Simplify:
Serga [27]

Answer:

(a) 16-2x

(b)-x-2 or x+6

(c)

Step-by-step explanation:

(a)

|6-x|+|x-10|,

|4-x|=4-x,so x<4

|2-x|=x-2=-(2-x)

2-x<0

2<x

or x>2

2<x<4

so |6-x|=6-x,in 2<x<4

|x-10|=-(x-10),in 2<x<4

|6-x|+|x-10|=6-x-(x-10)=6-x-x+10=16-2x

(b)

2-|2-|x-2||,if x<-2

|x-2|=-(x-2) if x<-2

=2-|2-{-(x-2)}|

=2-|2+x+2|

x<-2

x+2<0

=2-|x+4|

=2-(x+4),if x>-4,or -4<x<-2

=2-x-4

=-x-2

if x<-4

then |x+4|=-(x+4)

2-|x+4|=2-{-(x+4)}

=2+x+4

=x+6

Which point is an x-intercept of the quadratic function<br> f(x) = (x – 8)(x + 9)?
max2010maxim [7]

x-intercept means f(x) = 0

(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9

There are two points which are x-intercepts. They are (8,0) and (-9,0).

Chef Rita Is cooking for a Sunday brunch.She knows that 22 pancakes can feed 8 people.She is wondering how many people she can f
AlexFokin [52]

Answer:

Chef Rita can feed 20 people with 55 pancakes.  

Step-by-step explanation:

We can solve this problem using equivalent ratios.  Since we know that Chef Rita can feed 8 people with 22 pancakes, we can set up the ratio:

\frac{22pancakes}{8people}=\frac{22}{8}

To solve how many people she would be able to feed with 55 pancakes, we can set ratios equal to each other and solve for 'x' which is the number of people.  

\frac{22}{8}=\frac{55}{x}

We can see what factor we multiply 22 by to get 55 and then we multiply the denominator by the same factor to get our equivalent ratio.  55 ÷ 22 = 2.5.  So, 8 x 2.5 = 20 people.
