Cindy had 13 stickers. She bought 18 stickers from a store in the mall and got 5 stickers for her birthday. Then Cindy gave 8 of the stickers to her sister and used 10 to decorate a greeting card. How many stickers does Cindy have left?

Answers

Answer:

18 stickers.

Step-by-step explanation:

Cindy buys 18 more stickers in the start. This results in 13+18= 31 stickers. She then gets five for her birthday. 31+5=36 so she now has 36 stickers but she then gives eight away which means she has 36-8=28 stickers. She uses ten stickers to decorate so Cindy has 28-10=18 stickers left

A polynomial function has a zeros at -1,2,7 and all are multiplicity of 1 write a function in standard form that could represent this function

Answers

Final answer:

To create a polynomial with zeros at -1, 2, and 7, each with a multiplicity of 1, you start with the factored form (x + 1)(x - 2)(x - 7) and expand it to get the standard form x^3 - 8x^2 + 15x + 14.

Explanation:

The question involves finding a polynomial function with given zeros. When a polynomial has zeros of -1, 2, and 7, all with a multiplicity of 1, the function can be expressed as product of linear factors associated with each zero. Starting from the factored form f(x) = (x - (-1))(x - 2)(x - 7), which encapsulates the given zeros, you can then expand this expression to get the polynomial in its standard form.

The expanded form of the polynomial is then f(x) = (x + 1)(x - 2)(x - 7), which, when expanded, yields f(x) = x^3 - 8x^2 + 15x + 14. This is a polynomial function in standard form that has the required zeros, each with a multiplicity of 1.

Answers

Simplifying

4x + -3y = 12

Solving

4x + -3y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

4x + -3y + 3y = 12 + 3y

Combine like terms: -3y + 3y = 0

4x + 0 = 12 + 3y

4x = 12 + 3y

Divide each side by '4'.

A number cube is rolled 300 times. Predict how many times a number greater that 3 would be rolled

Answers

Answer:

150

Step-by-step explanation:

4, 5 and 6 are all numbers greater than 3.

The chances of rolling a 4 is 1/6, that of a 5 is 1/6, and that of a 6 is 1/6.

The chances of rolling a number greater than 3 is thus 3/6, or 1/2.

This is theoretical probability; you haven't actually observed this happening.

We can now multiply (300 rolls) by this probability 1/2, obtaining 150.

We predict that in 300 rolls, 150 numbers greater than 3 would be rolled.

If b2 + 2b − 24 = 0, and b < 0, what is the value of b?


A) −6

B) −4

C) −2

D) 0

Answers

Final answer:

The value of b is -6.

Explanation:

To find the value of b, we need to solve the quadratic equation b2 + 2b - 24 = 0.

Since b < 0, we can eliminate the positive solution.

We can factor the equation by finding two numbers whose product is -24 and sum is 2.

The numbers are -4 and 6.

So, the factored form of the equation is (b - 4)(b + 6) = 0.

Setting each factor equal to zero, we find that b = -6 or b = 4.

Since b < 0, the value of b is -6.

https://brainly.com/question/30098550

#SPJ12

Final answer:

Using the quadratic formula, we find that b = -6 (option A), considering the requirement that b < 0 for the equation b² + 2b - 24 = 0.

Explanation:

To find the value of b given the quadratic equation b² + 2b − 24 = 0 and knowing that b is less than zero, we can use the quadratic formula:

The quadratic formula is −b ± √(b² − 4ac /2a), where a, b, and c are coefficients from the quadratic equation in the form ax2 + bx + c = 0.

In this case, a = 1, b = 2, and c = −24. Applying these values to the quadratic formula, we have:

−(2) ± √((2)² − 4(1)(−24) /2(1))

The discriminant part of the formula, b² − 4ac, equals (2)² − 4(1)(−24) = 4 + 96 = 100. Therefore, the square root of the discriminant is 10.

Simplifying further, we have:

(−2 ± 10) / 2 = −6 or +8

Since b < 0, we disregard the positive solution and consider b = −6, which is option A.

Answers

Answer:

$3.79 for an 8 foot board

Step-by-step explanation:

The way to find the answer is calculating the price per foot.

Part 1

$3.79 for an 8 foot board.

Answers

a)

Subtract 0.4 from both side.

-9x +0.4 = 4

-9x + 0.4 - 0.4 = 4 - 0.4

-9x = 3.6

The steps needed to solve the given equation is required.

Adding the opposite value of the constant to both sides.

Divide both sides by the coefficient of the variable.

The solution to the equation is [tex]x=-0.4[/tex]
