The given system of equations : 6x - y = 2 and 4x - y = -8.

6x - y = 2 ( 1 )

4x - y = -8 ( 2 )

for the value of y, use substitution method:

Solve the equation (1) for y :

6x - y = 2

y = 6x - 2

Susbtitute the value of y in the equation ( 2 )

4x - y = - 8

4x - (6x - 2) = - 8

4x - 6x + 2 = - 8

4x -6x = - 8 - 2

-2x = -10

Divide both side by ( -2)

-2x/(-2) = -10/(-2)

x = 5

Substitute x = 5 in the equation ( 1 )

6x - y = 2

6( 5 ) - y = 2

30 - y = 2

y = 30 - 2

y = 28

So, the value of y is 28

Answer : y = 28

If the volume of a rectangular prism with a height of 8 inches is 200 cubic inches and the base of the prism is a square, then the width of the rectangular prism is 5  inches

The volume of the rectangular prism = 200 cubic inches

The height of the rectangular prism = 8 inches

We know the volume of the rectangular prism = l×w×h

Where ls if the length of the base

w is the width of the base

h is the height of the rectangular prism

Given that the base of the prism is a square, then the length of the base is equal to width of the base

Consider

l = w = x

Substitute the values in the equation of volume

x × x × 8 = 200

[tex]x^{2}[/tex] × 8 = 200

[tex]x^{2}[/tex]  = 25

x = 5 inches

Hence, if the volume of a rectangular prism with a height of 8 inches is 200 cubic inches and the base of the prism is a square, then the width of the rectangular prism is 5 inches

The answers of the given questions are:

Given: There are 6 teaspoons of garlic powder and 15 teaspoons of salt in a triple batch of spice mix.

Let x be the teaspoons of salt.

Salt used with 8 teaspoons of garlic powder:

6/15 = 8/x

x = 20

Therefore, 20 teaspoons of salt is used with 8 teaspoons of garlic powder.

6 + 15 = 21 teaspoons of  spice mix

Salt used in 14 teaspoons of spice mix:

21/15 = 14/x

x = 10 teaspoons of salt.

Therefore, if there are 14 teaspoons of spice mix, 10 teaspoons of salt is there in it.

If 6 teaspoons of garlic powder are used then,

21-6 = 15 teaspoons of more salt is used

Therefore, 15 teaspoons of more salt is there than garlic powder if 6 teaspoons of garlic powder are used.

We will investigate how to determine the amount of money Mark started off with at the beginning off the day.

We will assume and declare a variable to Mark's bank balance at the beginning off the day:

Then mark sets out for movies and gets himself snacks to enjoy along his movies. The total receipt charged for his excursion is:

After his day expenses he will be left with a closing balance for the day. The closing balance of the day is expressed as:

We are given that mark was left with $12. This means:

Using the expression above we can write:

We will solve the above expression for initial balance ( P ) as follows:

Therefore, the answer is:

In order to add these two numbers, we need to add the algarisms that are in the same position.

Since the first number has 7 zeros and the second one has 8 zeros, the numbers 2 and 3 will not be added, since they are in different positions (the number 3 has more "value", since it's in a higher position).

So, adding these two numbers, we have:

Therefore the result of this sum is 320,000,000 (three hundred and twenty million).

The required sample size, using the z-distribution, is given as follows:

n = 253.

A confidence interval of proportions has the bounds given by the rule presented as follows:

In which the variables used to calculated these bounds are listed as follows:

The equation for the margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The confidence level is of 95%, hence the critical value z has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the margin of error are given as follows:

[tex]\pi = 0.22, M = 0.015[/tex]

Hence the required sample size is calculated as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.015 = 1.96\sqrt{\frac{0.015(0.985)}{n}}[/tex]

[tex]0.015\sqrt{n} = 1.96\sqrt{0.015(0.985)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.015(0.985)}}{0.015}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.015(0.985)}}{0.015}\right)^2[/tex]

n = 253. (rounding up, as a sample size of 252 would result in a margin of error slightly above 1.5%).

