Answer:

Step-by-step explanation:

You want to know the prices of jelly beans and almonds when you can buy 7 pounds of jelly beans and 9 pounds of almonds for $46, or 5 pounds of jelly beans and 3 pounds of almonds for $20.

The equations describing each purchase can be written as ...

A graphing calculator plots these equations easily, and shows you the solution is (j, a) = (1.75, 3.75).

Jelly beans are $1.75 per pound; almonds are $3.75 per pound.

If you like, you can solve these equations by elimination. We notice the coefficients of 'a' have a simple ratio, so we can eliminate 'a' easily.

  3(5j +3a) -(7j +9a) = 3(20) -(46) . . . . . subtract the first from 3 times the second

  8j = 14 . . . . . simplify

  j = 1.75 . . . . . divide by 8

Substituting into the second equation, we get ...

  5(1.75) +3a = 20

  3a = 11.25 . . . . . . . . . subtract 8.75

  a = 3.75 . . . . . . . . divide by 3

Jelly beans are $1.75 per pound; almonds are $3.75 per pound.

Answer:

-1, -10, -26

Step-by-step explanation:

f(x) = -x² - 1

g(x) = x + 5

f(g(x)) =

-(g(x))² - 1 =  ==> plugin g(x) for x in f(x) in order to get f(g(x))

-(x + 5)² - 1 =  ==> plugin x+5 for g(x)

-(x + 5)(x + 5) - 1 =

-(x(x + 5) + 5(x + 5)) - 1 =   ==> distribute (x+5) to x and 5

-((x*x + 5*x) + (5*x + 5*5)) - 1 = ==> simplify

-(x^2 + 5x + 5x + 25) - 1 =

-(x^2 + 10x + 25) - 1 =

-x^2 - 10x - 25 - 1 = ==> distribute the negative sign to x^2, 10x, and 25

-x^2 - 10x - 26 = -1x^2 + (-10x) + (-26)

Subtracting by a positive number is equivalent to adding by a negative number

Answer: -1, -10, -26

Answer:

b = √(m+g²)/4f

Step-by-step explanation:

Step-by-step explanation:

To convert 186283 miles per second to feet per hour, we need to first convert the distance from miles to feet. There are 5280 feet in a mile, so 186283 miles is equal to 186283 * 5280 = 9,839,784,000 feet.

We also need to convert the time from seconds to hours. There are 3600 seconds in an hour, so 186283 seconds is equal to 186283 / 3600 = 51.8 hours.

Therefore, 186283 miles per second is equal to 9,839,784,000 feet per 51.8 hours, or approximately 188,822,900 feet per hour. This is the final answer.

Answer:

I don't know this is confused

Answer: $13.50

Step-by-step explanation:

It will cost Miguel $13.50 to send 6 small packages and 1 large package. To find the total cost, we can first calculate the cost of sending the small packages by multiplying the cost per small package by the number of small packages: 2.20 * 6 = $<<2.20*6=13.20>>13.20

We can then add the cost of the large package to find the total cost: 13.20 + 3.90 = $<<13.20+3.90=17.10>>17.10.

Therefore, it will cost Miguel $17.10 to send 6 small packages and 1 large package.

The region where the three circles overlap represents the intersection of all three sets. The region inside U but outside Y and Z represents the elements in U that are not in Y or Z. The region inside Y but outside U and Z represents the elements in Y that are not in U or Z. The region inside Z but outside U and Y represents the elements in Z that are not in U or Y. Finally, the region outside all three circles represents the elements that are not in any of the sets U, Y, or Z.

Answer:

Cubic, Binomial

Step-by-step explanation:

A cubic function is when the degree of the polynomial is 3

The degree is the highest power

A binomial has 2 terms

So 8x^3-1 is a binomial and is cubic

After solving the equations, the value obtained for x and y will be equal to  (-1, 1).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

y = 2x + 3     (i)

y = -x            (ii)

Substitute equation (ii) in (i)

-x = 2x + 3

-x - 2x = 3

-3x = 3

x = -3/3

x = -1

Substitute x = -1 in equation (i)

y = 2x + 3

y = 2(-1) + 3

y = -2 + 3

y = 1

The value of y in the linear equation 7x - 6y = 17 is y = -(17 + 7x)/6

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable.

In this problem, we are to solve for y.

7x - 6y = 17

Step 1

Take 7x to the right hand side of the equation

-6y = 17 - 7x

Step 2

Divide both sides by the coefficient of y

-6y / -6 = (17 - 7x) / - 6

y = - (17 + 7x) / 6

The volume expression for the box is 1.728lwh and it means that the volume increases by 72.8%

The complete question is added at the end of this solution

From the question, we have the following parameters that can be used in our computation:

Length = l

Width = w

Height = h

The volume of a box can be calculated using

Volume = lwh

Rewrite the volume equation as

v = lwh

When the dimensions of the box are increased by 20%, we have the following expressions

Length = 1.2l

Width = 1.2w

Height = 1.2h

So, the new volume is

V = 1.2l * 1.2w * 1.2h

Evaluate

V = 1.728lwh

Hence, the expression is 1.728lwh

The two true options are A and D

The two options that are true about the graph that represents this real-world scenario are;

All the t values must be positive, and a viable solution is (10, 50). Hence, the correct option for this question is A and D.

Plotting the data in the graph is advantageous because it gives a visual presentation of the data and makes it easy to observe and forecast the large data set in a short time.

In the case of this question, the temperature is directly reliant on the c number of cricket chirps heard in 14 seconds. Therefore, if all the c values must be positive integers, the values of t must also be positive numbers.

t = c + 40

Because 10 is a positive integer, it is a possible c value

If c = 10

t = 40 + 10

t = 50

A viable solution (10, 50) represents the values of c and t, respectively, to predict the data more accurately and with validity.

Therefore, the correct option for this question is A and D.

What is an exponential function?

The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent.

An exponential function is a function that usually takes the form f(x) = bˣ.

The exponential curve depends on the exponential function and it depends on the value of the x.

where;

b = base

ˣ = power

The general exponential function that models  the data given is:

[tex]y = ce^{kt}[/tex]

According to the (5,5c)

The correct statement is "each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern. Each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern."

What is a statement?

A statement in mathematics is a declarative utterance that can only be either true or false. A proposal is another name for a statement. It's important that there be no ambiguity. A sentence can only be true or untrue and not both for it to be a statement.

Given that:

Martina used the rule “Add 2.”

Sabrina used the rule “Add 6.”

The rule that Martina is follow is

M(n) = starting number + 2n

M(n) = 0 + 2n

M(n) = 2n

The rule that Sabrina is follow is

S(n) = starting number + 6n

S(n) = 0 + 6n

S(n) = 6n

S(n) = 3 × 2n

S(n) = 3 × S(n)
