Answer:

# yellow = 20

# blue = 23

# red = 5

Step-by-step explanation:

let 'r' = # red marbles

let '4r' = # yellow marbles

let '3+4r' = # blue marbles

r + 4r + 3 + 4r = 48

9r + 3 = 48

9r = 45

r = 5

red = 5

yellow = 4(5) = 20

blue = 3+4(5) = 23

See the explanations below

Step-by-step explanation:

Given the function y = x²+12x

We are to find the inverse and identify the error in the calculation:

Step 1: Replace y with x

x = y²+12y

First Error: There is an error here y, the variable attached to x should be y and not x that is y =  y²+12y and not y = y²+12x. The x should be totally replaced with

The second error is where he wrote y = √-11x

The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)

Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been x <0 and not

x< 0

Step-by-step explanation:

Lannister checks out 6 sets of book

Each set had the same number of books

She reads 7 books and has 11 more to go

Therefore the number of books in each set can be calculated as follows

= 11+7

= 18

18/6

= 3

Hence there are 3 books in each set

Answer:

n = 18

Step-by-step explanation:

(2n) and (n + 18) are vertically opposite angles and are congruent, then

2n = n + 18 ( subtract n from both sides )

n = 18

Answer:

Total: $21.76

Step-by-step explanation:

Abby: 8.25

Maya: 10.50

Kayla: 6.85

Since Abby has a coupon for 15% we would multiply each meal by 15% to see how much money will be taken off by the coupon.

Abby: 8.25 x 0.15= 1.24

Maya: 10.50 x 0.15=1.58

Kayla: 6.85 x 0.15=1.02

Next subtract the amount of money taken off by the coupon by each meal.

Abby: 7.01

Maya: 8.92

Kayla: 5.83

Total: $21.76

Answer:

Slope = 4 and y-intercept = 1

Step-by-step explanation:

→ To find the slope, look at the value before the x

4

→ To find the y-intercept, make x = 0 then the answer is the y-intercept

1

Answer:

X=-1/4 or y=1

Step-by-step explanation:

0=4x+1

-4x=1x=-1/4

y=4×0+1

y=1

Answer:

y -3 = 2( x-1)

Step-by-step explanation:

Point slope form of a line is

y-y1 = m(x-x1)  where m is the slope and ( x1,y1) is a point on the line

y -3 = 2( x-1)

4^3

you can write it like 4 × 4 × 4

you can also call it "Four to the Third power". or "Four cubed".

Answer:

x=1 and x=3

Step-by-step explanation:

When you factor it you get (x-1) and (x-3) then you subtract the 1 and 3 to the other side which is why the answer is positive.  

Answer:

x = 1, x = 3

Step-by-step explanation:

Equate the expression to zero, that is

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

Answer:

It's A

Step-by-step explanation:

For -1:

y = x + 6

y = 5

( -1, 5)

For 0:

y = x + 6

y = 6

(0, 6)

For 2:

y = x + 6

y = 8

(2,8)

For 4:

y = x + 6

y = 10

Answer:

p=90

Step-by-step explanation:

Divide 2/3 on both sides. When you divide a fraction, you actually

multiply by its reciprocal, or opposite (3/2).

2/3p=60

*3/2 *3/2

p=180/2

p=90

Hope this helps and have a great day C:

Answer:

p = 1/90

Step-by-step explanation:

determine the defined range

2/3p = 60, p = 0

then multiply both sides of the equation by 3p

2 = 180p

swap both sides of the equation

180p = 2

then Divide both sides of the equation by 180

p = 1/90 p = 0

check the solution is it in the defined range

then you should get your answers

Answer:

✔ 6

✔ 3

✔ 64

✔ 64

Step-by-step explanation:

We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3. We can use trigonometric functions to find the answer.

Trigonometric functions are the ratios existing between the sides of a right-angled triangle. These ratios are constant for every right-angled triangle.

The sine of any angle is given by opposite side/hypotenuse.

The cosine of any angle is given by the adjacent side/hypotenuse.

We can find the value of a using sin 45:

sin 45 = 1/√2

⇒ a/17√2 = 1/√2

⇒ a/17 = 1

⇒ a = 17

We can find the value of c using cos 45:

cos 45 = 1/√2

⇒ c/17√2 = 1/√2

⇒ c/17 = 1

⇒ c = 17

We can find the value of b using sin 30:

sin 30 = 1/2

⇒ a/b = 1/2

Substitute the value of a:

17/b = 1/2

⇒ b = 34

Now we can use cos 30 to find the value of d:

cos 30 = √3/2

⇒ d/b = √3/2

Substitute the value of b:

d/34 = √3/2

⇒ d = 34*√3/2

⇒ d = 17√3

Therefore, We have found the value of each variable as a = 17, b = 34, c = 17 and d = 17√3.

Answer:

$165

Step-by-step explanation:

Cost of dinner = $132

Sales tax = 10% of dinner cost

Tip left = 15% of dinner cost

Amount of sales tax :

10% of $132

0.1 * $132 = $13.2

Amount of tip left :

15% * $132

0.15 * $132 = $19.8

Total cost of dinner :

Dinner cost + sales tax + tip

$132 + $13.2 + $19.8

= $165
