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:
B. $2,565
Step-by-step explanation:
Answer:
7/4 yard
Step-by-step explanation:
36 is a suitable common denominator for expressing these fractions. All measures are in yards.
2/3 + 4/9 + 23/36 = (12·2)/(12·3) + (4·4)/(4·9) + 23/36
= 24/36 + 16/36 + 23/36
= 63/36 = (9·7)/(9·4)
= 7/4 = 1 3/4 . . . . . yards
I think the number is 290.
*There's 2 hundreds
*9 is 9 more than 0
I think it’s A and B because on the top where is is 24 is M and the bottom is 25 which is L
