Make a table with the domain of {2,3,4,5,6} and draw a graph of the absolute value function y = 2|x-4| + 3.
Jet001 [13]

Answer:

<h2>In the attachment.</h2>

Step-by-step explanation:

|a|=\left\{\begin{array}{ccc}a&for\ a\geq0\\-a&for\ a

Put each value of x from the set {2, 3, 4, 5, 6}

to the equation y = 2|x - 4| + 3:

x = 2 → y = 2|2 - 4| + 3 = 2|-2| + 3 = 2(2) + 3 = 4 + 3 = 7 → (2, 7)

x = 3 → y = 2|3 - 4| + 3 = 2|-1| + 3 = 2(1) + 3 = 2 + 3 = 5 → (3, 5)

x = 4 → y = 2|4 - 4| + 3 = 2|0| + 3 = 2(0) + 3 = 0 + 3 = 3 → (4, 3)

x = 5 → y = 2|5 - 4| + 3 = 2|1| + 3 = 2(1) + 3 = 2 + 3 = 5 → (5, 5)

x = 6 → y = 2|6 - 4| + 3 = 2|2| + 3 = 2(2) + 3 = 4 + 3 = 7 → (6, 7)

Mark the points in the coordinates system.

The domain is only five numbers, therefore the graph of this function is only five points.

Members of a softball team raised $1513.50 to go to a tournament. They rented a bus for $961.50 and budgeted $46 per player for
aniked [119]

Answer: 1513.50=961.50+46x

The number of players the team can bring to the tournament = 12.

Step-by-step explanation:

Let x= the number of players the team can bring to the tournament.

Total money raised = Rent of bus + (Cost per player) (Number of players)

1513.50=961.50+46x\\\\\Rightarrow\ 46x=1513.50-961.50\\\\\Rightarrow\ 46x =  552\\\\\Rightarrow x=\dfrac{552}{46}\\\\\Rightarrow x=12

Hence, the number of players the team can bring to the tournament = 12.

The numbers 38 and 41 are rounded to the nearest ten and then multiplied to estimate the product. What is the best estimate of 3
Rudik [331]

Answer:

Jeez this is a big question

Step-by-step explanation:

1. if they are rounded to the nearest 10 that would mean that it is actually

40 * 40

40 * 40 is 1600. The answer for #1 is 1600

2. its just asking what 21 x3 is, 21x3 is 63

3. All you do for this is 20*23

20 * 23 is 460

4. 42 * 31 is 1302

5. 22 * 95 = 2090

6. You do 20x2 which is 40 and then you do 8x2 which is 16

Adding

then you have 40 + 16 = 56

Subtracting

40 - 16 = 24

Multiplying

40 * 16 = 640

Dividing

40/16 = 2.5

7. 33x2 is 66

8. 57* 4 is 228

9. 128 * 11 is 1408 but if you round the 11 to the nearest 10, that would be 10, then if you round the 128 to the nearest 10, that would be 130, and then 130 * 10 is 1300
