Answer:

C. It is shifted 5 unit(s) up.

Step-by-step explanation:

The y-intercept of the first equation is –5. The y-intercept of the second equation is 0. This means that it moves up by 5 units.

hello could you please help me with this math problem with full explanation which I am unable to solve? Thanks.
neonofarm [45]

Answer:

8 / sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan A = BC / AC

tan 30 = BC / 8

8 tan 30 = BC

8 * sqrt(3)/3 = BC

8/3 sqrt(3) = BC

Can someone plz help me solved this problem! I’m giving you 10 points! I need help plz help me! Will mark you as brainiest!
Kobotan [32]

Answer:  $2 or $9

<u>Step-by-step explanation:</u>

Revenue (R) = $1800 , x = 1100 - 100p

R = xp

1800 = (1100 - 100p)p             <em>substituted x with 1100 - 100p</em>

1800 = 1100p - 100p²             <em>distributed p into 1100 - 100p</em>

100p² - 1100p + 1800 = 0       <em>added 100p² & subtracted 1100p</em> on both sides

     p² - 11p + 18 = 0                <em>divided both sides by 100</em>

(p - 2) (p - 9) = 0                     <em>factored quadratic equation</em>

p = 2  p = 9                         <em>applied Zero Product Property to solve for p</em>

Equality Properties

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

[Standard Form]   -5x - 4y = -12

<u>Step 2: Rewrite</u>

  1. Add 5x to both sides:                    -4y = 5x - 12
  2. Divide -4 on both sides:                y = -5/4x + 3

<u>Step 3: Identify</u>

<em>Break apart the function.</em>

Slope <em>m</em> = -5/4

y-intercept <em>b</em> = 3
