Answer 2

A function assigns the value of each element of one set to the other specific element of another set. The value of f(8) is 5.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given is mentioned below. Now, the value of the function can be found as shown below.

A.) f(-10)=?

When the value x is -10, it will lie in the first category of the function, therefore, the function for this value of x will be,

[tex]f(x) = 2x+1\\\\f(-10) = 2(-10)+1\\\\f(-10) = -20+1 = -19[/tex]

B.) f(2) = ?

When the value x is 2, it will lie in the second category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x^2\\\\f(2) = 2^2 = 4[/tex]

C.) f(-5)=?

When the value x is -5, it will lie in the first category of the function, therefore, the function for this value of x will be,

[tex]f(x) = 2x+1\\\\f(-5) = 2(-5)+1\\\\f(-5) = -10+1 = -9[/tex]

D.) f(-1)=?

When the value x is -1, it will lie in the second category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x^2\\\\f(-1) = (-1)^2 = 1[/tex]

E.) f(8)=?

When the value x is 8, it will lie in the third category of the function, therefore, the function for this value of x will be,

[tex]f(x) = x-3\\\\f(8) = 8-3 = 5[/tex]

can someone help me to solve 3/4÷1/2=​

Answers

Answer:

3/4 ÷ 1/2 is one and one half or 3/2

Answer:

1.5 or 1 1/2

Step-by-step explanation:

3/4 divided by 1/2 is simply a reverse order of multiplication.

As you see if you swap the 1 and 2 in one half you get 2 over 1.

This changes the division sign to a multiplication sign.

Thus then you can multiply 3/4 by 2 to get 6/4.

6/4 then can be simplified as 1 and 1/2 or 1.5.

4(h + 12) = 80

Answers

Answer:

h=8

Step-by-step explanation: can u make me brainliest plz?

Step 1: Simplify both sides of the equation.

4(h+12)=80

(4)(h)+(4)(12)=80(Distribute)

4h+48=80

Step 2: Subtract 48 from both sides.

4h+48−48=80−48

4h=32

Step 3: Divide both sides by 4.

4h/4=32/4

h=8

so first you want to distribute. multiply 4 by h and 4 by 12
4(h+12)=80
4h+48=80
now isolate the variable. to do that you have to subtract 48 and get it on the other side. but remember, whatever you do to one side you have to do to the other
4h+48=80
-48 -48
4h=32
now you have to do inverse operations and divide 4h by 4. remember, whatever you do to one side you have to do to the other.
4h=32
— —
h=8

there you go! hope that helps!

Adrienne said that a vertical stretch by a factor of 4, a horizontal shift to the left 1 unit, and a vertical shift down 3 units of the graph of the parent function f(x)=ex produce the graph of the function g(x)=4ex−1+3. Explain whether Adrienne is correct and, if not, determine the transformations that produce the graph of the function g(x)=4ex−1+3 from f(x)=ex.

Answers

Answer:

known facts:

The graph of y=f(x−a), a>0

y=fx-a, a>0  

can be obtained by shifting graph y=f(x)

y=fx, a units right side of x-axis. The graph of y=f(x)+a, a>0 y= fx+ a,a>0

can be obtained by shifting graph y=f(x)

y=fx, a units upwards along y-axis.

Adrienne said:

a vertical stretch by a factor of 4, a horizontal shift to the left 1 unit and a vertical shift down 3 units of the graph of the parent function f(x)=ex

f(x)=e^x

produce the graph of the function g(x)=4ex−1+3

g(x)=4e^x-1+3.

by the above known facts, it can be concluded that

Adrienne is not correct

Step-by-step explanation:

i hope this helps you, i'm still doing it but i have to go for a min, one sec! <3

the correct transformations for the function g(x) = 4eˣ - 1 + 3 from the parent function f(x) = eˣ are:

- Vertical Stretch by a factor of 4.

- Horizontal Shift to the Right 1 unit.

- Vertical Shift Down 3 units.

