40 pts help Each month, Jason wants to save money for a mini IPAD. The mini IPAD cost $800. Jason has $120 and can save $40 a month. The function f(x) = 40x + 120 can be used to represent the number of months and f(x) represents amount of money saved.
Part 1: f(9) = 480 - What does this represent in context?


Part 2: How much money will Jason have saved after 3 months? Use function notation to show your thinking.


Part 3: How much more will he still need to save in order to buy the iPAD mini?

Step-by-step explanation:

Answer:

The number of fishes person b initially has is 0

The number of fishes person a initially has is x, where x is any natural number

Step-by-step explanation:

The given parameters are;

let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;

x - x/2 = y + x/2

2·x - x = 2·y + x

2·x = 2·y + 2·x

∴ y = 0

Therefore;

The number of fishes person b initially has = 0

The number of fishes person a initially has = x, where x is any natural number.

Answer:

y=1/2x+5

Step-by-step explanation:

first you have to find the slope by using [tex]\frac{y2-y1}{x2-x1}[/tex]

so when you plot in your points and you will get 1/2x.

then you need to find your y-intercept

and since you don't have a 0 you have to slove by using y=mx+b (slope-intercept) formula

you plug in your points and you will get

b=5 and that is how you get your equation.

Answer:

Lesser x = -7

Greater x = 7

Step-by-step explanation:

g(x)= -10x² + 490

don't ask me Khan academy says so

Answer:

lesser x=-7 greater x=7

Step-by-step explanation:

use algebra to find x^2 by itself

x^2 =49

now take the square root of booth sides, both positive and negative

and you have your answer

Answer:

Option C. [tex]98^{\circ}[/tex]

Step-by-step explanation:

[tex]\angle DAB + \angle BAC = 180[/tex] (the two angles sum to the angle of a straight line: [tex]180^{\circ}[/tex])

[tex]122+\angle BAC = 180[/tex]

[tex]\angle BAC = 180-122[/tex]

[tex]=58^{\circ}[/tex]

[tex]24+58+x = 180[/tex] (sum of interior angles of triangle is [tex]180^{\circ}[/tex])

[tex]82+x=180[/tex]

[tex]x=98^{\circ}[/tex]

∴ Option C is correct.

Hope this helps :)

Answer: you didnt post graphs to look at

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

we know that

[tex]\angle 1 =\angle 2[/tex]

and that

[tex]\angle 1 +\angle 2 = 180[/tex]

so we substitute angle 2 by angle 1

[tex]\angle 1 +\angle 1 = 180\\\\2\angle 1=180\\\\\angle 1 = 90[/tex]

so there we have it

[tex]\angle 1 = 90 =\angle 2[/tex]

Answer:

7+4x=13+x

4x-x=13-7

3x=6

3 3

x =2

Step-by-step explanation:

because when 7 crosses the equal to sign it becomes negative and when the x from the other side crosses the equal sign it also will become negative which will become 4x-x=13-7

which is 3x=6 so u divide both sides by the coefficient of x which is three which will give u 2

Step-by-step explanation:

3/6=k/7

cross multiply then

6k=21

divide by the coefficient of k

k=3.5

Answer:

-4

Step-by-step explanation:

arranging in ascending order

-20,-20,-17,-14,-4,2,7,7,13

number of terms=9

middle term= (n+1)/2=(9+1)/2=5th=-4

Answer:

-4

Step-by-step explanation:

To identify the media, you have to:

''Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.''

If we follow the steps, the answer should be -4. With 9 data values, the middle number is the data value at position 5. And position 5 is -4. So the answer will be -4. Hope this helps !
