Answer:

18 and 40

Step-by-step explanation:

Let x be the age of Claire and y the age of her mother

Claire's mother is 4 years more than twice Claire's age

  • y = 2x+4

The sum of their ages are is 58

  • x+y = 58

the system is:

\left \{ {{y=2x-4} \atop {y+x=58}} \right.  

Multiply (y+x = 58) by -1 and then add it to (y = 2x+4) to eliminate y

  • -y-x = -58
  • -y-x+y = 2x+4-58
  • -x -2x = -54
  • -3x = -54
  • x = 54/3
  • x = 18

y= 58-18 = 40

so claire's mother is 40 years old and claire is 18

Use the given parent function f(x)=|x| to graph g(x)=|x+2|-4. use the ray tool and select two points to graph each ray. ​
marin [14]

Shown in the attached figure

<h2>Explanation:</h2>

The absolute value function is a function that takes the shape of a V. The pattern of the absolute value function is:

f(x)=\mid x \mid

So we need to use this function in order to obtain:

g(x)=\mid x+2 \mid -4

Recall that to translate a function vertically, we use the following rule:

g(x)=f(x)+k \\ \\ \bullet \ If \ k>0 \ the \ graph \ of \ f(x) \ is \ translated \ k \ units \ up \\ \\ \bullet \ If \ k

And to translate a function horizontally, we use the following rule:

g(x)=f(x+c) \\ \\ \bullet \ If \ c>0 \ the \ graph \ of \ f(x) \ is \ translated \ c \ units \ to \ the \ left \\ \\ \bullet \ If \ c

Since:

c=2>0 \  and \ k=-4

Then:

<em>g(x) is the translation of f(x) 2 units to the left and 4 units down</em>

F(x) = -1/3x find the average rate of change of f from -2 to 2
Bas_tet [7]
Average rate=(change in y)/(change in x)

if f(x)=-x/3

r=( f(2)-f(-2) )/(2--2)

r=(-2/3-2/3)/(2+2)

r=(-4/3)/4

r=-4/12

r=-1/3

For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
