Answer:
x2+5x/2 -4
Step-by-step explanation:
f(x) = 2x+3 and g(x) = x^(2)+(x)/(2) - 7 , what is (f+g)(x)
x^2+5x/2-4
Answer:
Denominator for 2/5 is 5, and denominator for 13/16 is 16.
Answer:
Hence, the set that represent a negative linear association between x and y is:
Set A.
Step-by-step explanation:
We are given 4 sets of data as:
<u>Set A </u>
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
<u>Set B </u>
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11
<u>Set C </u>
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
<u>Set D </u>
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9
We are asked to determine the set which represent negative linear association between x and y?
- Clearly in Set B and Set D the values of y keeps on increasing as the value of x increases; hence they both represent a positive linear association between x and y.
- In set C the relationship is non-linear though it is negative.
- Clearly in Set A we could see that the the y is related to x as:
y=11-x or y= -x+11.
Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.
Hence, the set that represent a negative linear association between x and y is:
Set A.
Answer:
if it's me I would pick etherbc are d I holp it helps
Answer:
option B
Step-by-step explanation:
-4<x<-1 and 1<x<4 is the interval where y=g(x) <0
Option B, 2<x<3 is falling in this interval
