The price now is $55.3

30% of 79 is 23.7 and if you subtract that from 79, you get 55.3 which is what the price would be after the reduced percent.

The graph of this function is shifted 7 units right and shifted 5 units up.
mojhsa [17]
<h2><u>Graphing</u></h2>

<h3>The graph of this function is shifted 7 units right and shifted 5 units up.</h3>

<h3>f(x) = -2/3(x - 7)² - 5</h3>

  • True
  • False

<u>Answer:</u>

  • <u>False</u>

<u>Explanation:</u>

  • Why false? As I noticed, in the equation f(x) = -2/3(x - 7)² - 5, the vertex is (7, -5). The value of a, which is -2/3, is negative. So the graph opens downwards. The graph shifts 7 units to the right, which is correct, but graphing 5 units up is wrong. Why? 5 is negative, so it should be shifted 5 units down.

Help plz will give brainliest if you explain how u got the answer! PLZ!
sasho [114]

Answer:

2x-y=4

Step-by-step explanation:

y=mx+b

b is the y-intercept which is -4

y=mx-4

find m(slope)

(2,0) and (0,-4)

(-4-0)/(0-2)

-4/-2=2   m=2

y=2x-4

add 4 to both sides

y+4=2x subtract y

4=2x-y

It says write in standard form which looks like this: 3x + 5y = 4
