Answer:

Assuming you meant 25% of her money, the answer should be D - $29

Step-by-step explanation:

$29 * .25 = $7.25

$29 - $7.25 = $21.75

WILL GIVE BRAINLIEST!!!!!!! A boy had 20 cents. He bought x pencils for 3 cents each. If y equals the number of pennies left, wr

kumpel [21]

Answer:

Hey there!!

The total number of cents - 20

Cost for each pencil - 3 cents

Number of pencils bought - ' x '

y = number of pennies left

What is the domain ?

Show how y is dependent on x ..

Let's get this into an equation :

... The total cost for x pencils bought = 3x

... Number of pennies left = 20 - 3x

... y = number of pennies left

... y = 20 - 3x

Notice : If the x value changes, the y value changes too

... If x = 1 , then , y = 17; If x = 2 , then , y = 14

Hence, we could say y is dependent upon x

Domain = ?

... Remember - The total number of pennies = 20 ; hence, the total cost cannot go above 20 cents.

Hence, we will have to work with inequalities

The equation :

... 20 ≥ 3x

Divide 3 on both sides

20 / 3 ≥ x

x ≥ 6.667

Let's take this as 6

Hence , the domain will be :

D : { 1 , 2 , 3 , 4 , 5 , 6 }

Hope my answer helps!

Answer:

The distance between E and F is 5 units

Step-by-step explanation:

E and F are share the same y-coordinates. So for this part it is okay to not use the distance formula. 

So you will be having:

E (5,8) and F (5,3)

EF = 8-3=5

OR 

YOU CAN USE THE DISTANCE FORMULA AS INDICAYED IN THE PICTURE.

Hopefully the picture is clear and understandable and younger the explanation.

The graphs below have the same shape. What is the equation of the red graph?

Sveta_85 [38]

we have

$g(x)=4-x^{2}$

the vertex of the function g(x) is the point $(0,4)$

the vertex of the function f(x) is the point $(0,0)$

the rule of the translation of g(x) to f(x) is

(x,y)------> (x,y-4)

that means

the translation is $4$ units down

therefore

the equation of the function f(x) is

$f(x)=g(x)-4\\f(x)=(4- x^{2})-4 \\f(x)=- x^{2}$

therefore

the answer is

$f(x)=- x^{2}$
