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).
So pemdas
square root of 9 means 9^(1/2) so it counts as an exponent so
9=3 times 3 so square root of 9=3
square root of 25
do pemdas so exponents before division
25=5 times 5 so
square root of 25==5 so
3/5=0.6
Answer:
12x - 9y
Step-by-step explanation:
According to the distributive property:
3(4x - 3y) =
3*4x - 3*3y =
12x - 9y
Answer:
17x + 16
-7x - 1
-6x - 13
2x + 3
2x - 1
9x + 8
2x - 13
10x - 11
- 8
Step-by-step explanation:
Did this all in my head so apologies if its incorrect! Mostly just collecting like terms and distributive property.
Answer:
C- Inverse
Step-by-step explanation:
Logarithmic example:
log₆ of 6, the answer is 1.
Exponential example:
= 6
These are inverses
hope this helps :)
