Complex roots occur when b^2 - 4ac is negative.
So we have (-6)^2 - 4.1.k < 0
-4k < - 36
k > 9
answer
is -7
explained
because f(x)=3x+1,for f (-2/3)= -7
1. The counterclockwise rotation by 90° about the origin has rule:
(x,y)→(-y,x).
Then
(-3,-1)→(1,-3).
2. Translation 4 units up has rule:
(x,y)→(x,y+4).
Then
(1,-3)→(1,1).
Answer: after composition of transformations the image point has coordinates (1,1).
Answer:
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
Explanations:
Number of snicker bars = 6
Number of cookies = 5
Total = 6 + 5 = 11
a) Ratio of snickers to cookies = 6 : 5
b) Ratio of cookies to snickers = 5 : 6
c) Ratio of cookies to total = 5 : 11
The larger number is 120 and the smaller number is 80
