Answer:

im not sure of the answer but hopefully this will help

Step-by-step explanation:

basically the intervals in which its increasing and decreasing depend on the leading coefficient and the vertex

since this is opening up, the intervals will be

the function is increasing (x coord of vertex, infinity)

the function is decreasing (-infinity, x-coord of vertex)

How to find the coordinates?

zhenek [66]

The lower number of the fraction is the X value and since it's negative u go 3 to the right(if u loon at point T)and since it's a negative 4 on the top you go 4 down and if you would reverse it you would notice that 0|4 is 1 y value below the straight line so the coordinates are (3|5)

Simplify (2z^5)(12z^3)/4z^4

Sphinxa [80]

Answer:

$6z^{4}$

Step-by-step explanation:

Given in the question an expression,

$\frac{ (2z^5)(12z^3)}{4z^4}$

Step 1

Apply exponential "product rule"

$x^{m}x^{n}=x^{m+n}$

$\frac{ 12(2)z^5)(z^3)}{4z^4}$

$\frac{ (24)z^5)(z^3)}{4z^4}$

$\frac{ 24(z^{(5+3)})}{4z^4}$

$\frac{ 24(z^{8})}{4z^4}$

Step 2

Apply exponential " divide rule"

$\frac{x^{m}}{x^{n}}=x^{m-n}$

$\frac{24/4(z^{8})}{z^4}$

$\frac{6(z^{8})}{z^4}$

$\frac{6(z^{8-4})}{1}$

$6z^{4}$

Graph y = -1/3x + 3<br><br> (( if you could include a picture of the graph that would be great))

Kay [80]

A place I go to graph is go to desmos. It works well for this. All you have to do is snip the picture of your graph

Ba - ha = c <br> solve for a

PilotLPTM [1.2K]

Answer:

h = $\frac{c}{b-h}$

Step-by-step explanation:

Given

ba - ha = c ← factor out a from each term on the left side

a(b - h) = c ← divide both sides by (b - h)

a = $\frac{c}{b-h}$

Will do a brainly! 4/7=18/31.5

german

Answer:

True

Step-by-step explanation:

4 ÷ 7 = 0.5714
18 ÷ 31.5 = 0.5714
Because they are the same result, the two fractions are equal. Therefore, the equation is true.

I hope this helps!