Adrienne's statement about the transformations applied to the parent function f(x) = eˣ is not entirely correct. Let's analyze the given function g(x) = 4eˣ - 1 + 3 and determine the correct transformations.

1. Vertical Stretch by a factor of 4: This transformation is correct. Multiplying the function by 4 causes a vertical stretch, which magnifies the y-values by a factor of 4.

2. Horizontal Shift to the Left 1 unit: Adrienne incorrectly mentioned a horizontal shift to the left. In the given function, g(x), there is no explicit horizontal shift. The -1 in g(x) = 4eˣ - 1 + 3 is actually a reflection of the graph across the y-axis, causing a horizontal shift to the right by 1 unit. So, there is a horizontal shift to the right by 1 unit, not to the left.

3. Vertical Shift Down 3 units: This transformation is correct. Adding 3 to the function shifts the graph vertically downward by 3 units.

Therefore, the correct transformations for the function g(x) = 4eˣ - 1 + 3 from the parent function f(x) = eˣ are:

- Vertical Stretch by a factor of 4.

- Horizontal Shift to the Right 1 unit.

- Vertical Shift Down 3 units.

Lionel walks 3/5 mile in 1/3 of a day. Cristiano walks 5/8 mile in 2/6 of a day.
Who walked farther, Cristiano or Lionel? How much did each boy walk in 1 day?

Answers

Answer:

            Cristiano walked farther In 1 day:   Lionel walked  1.8 mile                  Cristiano walked 1.875 mile

Step-by-step explanation:

2/6 = 1/3  so we just need to know what is more 3/5 or 5/8

3/5 = (3•8)/(5•8) = 24/40

5/8 = (5•5)/(8•5) = 25/40

25 > 24  so 5/8 > 3/5

so Cristiano walked farther

They walk for 1/3 of a day so in a whole day they walk three times the distance

3/5 • 3 = 9/5 = 1 4/5 = 1.8 mile

5/8 • 3 = 15/8 = 1 7/8 = 1.875 mile

Calculate the following using the Density Formula: What is the volume of the Ms. Gonsalez's phone that he dropped in his sink, if the mass of the phone is 12.4 g and the density is 6.2 g/mL? *

Answers

Answer:

2 mL³

Step-by-step explanation:

Use the density formula, D = m/v, where m is the mass and v is volume.

Plug in the mass and density, then solve for the volume:

D = m/v

6.2 = 12.4/v

6.2v = 12.4

v = 2

So, the volume is 2 mL³

To save money for prom this weekend, Tom is going to walk his neighbor's dog for $6 per hour and wash cars for $7.50 per hour. His mother said he can work no more than 15 hours to ensure he keeps up with his homework. Tom needs to make at least $75 to cover prom expenses. If d represents the number of hours walking his neighbor's dog and c represents the number of hours washing cars, which system of inequalities represents this solution?

Answers

Answer:

Hey there! The answer you selected is correct!

Step-by-step explanation:

$6 x the number of hours he works + $7.50 times the number of hours he works has to be less than or equal to (≤) 15 hours. The number of hours he works has to be more than or equal (≥) to $75. Great job choosing the correct answer!

The system of inequalities represents this solution is B. 6c + 7.5d ≥ 75 ;

d + c ≤ 15.

What is inequality?

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now it is given that,

Money from walking neighbor's dog = $6 per hour

Money from car wash = $7.5 per hour

Total Number of hours of work not more than 15 hours

Now, if d represents the number of hours walking his neighbor's dog and c represents the number of hours washing cars

So, money from walking neighbor's dog = 6c

and money from car wash = 7.5d

Therefore total money saved = 6c + 7.5d

∵ Total Number of hours of work is not more than 15 hours

⇒ d + c ≤ 15

∵ Tom needs to make at least $75 to cover prom expenses

⇒ 6c + 7.5d ≥ 75

The system of inequalities represents this solution is B. 6c + 7.5d ≥ 75 ;

d + c ≤ 15.
