Sorry, I’m busy but I’ll help you with this one.

$18.50 x 30 = $555

100% - 15% = 85%

$555 / 100 = $5.55

$5.55 x 85 = $471.75

Find coordinates for x+5y=10 and 3x+5y=0. I need to know how to do this plz explain.
maks197457 [2]

Answer:

(-5,3)

Step-by-step explanation:

<em><u>Method</u></em>

There are several ways you can do this, but one of the best ways is to use a graphing coordinate calendar. The most popular one is Desmos Graphing Calculator. I've attached an image of my work below using the system.

<u><em>Answer</em></u>

As you can see, both equations intersect at a certain coordinate point. This coordinate point is the point you need for the answer. The intersection is (-5,3).

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!

Given the parent function of f(x) = x^(4, what change will occurr when the function is changed to f((1)/(2) x))
jarptica [38.1K]

Answer:

The graph of the function f( (1/2)x ) will expand across x-axis

Step-by-step explanation:

We have been given the function:

f(x) = x⁴

If we substitute x = (1/2)x into the given equation, we get:

f((1/2)x) = ( (1/2)x )⁴

We can simplify the equation

f((1/2)x) = = (1/2)⁴ x⁴

f((1/2)x) = = (1/16) x⁴

Graph of both of the functions is shown below. We can clearly see that that the graph of the function f((1/2)x) = = (1/16) x⁴ expands horizontally on x-axis as compared to the graph of f(x) = x⁴

A square has an area of 36 m2. The square is scaled in such a way that its area is increased by 28 m2. What is the approximate f
Naddika [18.5K]

Answer:

The length has increased by a factor of 4/3 or 1 1/3

Step-by-step explanation:

To find the initial length.: root 36.

Root 36 = 6

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:

6x = 8

x = 8/6 = 4/3

The length has increased by a factor of 4/3 or 1 1/3
