Answer: A,B and C

-6x-6=-6x-103
+6 both sides
-6x=103
divide -6
x=103/6
ONE SOLUTION

-103x-6=-6x-103
+6x both sides
-97x-6=-103
+6 both sides
-97x=-97
divide -97
x=1
ONE SOLUTION

-6x-6=103x-103
+6x both sides
-6=109x-103
+103 both sides
97=109x
divide 109
97/109=x
ONE SOLUTION

103x-6=103x-103
-103x both sides
-6=-103
NO SOLUTION

Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5).<br> A. -6<br> B. 6<br> C. 8
marta [7]

Answer:

A. -6

Step-by-step explanation:

f(x)=3x-1\\\\

In order to find f(-2) we will plugin x=-2

f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1

f(-2)=-7

g(x)=-x+6

In order to find g(5) we will plugin x=5

g(5)=-5+6

g(5)=1

f(-2)+g(5)\\=-7+1\\=-6

∴ f(-2)+g(5)=-6

<u>3, 5, 5, 6, 6, 6, 7, 7, 8, 8,</u> 8, <u>8, 8, 8, 9, 9, 10, 10, 10, 10, 11</u>

Median is 8

Lower half of the data is : 3, 5, 5, 6, 6, 6, 7, 7, 8, 8,

First quartile is the median of the lower half of the data=6+6 /2 =6

Upper half of the data is: 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

The Third quartile is the median of the upper half=9+10 / 2 = 9.5
