What Is F(x)? Someone Please Help

Answers

Answer 1

Given:

The table of values for the function f(x).

To find:

The equation for the function f(x).

Solution:

From the given table it is clear that the function passes through the point (0,5) and (1,8). So, the equation of the linear function that passes through the (0,5) and (1,8) is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-5=\dfrac{8-5}{1-0}(x-0)[/tex]

[tex]y-5=\dfrac{3}{1}x[/tex]

[tex]y=3x+5[/tex]

The function notation is:

[tex]f(x)=3x+5[/tex]

Therefore, the required function is [tex]f(x)=3x+5[/tex].

Answers

Answer:

The insurance costs to send goods valued at $16,400 is $410  

Step-by-step explanation:

The amount it costs an exporter to insure goods to send overseas = (5/2)% of the value of the goods

Therefore;

The insurance costs, 'C' to send goods valued at $16,400 is given as follows;

C = $16,400 × (5/2)/100 = $410

The insurance costs to send goods valued at $16,400 = $410

Robert takes out a loan for $7200 at a 4.3% rate for 2 years. What is the total paid amount at the end of the loan?

Answers

Answer:

$7819.20

Step-by-step explanation:

total paid amount at the end of the loan= loan taken + interest on the loan

loan taken = $7200

interest on the loan can be determined using this formula

Interest = principal x intrest rate x time

7200 x 0.043 x 2 = $619.20

total paid amount at the end of the loan= $7200 + $619.20 = $7819.20

Brad read that you should drink at least 2 quarts of water a day. Yesterday he drank 3 cups in the morning, 1 quart in the afternoon, and 1 pint in the evening. Did Brad drink at least 2 quarts of water? Explain.

Answers

Answer:

yes he drank 2.25 quarts

Step-by-step explanation:

convert the cups to quarts

1 cup = 0.25 quarts

3 cups x 0.25 = 0.75 quarts

convert the pints to quarts

1 pint = 0.5 quarts

add all the amount of water drank together

0.75 quarts + 1 quart + 0.5 quarts =  2.25 quarts

For the function, f(x) =1/4 x - 2, find x if f(x) = -1.

Answers

Answer:

x = 4

Step-by-step explanation:

Given function  

f(x) =1/4 x - 2

Find x if f(x) = -1

1/4x - 2 = - 11/4x = 2 - 11/4x = 1x = 1*4x = 4

Answer:

x=4

Step-by-step explanation:

f(x) =1/4 x - 2 when f(x) = -1.

-1=1/4x-2

-1+2=1/4 x

1×4=x

x=4

x = 5

Step-by-step explanation:

4x + 8 - 9x = -17

combine like terms:

-5x = -25

divide both sides of the equation by -5:

x = 5

Answer:

x=5

Step-by-step explanation:

4x-9x+8=-17

-5x+8=-17

subtract 8 from both sides and you get:

-5x=25

divide 5 from both sides, and you get x=5! :)
