The graph of a function f is shown below.
Find f (2)

Answers

Answer:  f(2) is 3.

Step-by-step explanation:

f(2) just means "what is the vale of the function, f, when x = 2?  Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3.  So f(2) = 3.

======

[One could also determine the equation for the line.  Provided below.]  

The slope is -(1/2) and the y-intercept is 4:

y = -(1/2)x + 4

For x=2,

y = -(1/2)*(2) + 4

y = 3  

y(2) = 3

Divide the cost of the noodles by the ounces and you'll get your answers and then you have to pick the one with the least cost per noodles.

The 6 ounce costs .32 each

The 14 ounce costs .33 each

And the 20 ounce costs .31 each

can anyone help me out with this?

Answers

Given :

Evaluate the equation.

2x – 4(x – 2y) + 6y = ?

When x = 5 and y = 2 then,

2x – 4(x – 2y) + 6y

= 2(5) – 4[(5) – 2(2)] + 6(2)

= 10 – 4(5 – 4) + 12

= 10 – 4*1 + 12

= 10 – 4 + 12

= 22 – 4

= 18

hope this helps ^^

A friend is having trouble comparing rational numbers. Write an explanation that will tell your friend how to decide if a rational number is greater than, less than, or equal to another rational number.

Answers

If one is positive and the other is negative, the positive number is greater than the negative number. If both are positive (or negative), change both the numbers into fractions with common (positive) denominator. Next, compare the numerators. The fraction having the greater numerator is larger.

Find f(-2)

Answers

Answer:

[tex]f(-2)=-17[/tex]

Step-by-step explanation:

[tex]f(-2)=2(-2)^2-25\\\\f(-2)=2(4)-25\\\\f(-2)=8-25\\\\f(-2)=-17[/tex]

f(x) = 2x² - 15

f(-2) = ?

Substitute -2 in the place of x.

f(x) = 2x² - 15

f(-2) = 2(-2)² - 15

f(-2) = 8 - 15

f(-2) = -7

17 rounded to the nearest 10th of a degree

Answers

Answer: 20

Step-by-step explanation:

17 is closest to 20 :)

(sorry if this is wrong)

20 because if your rounding to the nearest 10 the range you have is 10-20 because 17 is in between 10 and 20, then you can count or just tell which one 17 is closer to: 17-10=7 so 17 is 7 away from ten, then 20-17=3 so 17 is three away from 20. so now you choose the answer that is closer to the number:)

7. Write an inequality that matches the graph shown.

Answers

Step-by-step explanation:

first, we define the line.

the slope is -3 (as for every increase of x by 1 unit, y changes by -3 units, which makes the slope -3/1 = -3).

the y-intercept is 2.

so, the line is

y = -3x + 2

now the graph shows that we need to define all y values that are below (and that means smaller than) the result values of the line function.

the line is not included.

therefore the inequality is

y < -3x + 2 or 3x + y < 2

Explain your answer using words, and show your work using division of fractions.

Answers

Answer:=> 10 months

Given :

Step-by-step explanation:

Given :

1 / 4 inches = 1 month

Find :

5 / 8 inches = ? months

According to the question :

1 month = 1 / 4 inches

5 / 8 inches = ' x ' months

=> ( 5 / 8 ) / ( 1 / 4 ) = x

=> ( 5 / 8 ) × ( 4 / 1 ) = x

=> ( 5 × 2 ) / 1 = x

=> 10 / 1 = x

=> x = 10.

So, it takes 10 months.

Answers

Answer:

4.25+9.75+0.5x≤18

Step-by-step explanation:

4.25+9.75+0.5x≤18

14+0.5x≤18

0.5x≤4

x≤8

She can buy at most 8 packs of crackers.

Hope this helps :)

Fiona can buy maximum 8 number of packages of crackers.

What is subtraction?

Subtraction is mathematic operation. Which is used to remove terms or objects in expression.

Given that Fiona has $18 to spend and she spent $4.25 .

Now, she has the money $18 - $4.25 = $ 13.75

And she needs to save $9.75 from rest of the amount.

Therefore, $13.75 - $ 9.75 = $4

Now she has $4 to spend and one packet of crackers cost $0.50.

So $4 / $0.50 = 8 number of packages Fiona can buy with the rest of money.

Therefore, Fiona can buy maximum 8 number of packages of crackers.
