Answer:
The required linear function is: f(x) = 
Step-by-step explanation:
We are given that f(x) is a linear function and it takes the value 9 when x = 2 and 14 when x = -1.
Now the general form of any linear function is: f(x) = ax + b.
Substituting these values in the general form we get:
f(2) = 9 = 2a + b
f(-1) = 14 = -a + b
Solving these two equations we get:
b = 37/3
Substituting this in the second equation to find 'a'.
a = -5/3
Therefore, the function f(x) = 
x + 
.
I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.
a.
b. I will solve your system using substitution.
<span>Step 1: Solve </span>
for x
(add -y for both sides)
<span>Step 2: substitute </span>
for x in
<span>
</span>
(simplify both sides of the equation)
(add -425 to both sides)<span>
</span>
y=200
step 3: substitute 200 for y in
c. Already answered with the picture that is attached.
d. Gavin earned 225 dollars while Seiji earned 200 dollars.
One possible equation would be 20 = 1/2x + 4.
Let x be the number of students in his homeroom. 1/2x is half of the students in his homeroom. Four more than 1/2 would be 1/2x + 4. This is, or equals, the 20 students that have tickets.
Answer:
From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).
