Answer: The answer is 40 minutes

Step-by-step explanation:

He only read 20 minutes last saturday so that means he needs to read 10 extra minutes so he can make up for the minutes he lost. Add 10 to 30 minutes and you get 40 minutes.

What is the vertex of the absolute value function defined by ƒ(x) = |x + 2| + 4?
Marrrta [24]

Answer:

C. (-2,4)

Step-by-step explanation:

We have been given a function f(x)=|x+2|+4 and we are asked to find the vertex of our absolute value function.

The rules for the translation of a function are as follows:  

f|x-h|=\text{Graph shifted to right by h units}

f|x+h|=\text{ Graph shifted to left by h units}

f|x|+h=\text{ Graph shifted upward by h units}

f|x|-h=\text{ Graph shifted down by h units}

Upon comparing our absolute function with above transformations we can see that our function is shifted to two units right of the origin(0,0) so x coordinate of our absolute function will be -2.

Our function is shifted upward from origin by 4 units, therefore, y-coordinate of our absolute value function will be 4.

f(x)=|x--2|+4

Therefore, the vertex of our absolute value function will be on point (-2,4) and option C is the correct choice.

Find the perimeter of a triangle garden that measures 10 feet by x feet by (2 x+7) feet . Use p=a+b+c
tigry1 [53]

P = 10 + x + 2x + 7

= (10 + 7) + (x + 2x)

= 17 + 3x

Therefore, the perimeter is 17 + 3x feet.
