Thank me with a 5 star review (:

The solution is, Degree of functions y = x/2 - 5  is one, so, B: y equals one half x minus 5represents a linear function.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

we know that,

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

The degree of polynomials in one variable is the highest power of the variable in the algebraic expression.

The degree of linear function is always one.

Degree of functions y = x/2 - 5, is one.

Hence, B: y equals one half x minus 5represents a linear function.

Answer:  Jeremy will need 36 gallons of brown material and 12 gallons of green material.

explanation: I did the test and got the question right. hope this helps!

The correct choice is: Jeremy will need 30 gallons of brown material and 18 gallons of green material.

Brown Material: 12.75, 18.6, 24, E (E is missing, represents the unknown value)

Green Material: 4.25, B (B is missing, represents the unknown value), D (D is missing, represents the unknown value), 11.5

Total: A (A is missing, represents the unknown value), C (C is missing, represents the unknown value), 32, 46

We know that Jeremy needs a total of 48 gallons of compost. So, we can set up an equation:

A + C = 48

From the brown material data, the total brown material is 12.75 + 18.6 + 24 + E:

12.75 + 18.6 + 24 + E = A

From the green material data, the total green material is 4.25 + B + D + 11.5:

4.25 + B + D + 11.5 = C

Now, let's look at the given total values:

A + C = 32 + 46 = 78

We can now set up a system of equations:

12.75 + 18.6 + 24 + E = A ........(1)

4.25 + B + D + 11.5 = C ........(2)

A + C = 78 ........(3)

Now, to find the values of A and C, let's use equation (3):

A + C = 78

From the choices provided, let's try option (A) Jeremy will need 36 gallons of brown material and 12 gallons of green material.

If Jeremy needs 36 gallons of brown material, then A would be 36. Let's see if this fits:

A + C = 78

36 + C = 78

C = 78 - 36

C = 42

Now, let's check if this aligns with the green material:

4.25 + B + D + 11.5 = C

4.25 + B + D + 11.5 = 42

Now, B and D must be positive values, and they need to sum up to 42 - (4.25 + 11.5) = 26.25.

There are various combinations for B and D that satisfy this, such as B = 20 and D = 6.25, or B = 15 and D = 11.25.

But since none of the given values in the green material (4.25, 11.5) match these combinations, option (A) is not the correct answer.

Now let's try option (B) Jeremy will need 30 gallons of brown material and 18 gallons of green material.

Jeremy needs 30 gallons of brown material, then A would be 30. Let's see if this fits:

A + C = 78

30 + C = 78

C = 78 - 30

C = 48

Now, let's check if this aligns with the green material:

4.25 + B + D + 11.5 = C

4.25 + B + D + 11.5 = 48

Now, B and D must be positive values, and they need to sum up to 48 - (4.25 + 11.5) = 32.25.

One combination for B and D that satisfies this is B = 20 and D = 12.25.

Since the values 20 and 12.25 are among the given green material values, option (B) is the correct answer.

So, Jeremy will need 30 gallons of brown material and 18 gallons of green material.

Therefore, the correct choice is:

Jeremy will need 30 gallons of brown material and 18 gallons of green material.

The probability of landing on yellow is less than the probability of landing on blue.

Explanation:
The probability of landing on yellow is 2/8, while the probability of landing on blue is 3/8. 2/8 is less than 3/8
None of the other answers can be right, because:
the probability of landing on purple (2/8) is greater than the probability of landing on orange (1/8),
the probability of landing on orange (1/8) is less than the probability of landing on yellow (2/8),
and the probability of landing on purple (2/8) is less than the probability of landing on blue (3/8)

The ratio of girls to boys in your class is 18 girls : 12 boys, or in fraction form 18/12 or 3/2.

If the school has the same ratio throughout, the ratio of girls to boys in the entire school is 3 girls to 2 boys.

To find the number of girls in the school, you can use the equation:

(number of girls) / (number of students) = (3 girls) / (5 students)

Cross-multiplying, we get:

(number of girls) = (3 girls) / (5 students) * (2000 students)

Simplifying, we get:

(number of girls) = 1200

So, there are 1200 girls in the school.

Answer:

The y-intercept is (12,0).

The x-intercept is (0,2).

Step-by-step explanation:

• The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

• These can be easily found by rearranging the equation to standard slope format and plugging 0 into either variable.

• -24x - 4y = -48.

• -4y = -48 + 24x.

• Divide the entire equation by -4 to isolate y.

• Y = 12 - 6x.

• Plug 0 into x

 ○ Y = 12 - 6(0).

 ○ Y = 12.

• Plug 0 into y

 ○ 0 = 12 - 6x

 ○ 6x = 12

 ○ X = 2

The x intercept is (0,2)

The y intercept is (12,0)

Answer: For the $18 sweatshirt, DISCOUNT 2 is the best.

For the $30 sweatshirt, DISCOUNT 3 is the best.

Step-by-step explanation: For the $18 sweatshirt, 20% off would be $14.4. If she uses the $5 rebate, shes getting $5 off or back. She can't use the 3rd discount because it's not over $20.

For the $30 sweatshirt, 20% off of that makes it $24. $5 back from the rebate makes it $25, and half off (50%) makes it $15. Which is the cheapest.
