↣ Substitute all domains in the equation for the ranges.

[tex]12x+6y=24[/tex]    

[tex]2x+y=4[/tex]     ↣ Divide the whole equation by 6.

↣ Substitute x = -4 in the equation.

[tex]2(-4)+y=4\\-8+y=4\\y=4+8\\y=12[/tex]

Our range is 12 when x = -4. In the choice there is only one choice that has range value as 12. Therefore, the answer is B.

↣ If you want me to solve for all ranges then you can reply under this. Since there is only one choice that has 12 as range value, I decide not to continue. So If you want me to solve for all ranges then feel free to reply under this. ↣

Answer:

There is two ounces of water for every ounce of vegetables.

Step-by-step explanation:

Given that:

Sam needs 16 ounces of water and 8 ounces of vegetables to make 1 batch of vegetable soup.

Ratio is defined as the quantitative relation between two numbers.

We will use ratio to compare the amount of water to amount of vegetables.

Ratio of water to vegetables

16 : 8

Dividing by 8

[tex]\frac{16}{8}:\frac{8}{8}[/tex]

2:1

Hence,

There is two ounces of water for every ounce of vegetables.

The statement is correct. The product of a complex conjugate is always a real number.

Given, if neither a nor b are equal to zero then we have to conclude that which of the following statement accurately describes the product of (a + ib)(a - ib). So, let's proceed to solve the question accordingly.

Now, solve the product of (a + ib)(a - ib), we get

(a + ib)(a - ib) = a(a - ib)+ib(a - ib)

                     = a^2-iab+iab+(ib)^2

                     = a^2+i^2b^2

we know that, i^2 = -1, then

= a^2+i^2b^2 = a^2+b^2

⇒(a + ib)(a - ib) = a^2+b^2

∴ a^2+b^2 will always give a real number.

Therefore, option (d) is correct. The product of a complex conjugate is always a real number.

Step-by-step explanation:

Let's solve your equation step-by-step.

3/a(−2)−4=20

−4a−6/a=20

Step 1: Multiply both sides by a.

−4a−6=20a

−4a−6−20a=20a−20a(Subtract 20a from both sides)

−24a−6=0

−24a−6+6=0+6(Add 6 to both sides)

−24a=6

−24a/−24=6/−24

(Divide both sides by -24)

(Works in original equation)

Step-by-step explanation:

Consider an engineering material of initial length Lo, Area (A), Modulus of elasticity (E) and applied a force P due to which change in the length of the material is δ2 from it’s original length (Lo)

Initial length of the material is Lo. Hence, at time t = 0 when no force applied on the material the length of the material will not change (i.e., at time t=0, δ1 = 0)

Modulus of elasticity of the material:

[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

Area of the material:

[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

[tex]A=\frac{P \cdot L_{o}}{E\left[\delta_{2}-\delta_{1}\right]}[/tex]

Length of the material:

[tex]E=\frac{P \cdot L_{0}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]

Box C

Step-by-step explanation:

First switch the box that's in kilograms into grams. One kilogram=1000 grams. So box C is 1250 grams.

Next divide the amount in each box by the cost of each box.

Box A 500/173=2.89

Box B 750/260=2.88

Box C 1250/435=2.87

So, since box C has the lowest amount when divided, that box has the best value.

−6x − 15y − 14q − 21p

Step-by-step explanation:

Let's simplify step-by-step.

−3(2x+5y)−7(2q+3p)

Distribute:

=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)

=−6x+−15y+−14q+−21p

Answer:

=−21p−14q−6x−15y

The equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

−3(2x + 5y) − 7(2q + 3p)

For solving the equation we have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

First, open the bracket and multiply,

=−3(2x + 5y) − 7(2q + 3p)

=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)

=−6x+−15y+−14q+−21p

Rearrange the equation as

=−21p−14q−6x−15y

Thus, the equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

[tex]V_1=length\times breadth\times height[/tex]

[tex]V_1=(8)(6)(4)[/tex]

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

[tex]V_2=\dfrac{1}{3}\times length\times breadth\times height[/tex]

[tex]V_2=(\dfrac{1}{3})(8)(6)(6)[/tex]

The volume of composite figure is

[tex]V=V_1+V_2[/tex]

[tex]V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)[/tex]

It can be written as

[tex]V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)[/tex]

Therefore, the correct option is A.

Using a linear function, it is found that:

a) 36 ounces of food were there after 12 days.

b) It took 24 days for the bag to contain 16 ounces of food.

c) The bag weighed 56 ounces before it was opened.

d) It took about 33 days for the bag to be empty.

A linear function is defined according to the following rule:

y = mx + b

In which:

From the graph of the function, we have that:

Hence the function for the amount of food after t days is given by:

A(t) = 56 - 1.6667t.

After 12 days, the amount is given by:

A(12) = 56 - 1.6667(12) = 36 ounces.
