I can help! As you may know y = mx+b is our slope-intercept equation, so let's plug some numbers into where they need to be.


The easiest part is finding B (the y-intercept) which is -3. Now, our equation is y = mx+(-3) or, as we will properly write it, y = mx-3


Let's find the slope (m) now! Let's take the first coordinate given (0, -3) and count the rise over the run that takes us to the next coordinate (2, 1)


Rise (going up) is four, and the run (across) is two. Making our slope 4/2, which is an improper fraction, so let's simplify it to 2. Now, we have our "m,"


That's all you need for this equation, since the y and x are left as they are.


y = 2x-3 is your answer

Answer:

y = 2x-3

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/(x2-x1)

   = (1--3)/(2-0)

   = (1+3)/(2-0)

   =4/2

   = 2

The y intercept (where x=0) is -3

We can use the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = 2x-3

Answer:

The population will be 240,116

Step-by-step explanation:

Exponential growth can be represented by the expression:

P(t) = P_i\,(1+r)^t

where:

P(t) is the population at time (t)

P_i is the initial value of the population

"r" is the annual rate of growth (written in decimal form)

and "t" is the time in years.

Therefore in this situation, P(16) is what we want to find [the population after 16 years]

the initial population P_i is 110,000

the rate of growth is 0.05 [decimal form of 5%]

and t is 16 years.

Replacing all these in the given functional form gives:

P(t) = P_i\,(1+r)^t\\P(16)=110000\,(1+0.05)^16\\P(16)=240116

Suppose there were m married couples, but that d of these 2m. people have died, Regard the d deaths as striking the 2m people at
iren2701 [21]

The function that represents surviving people are X = 2m - d

Given that there are m married couples and d of the 2m of these couples have died, the total people that remain is expressed as:

Total people remaining = Total married couple - those that died

Total married couple = 2m

Total people that died = d

Taking the difference to get the remaining people;

Total people remaining = 2m - d

Hence the function that represents surviving people are X = 2m - d

1. Mrs. Verner's class has
Gemiola [76]

Answer:

46.7%

Step-by-step explanation:

Given:

Total number of students in Mrs. Verner's class = 15

Number of girls = 8

To find: percentage are boys

Solution:

Percentage of boys = ( Number of boys / Total number of students ) × 100

Number of boys = Total number of students - Number of girls = 15 - 8 = 7

So,

Percentage of boys =  × 100 = 46.7%

You work 4 hours on Monday, 4.5 hours on Tuesday, 7.25 hours on Thursday, and 12 hours on Saturday. If you get paid $11.52 per h
ch4aika [34]

Answer:

$319.43

Step-by-step explanation:

Monday= 4 * $11.52=  $46.08

Tuesday= 4.5 * $11.52= $51.84

Thursday= 7.25 * $11.52= $83.27

Saturday= 12 * $11.52= $138.24

When you add all of those together you get $319.43

hope this helped (:
