Answer:
The one that gives us the fastest y-intercept is "b". The coordinates are (0,15).
Step-by-step explanation:
In order to check which form gives us the fastest y-intercept value, let's apply x = 0 in all three of them and check how many operations we need to do to get our desired results.
a) f(x) = -3*(x - 2)² + 27
f(0) = -3*(0 - 2)² + 27
f(0) = -3*(4) + 27
f(0) = -12 + 27
f(0) = 15
b) f(x) = -3*x² + 12*x + 15
f(0) = -3*(0)² + 12*(0) + 15
f(0) = 15
c) f(x) = -3*(x + 1)*(x - 5)
f(0) = -3*(0+1)*(0-5)
f(0) = -3*(-5)
f(0) = 15
The fastest one is "b". Since it is in the standard second degree equation form "a*x² + b*x + c", we could have checked immediately by the value of "c".
The y-interecept is (0,15).
Answer:
y < 8
Step-by-step explanation:
First, distribute that -3 over (3y + 4), obtaining -9y - 12 < -12y + 12.
Next, add 12y to both sides, obtaining 3y - 12 < 12, or 3y < 24
Then y < 8 must be true.
Answer:
<em>Student C </em>
Step-by-step explanation:
<em>* Student C *</em>
If we were to take a look at the problem we would see that the greatest difference would be the greatest difference from 0, either positive of negative;
Student A: 1 from 0,
Student B: 0 from 0,
Student C: 3 from 0,
Student D: 2 from 0
<em>As we see from the results, Student C has the greatest difference from before</em>
