Why does the graph of a function shift left when K is positive and to the right when K is negative?

Sedaia [141]

Answer:

You can visualize this easily.

y=f(x+h)

Now if the argument of the function is taken as (x−h) the value of y will be f((x−h)+h)=f(x)

The function y acquires the value of f(x) at (x−h) amounting to a left shift.

Hope this makes things clear.

How do i cross multiply rational equations? EX: 6/x = 4/3

aliya0001 [1]

You would multiply 6 by 3 and x by 4. You would end up getting 4x = 18 and then you simplify that to get 9/2 or 4.5.

The linear scale factor of two shapes is 3:4. If the area of the smallest shape is 72^2 what is the area of the big shape?

Lorico [155]

Answer:

$\boxed{6912 units^2}$

Step-by-step explanation:

<em>Hey there!</em>

Well using the given ratio,

3:4

And the area of the small shape we need to do,

72*72 = 5184

Now we can make the following fractions,

$\frac{3}{4}$ = $\frac{5184}{x}$

Now we can solve,

3*x = 3x

4 * 5184 = 20736

3x = 20736

20736 / 3

x = 6912

So the area of the bigger shape is 6912 units^2

<em>Hope this helps :)</em>

What is the slope of the equation-3=-4(x-5)

scZoUnD [109]

You need to simplify it first.
$-3=-4(x-5)$
Use distribution
$-3=-4x+20$
y=mx+b
m=slope
your slope is -4 :)
