Answer:

f(x)=-2*(x-3)+5 when x<u><</u>3

g(x)=x(x-3)+5 when x>3

Step-by-step explanation:

|   | is absolute function meaning the value must be larger than or equal to zero.

So | x-3 | = -(x-3) when x<u><</u>3

f(x)=-2*(x-3)+5 when x<u><</u>3


| x-3 | = (x-3) when x>3

g(x)=2*(x-3)+5 when x>3

Answer:

f(x) = -2( x - 3) + 5, x \leq 3\\\\g(x) = 2(x-3)+5, x > 3

Step-by-step explanation:

turning pt of the abs fn |x-3| is at x=3

2|x-3|=-2(x-3), x\leq 3\\\\2|x-3|=2(x-3), x>3

so

f(x) = -2( x - 3) + 5, x \leq 3\\\\g(x) = 2(x-3)+5, x > 3

Need help what are the classifications of each system
ratelena [41]
You can graph them on Desmos, then use this attachment to find out the classification.

In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.

In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.

In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

g100num [7]

We are told that the children from a football club are put into rows in the sports hall. When put into rows of 9 children there are 2 children left over. When put into rows of 12 children there are 2 children left over.

We will find least number of children in football club by finding LCM of 9 and 12.

Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63,...

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...

We can see that least common multiple of 9 and 12 is 36.

We are told that 2 children left over from putting them into 9 and 12 children per row. To find least number we will add 2 to 36.

9\cdot4+2=36+2=38

12\cdot3+2=36+2=38      

\text{Least number of children in football club}=36+2=38

Therefore, the least number of children in the football club is 38.

Please help, love you
ExtremeBDS [4]

Answer:

162

Step-by-step explanation:

Note that you can split the given shape into a triangle and a rectangle.

Area of rectangle = base x height

base = 12

height = 9

Plug in the corresponding numbers into the corresponding variables:

Area of rectangle = 12 x 9

                             = 108

Area of triangle = (base x height)/2

base = 12

height = 9

Area of triangle = (12 x 9)/2

                          = (108)/2

                          = 54

Next, add the two areas together to get the full area:

108 + 54 = 162

162 is your answer.
