Given the two functions below with their provided domain, determine which function to substitute into and find the value of f(-3).

Provide your numeric answer as well as a detailed response on how you determined your answer and why you believe it is correct.

f(x) = 2x − 5 if x ≤ −3 OR f(x) = −3x + 4 if x > −3

Answer:

Part A: 31000 + 3000x = 38000 + 2000x; Part B: 7 years.

Step-by-step explanation:

x = number of years since start

For Company A, we have that salaryA(x) = 31000+3000x,

For Company Part B: salaryB(x) = 38000+2000x

We want x such that salaryA(x) = salaryB(x).

Thus,

31000 + 3000x = 38000 + 2000x (Answer to part A)

Subtracting 31000 from both sides of the equation implies that:

3000x = 7000 + 2000x.

Subtracting 2000x from both sides implies that:

1000x = 7000.

Then, dividing both sides of the equation by 1000 yields:

x = 7 years (Answer to part B)

Answer:

Yes, because each input value corresponds to exactly one output value.

Answer:

81% of the balls are red

Step-by-step explanation:

If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball

18 red + 4 blue = 22 balls  part (a)

18/22 = 9/11   part (b) simplify

9/11 * 100     part (c) multiply the fraction by a hundred to get the percentage

81.81 ~ 81%  part (d) solve

Answer:

81 9/11%

Step-by-step explanation:

First add the number of red and blue balls together. 18 + 4 = 22

What is the number of red balls? It’s 18

We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.

Therefore, the answer is 81 9/11%.

Answer:

x = 1,213

y = 1,314

z = 714

Step-by-step explanation:

$10 = x

$20 = y

$30 = z

10x + 20y + 30z = 59,830

____________

Solving for x:

Since there 101 more $20 tickets than $10 tickets we are making the equation of:

y = x + 101

First equation (substitute the equation above for y)

x + (x+ 101) + z = 3,241

Subtract 101 from 3,241

2x + z = 3,140

Second equation (substitute y with 'x + 101 ')

10x + 20(x + 101) + 30z = 59,830

10x + 20x + 2,020 + 30z = 59,830

Subtract 2,020 from 59,830

10x + 20x + 30z = 57,810

Add 10x and 20x

30x + 30z = 57,810

Cancel out the 30's and divide 57,810 by 30

x + z = 1,927

Now solve using the first 2 equations

2x - z =3,140 = x + z = 1,927

Subtract z

2x = 3,140 = x + 1,927

Divide x

x = 3,140 = 1,927

Subtract 1,927 from 3,140

x = 1,213

____________________

Solving for y:

y = x + 101

y + 1,213 + 101

y = 1,314

____________________

Solving for z:

1,213 + 1,314 + z = 3,241 (Overall tickets sold)

2,527 + z = 3,241

Subtract 2,527 from 3,241

z = 714

____________________

Check math:

10x + 20y + 30z = 59,830

10(1,213) + 20(1,314) + 30(714) = 59,830

Step-by-step explanation:

We have been given an equation t=\frac{1}{500}dt=

d , where d represents distance traveled in miles and t represents time in hours.

To find the time taken by the flight to travel 800 miles, we will substitute d=800d=800 in our given equation as:

t=\frac{1}{500}\times 800t=

t=1.6t=1.6

1 hour equals 60 minutes.

0.6 hours = 0.6*60 minutes = 36 minutes.

Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

p=2

Step-by-step explanation:

Step-by-step explanation:

Now we have to,

→ Find the required value of p.

The equation is,

→ 7p + 3 = 4p + 9

Then the value of p will be,

→ 7p + 3 = 4p + 9

→ 7p - 4p = 9 - 3

→ 3p = 6

→ p = 6 ÷ 3

→ [ p = 2 ]

Hence, the value of p is 2.

if 10 operators worked on 120 pages for 2 hours

P operators will work on the same pages for 30min

note: 2hrs= 120min

Answer:

[-7, 0]

Step-by-step explanation:

The range describes all values that y can take on. You may notica that the highest point of the graph has an y coordinate of 0 while the lowest has one of -7. Both values are included because they have filled in dots: this means the parenthesis are closed. So, the range would be: [-7, 0]. An alternate way to write this is [tex]-7\leq y \leq 0[/tex].

Answer:

x = (v-w)/k

Answer:

x = [tex]\frac{v-w}{k}[/tex]

Step-by-step explanation:

xk = v - w ( isolate x by dividing both sides by k )

krutika................2400/40=60...............................

so the answer is A

Step-by-step explanation:

Answer:

A) Caroline

Step-by-step explanation:

To find this, simply divide the amount of words they type by the amount of minutes they type:

To solve Caroline's do:

3500/50=70

Caroline types 70 words per minute.

To solve Natasha's do:

4550/70=65

Natasha types 65 words per minute.

To solve Krutika's do:

2400/40=60

Krutika types 60 words per minute.

Since Caroline has the highest wpm, we can safely say that Caroline types the fastest rate of words per minute.

Answer:

y =-2x+3

Step-by-step explanation:

The y intercept is 3  ( the y intercept is when x =0)and the slope is -2

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y =-2x+3

Answer:

(2, -2)

Step-by-step explanation:

Solve 7x - 2y = 18 for x:

Substitute 2/7y+ 18/7 for x in -4x + 3y = -14

Substitute -2 for y in x = 2/7y + 18/7

Given that x = 2 and y = -2, the point is: (2, -2)

Therefore, the solution is (2, -2).

The complete table for the expression 2y=x+1 is below:-

x                   y                ( x, y)

-2              ( -1 / 2)             [ -2, ( -1 / 2)]      

-1                0                    [-1 ,0]

0               ( 1 / 2 )            [0, ( 1 / 2 )]

1                1                      [1,1]

2              ( 3 / 2 )             [2, ( 3 / 2 )]  

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The values of the expression 2y=x+1 will be solved as below:-

2y=x+1

2y = -2 + 1

y = -1 / 2

2y=x+1

2y = -1 + 1

y = 0

2y=x+1

2y = 1 + 1

y = 2 / 2 = 1

2y=x+1

2y = 2 + 1

y = 3 / 2

Therefore, the values of the expression are calculated above.
