}{3}x$

-----------------------------------------------------

We need only two points to plot a graph of each function.

$y=-3x-10$

for x = 0 and for x = -3:

$y=-3(0)-10=0-10=-10\to(0,\ -10)\\\\y=-3(-3)-10=9-10=-1\to(-3,\ -1)$

$y=\dfrac{1}{3}x$

for x = 0 and for x = -3:

$y=\dfrac{1}{3}(0)=0\to(0,\ 0)\\\\y=\dfrac{1}{3}(-3)=-1\to(-3,\ -1)$

Look at the picture.

Answer:

(b) 3h^-8·k^10

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

$\dfrac{15h^{-4}k^{15}}{5h^4k^5}=\dfrac{15}{5}h^{-4-4}k^{15-5}=\boxed{3h^{-8}k^{10}}$

(2x-4)/(x-5)=0 show work (and please explain)

tensa zangetsu [6.8K]

2x-4/x-5 = 0 (Determine the defined range)
x \neq 5
2x-4 = 0 (Move constant to the right side and change its sign)
2x=4
x=2, x \neq 5 (Check if the solution is in the defined range)
x=2