Answer:5.50 & $6

Step-by-step explanation:

Each bag of popcorn is $5.50 and the drink is $6.

Liam went into a movie theater and bought 9 bags of popcorn and 8 drinks costing a total of $97.50. This will be:

9p + 8d = 97.50

Jacob went into the same movie theater and bought 5 bags of popcorn and 4 drinks, costing a total of $51.50. This will be:

5p + 4d = 51.50

where P = popcorn

d = drink

The equations will be:

9p + 8d = 97.50

5p + 4d = 51.50

Multiply equation i by 5

Multiply equation ii by 9

45p + 40d = 487.50

45p + 36d = 463.50

Subtract

4d = 24

Divide.

d = 24/4

d = 6

Drink = $6

Since 9p + 8d = 97.50

9p + 8(6) = 97.50

9p + 48 = 97.50

9p = 97.50 - 48

p = $5.50

Popcorn cost $5.50.

To use the three theorems of similarity:

There are 3 theorems for proving triangle similarity:

AA Theorem

SAS Theorem

SSS Theorem

SAS Theorem

What happens if we only have side measurements, and the angle measures for each triangle are unknown? If we can show that all three sides of one triangle are proportional to the three sides of another triangle, then it follows logically that the angle measurements must also be the same.

SSS Theorem

Or what if we can demonstrate that two pairs of sides of one triangle are proportional to two pairs of sides of another triangle, and their included angles are congruent?

AA Theorem

As we saw with the AA similarity postulate, it’s not necessary for us to check every single angle and side in order to tell if two triangles are similar. Thanks to the triangle sum theorem, all we have to show is that two angles of one triangle are congruent to two angles of another triangle to show similar triangles.

Answer: Maximum height reached is 804.88 m

Step-by-step explanation:

At maximum height velocity is zero

We have equation of motion v² = u² + 2as

    Initial velocity, u = 320 ft/s = 97.536 m/s

    Final velocity, v = 0 m/s    

    Acceleration, a = -9.81 m/s²

    Substituting

                     v² = u² + 2as

                     0² = 97.536² + 2 x  -9.81 x s

                     s = 484.88 m

   So the arrow further a height of 484.88 m

Total height = 320 + 484.88 = 804.88 m

The equation is (x+1)²-4.

Here the graph is in the form parabola, where the parabola is basically a graph for a quadratic function which is a  curve in such an order that a point on it is equidistant from a fixed point called the focus of the parabola,  and a fixed line called the directrix of the parabola. The general formula for a parabola is: y = a(x-h)² + k , where (h,k) signifies the vertex whereas the standard equation of a  parabola is y² = 4ax.

For the given graph the vertex is  (h,k)=(-1,-4)

so the equation for the parabola  is

=>y= a(x+1)^²-4 .......1

Since we can see the parabola intercept  at the x-axis at point (1,0), putting those in the above equation :

=>0=a(1+1)^2-4

=>4=a(2)^2

=>a=1

So, substituting the value of an in equation 1, we get

The expression given as [x²+ 5x + 4]/[x² + 8x + 16] - [x² - 3x - 4]/[x²-16] simplifies to 0

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

[x²+ 5x + 4]/[x² + 8x + 16] - [x² - 3x - 4]/[x²-16]

Factorize the expression

So, we have

[x²+ 5x + 4]/[x² + 8x + 16] - [x² - 3x - 4]/[x²-16] = [(x + 4)(x + 1)]/[(x + 4)(x + 4)] - [(x - 4)(x + 1)]/[(x + 4)(x - 4)]

Simplify the common factors

So, we have

[x²+ 5x + 4]/[x² + 8x + 16] - [x² - 3x - 4]/[x²-16] = [(x + 1)]/[(x + 4)] - [(x + 1)]/[(x + 4)]

The terms of the above equation are the same

So, the result of subtracting one from the other is 0

This gives

[x²+ 5x + 4]/[x² + 8x + 16] - [x² - 3x - 4]/[x²-16] = 0
