Evaluate the function represented by the graph for f(-2).

Evaluate The Function Represented By The Graph For F(-2).

Answers

Answer 1

Answer:

f(-2) = 2

Step-by-step explanation:

The question is asking you to find the y value when the x value is -2. When observing the graph, we can see when the x value is -2, the y value is 2. Therefore, f(-2) = 2.

Answers

Answer:

AD=35

Step-by-step explanation:

The difference between FJ-GH is equal to the difference between EK-FJ

Lets call this difference "D"

so

(7x+2)-(8x-7)=D    

simplifying

7x+2-8X+7=D

-x+9=D

(10x-1)-(7x+2)=D

simplifying

10x-1-7x-2=D

3x-3=D

now D=D so

-x+9=3x-3

12=4x

x=3

solving each known line equation for x:

8(3)-1=17

7(3)+2=23

10(3)-1=29

The line gets longer each time by 6

AD=EK+6=35

1. Find a line that is parallel to f(x) = 2x +3 and passes through (0,-4).

2. Find through line that is perpendicular to f(x) = 2x+3 and passes through (0,-4)

Answers

Answer:

1)The equation of the Parallel line is 2x -y -4=0

2) The equation of the perpendicular line of the given line x+2y+8=0

Step-by-step explanation:

Step(i):-

Given function f(x) = 2x+3 and passes through (0,-4)

Let y =f(x) = 2x+3

    y = 2x+3

⇒ 2x -y +3=0

The equation of the parallel line of the given line 2x - y +k =0

This line is passes through the point (0,-4)

⇒ 2 (0) -(-4)+k=0

            4 +k=0

        ⇒    k =-4

The equation of the Parallel line is 2x -y -4=0

2)

Step(ii):-

Given function f(x) = 2x+3

Let y = 2 x + 3

 2x - y +3=0

The equation of the perpendicular line   bx -ay +k=0

The equation of the perpendicular line of the given line -x-2y +k =0

This line is passes through the point (0,-4)

⇒  (0) -2(-4)+k=0

            8 +k=0

        ⇒    k =-8

The equation of the perpendicular line of the given line -x-2y -8 =0

The equation of the perpendicular line of the given line x+2y+8=0

A certain prescription has a 0.15 cc dosage tolerance factor in its liquid form. If a doctor prescribes 2.4 cc of medication, find the upper and lower limits of the amount of medication that should be given to the patient. Do not round your answer.

Answers

Answers:

Upper Limit = 2.55 cc

Lower Limit = 2.25 cc

cc stands for "cubic centimeters".

==========================================

Explanation:

The tolerance tells us how much we can go over or under our target. It's our margin of error. We add and subtract the tolerance (0.15) from the target we're trying to aim for (2.4)

So the lowest dosage allowed is 2.4-0.15 = 2.25 cc

The highest dosage allowed is 2.4+0.15 = 2.55 cc

The upper limit is 2.55 cc while the lower limit is 2.25 cc

On a number line, we would find that 2.4 is at the midpoint of 2.25 and 2.55; so its at the center of those lower and upper bounds. The distance from the center to each endpoint is the same. That distance would be the tolerance 0.15

Answers

Answer:

Larry places 19 puzzles

Step-by-step explanation:

Step one:

given data

let the number of puzzles Larry places be x

and let the number of puzzles Drew places be y

so

y=3x-11

Step two:

We are told that Drew places at least 10

so for x= 10

y= 3*10-11

y=30-11

y=19
