Answer:

the book store selling 7 books for $39.55 (the book store)

Step-by-step explanation:

we have to calculate what each book costs. to find out what each book costs, we have to use division...

so for the book store:

39.55 / 7 = 5.65       -       this means that each book costs $5.65 by itself

for the online store:

24.96 / 3 = 8.32       -       this means that each book costs $8.32 by itself

now we have to compare the prices... $5.65 costs less than $8.32, so the book store would have a lower unit price.

Answer:

1/8

Step-by-step explanation:

Probability denotes the possibility of something happening. It is a field of mathematics that studies the probability of a random event occurring. From 0 to 1.

the value is expressed.

When a coin is tossed, the chance of it landing on heads is 1/2, and vice versa.

So, we divide 1/2 by the number of times it lands on heads to get 1/4. However, when the second one landed on tails, we must multiply it by 1/2 again, making 1/4 x 1/2 = 1/8.

An associate in a scatter plot tells us the relation between the two variables. The points that are true about the given scatter plot are F and C.

An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:

Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.

Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.

Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line.

Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.

The points that are true about the given scatter plot are:

F.) A cluster appears to be at the bottom left corner.

C.) There appears to be a positive association.

The equation that can pair with x + 2y = 5 to generate an inconsistent system is given by:

2x + 4y = 3.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

A inconsistent system is a system that has no solution, that is, when the coefficients of x and y are multiplies, but the result is not. Hence, the option that gives an inconsistent system is given by:

2x + 4y = 3.

As when we try to solve the system, we would end up with the following situation:

The range tells us the possible y-values that occur in the function.

When describing the range, we can write an inequality using y.

When describing the range of a quadratic function, we typically use the ≥ or ≤ symbols when writing the inequality.

To write the range of a quadratic function,

We're given:

Because we're directly given the vertex, we just have to determine now whether the parabola opens up or down.

The other points that fall on the graph that we're given all have a lower y-coordinate value than 4, that means this parabola opens down.

Therefore, all other y-values for the function will be less than 4.

Therefore, y ≤ 4.

y ≤ 4

The polynomial with 6 roots is the one of degree 6, so the correct option is:

[tex]f(x) = 7x^6 + 3x^2 + 12[/tex]

You need to remember that if p(x) is a polynomial of degree N, then it has N roots (such that some of these N roots may be equal or not).

Then we just need to find the polynomial of degree 6. (Remember that the degree represents the maximum exponent of the polynomial).

In this case, the only one of degree 6 is:

[tex]f(x) = 7x^6 + 3x^2 + 12[/tex]

Answer:

Step-by-step explanation:

1. Group all a terms on the left side of the equation

Add a to both sides

[tex]46a+\frac{5}{3}+a=\frac{24}{5}-a+a[/tex]

Group like terms:

[tex]46a+a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]

Simplify the arithmetic:

[tex]47a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]

Group like terms:

[tex]47a+\frac{5}{3}=-a+a+\frac{24}{5}[/tex]

Simplify the arithmetic:

[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]

2. Group all constants on the right side of the equation

[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]

Subtract [tex]\frac{5}{3}[/tex] from both sides:

[tex]47a+\frac{5}{3}-\frac{5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Combine the fractions:

[tex]47a+\frac{5-5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Combine the numerators:

[tex]47a+\frac{0}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Reduce the zero numerator:

[tex]47a+0=\frac{24}{5}-\frac{5}{3}[/tex]

Simplify the arithmetic:

[tex]47a=\frac{24}{5}-\frac{5}{3}[/tex]

Find the lowest common denominator:

[tex]47a=\frac{24\cdot 3}{5\cdot 3}+\frac{-5\cdot 5}{3\cdot 5}[/tex]

Multiply the denominators:

[tex]47a=\frac{24\cdot 3}{15}+\frac{-5\cdot 5}{15}[/tex]

Multiply the numerators:

[tex]47a=\frac{72}{15}+\frac{-25}{15}[/tex]

Combine the fractions:

[tex]47a=\frac{72-25}{15}[/tex]

Combine the numerators:

[tex]47a=\frac{47}{15}[/tex]

3. Isolate the a

[tex]47a=\frac{47}{15}[/tex]

Divide both sides by 47:

[tex]\frac{47a}{47}=\frac{\frac{47}{15}}{47}[/tex]

Simplify the division:

[tex]a=\frac{47}{15\cdot 47}[/tex]

Simplify the right side:

Answer:

(f ∘ f)(–1) = –1

Step-by-step explanation:

To solve a composite function, rewrite using brackets and solve from inside to outside.

(f ∘ f)(x) is the same as:    f[f(x)]

Given that x = –1 in (f ∘ f)(–1), we are solving for:

f[f(–1)] = ?

Solve for f(–1) inside the square brackets first.

f(x) = x³

f(–1) = (–1)³    Simplify.

f(–1) = –1       Solved the inside.

Substitute f(–1) = –1 into the square brackets.

f[f(–1)] = f[–1]

Now, we can solve the outside.

Solve with the equation of the function, x³.

f[–1] = x³

f[–1] = [–1]³     Substitute x = –1.

f[–1] = (–1)³     Simplify.

f[–1] = –1        Final answer

11/12 of the garden is occupied by broccoli and peppers. Therefore, 11 /12 of the garden has vegetable growing in it.

We know that 1/4 of the garden has broccoli and 2/3 of the garden has peppers, Therefore, let's add up those two fractions to find out how much of the whole garden that has broccoli and peppers.

Therefore,

1/ 4 + 2 / 3 = ?

The denominator needs to be the same. Therefore,

1/4 × 3/ 3 = 3 / 12

2/3 × 4 /4 = 8 / 12

Hence,

3 / 12 + 8 / 12 = 11 / 12

11/12 of the garden is occupied by broccoli and peppers. Therefore, 11 /12 of the garden has vegetable growing in it.

Answer:

c = 2

m= 1

Step-by-step explanation:

Im guessing you will need to use simultaneous equations

Let 'c' be the cost of 1 cookie and 'm' be the cost of 1 muffin

1) 2c + 1m = 5 -

2) 1c + 1m = 3

c / = 2

So c is 2

1) Label the equations 1 and 2

2) Find a common term in both equations ( bold)

3) Eliminate 1m by subtracting equation (2) from equation 1

( To know if to subtract or add always follow this rule: If the common terms and the same sign subtract if they are a different sign add)

4) Substitute c in any of the equation ( 1 or 2) to find m

I will use equation 2 because I think its easier

2) 1c+1m = 3

2 + m = 3

m= 3-2

m= 1
