Answer:

(1/2)x - y = -2

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Equality Properties

<u>Alg I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Standard Form: Ax + By = C

Step-by-step explanation:

<u>Step 1: Define equation</u>

Slope-Intercept Form: 2 + (1/2)x = y

<u>Step 2: Find Standard Form</u>

  1. Rewrite:                                        y = (1/2)x + 2
  2. Subtract 1/2x on both sides:       y - 1/2x = 2
  3. Factor negative:                          -(1/2x - y) = 2
  4. Divide both sides by -1:               1/2x - y = -2

The temperature at 6.00 am was - 12 the temperature increased by 1/2 each hour for 6 hours what was the temperature in degrees F
Illusion [34]

Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = \dfrac12 degrees Fahrenheit

Temperature increase in 6 hours = 6\times\dfrac12=3\text{ degrees Fahrenheit}

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

= -12+3 degrees Fahrenheit

= -9 degrees Fahrenheit

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Point A is on a number line halfway between −17−17 and 55. Point B is halfway between point A and 0. What integer does the point
julia-pushkina [17]
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
         = 36

Now find B using midpoint formula:
B: (a+b)/2 
=36+0/2
=18

1. What is the difference between an exponential growth and exponential decay? 2. What is an example equation for expoential gro
den301095 [7]

Answer: see below

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

The standard form of an exponential equation is: y = a(b)ˣ    where

  • a is the initial value
  • b is the rate

<u>Growth:</u>

Exponential growth is where the final value (y) is greater than the initial value (a).

An example would be the spreading of a rumor:  

You tell 1 person (a = 1) who then tells 2 people each minute (b = 2).  How many people will they have spread the rumor to after 5 minutes (x = 5)?

y = 1(2)⁵

  = 32

<u>Decay:</u>

Exponential decay is where the final value (y) is less than the initial value (a).

An example would be the decrease of bacteria in a person:

A person has 100 bacteria (a = 1) who takes a pill that is supposed to cut in half the number of bacteria each hour (b = 1/2).  How many bacteria will the person have after 2 hours (x = 2)?

y=100\bigg(\dfrac{1}{2}\bigg)^2\\\\\\.\quad =100\bigg(\dfrac{1}{4}\bigg)\\\\\\.\quad = 25
