Answer:
Step-by-step explanation:
the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.
50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.
Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.
this is the formula that can help with any percentage math problem:
The percentage of something ÷ 100% = the number you are looking for ÷ the total
in our case:
40÷100 = x (because it is the unknown term)÷60
from here you cross multiple getting
2400÷100x
which equals
24
now we have to add Vicky's and Iverson's voter
24 + 30= 54
60-54=6
6 students did not participate
we are given

Since, we have to find inverse of this function
step-1: we set f(x)=y

step-2: switch x and y

step-3: Solve for y

now, we can use quadratic formula

The first one you pick goes with 2 and the exponent -5 on the top
The second one you pick goes into I think into the 2 and exponent -32
And the third one you pick goes into the 1
The last one matches with the last one

Answer:
y =
x + 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
To calculate the slope use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)
m =
=
, hence
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (5, 7 ), then
7 =
+ c ⇒ c = 7 -
= 
y =
x +
← equation in slope-intercept form
