Which expression is equivalent to ?

The system of equations with y = -4x and y = 2x + 3 has no solution.

The system of equations with y = -4x and y = 2x + 3 has no solution. To determine this, we can set the two equations equal to each other and solve for x:

-4x = 2x + 3

Adding 4x to both sides, we get:

0 = 6x + 3

Subtracting 3 from both sides, we get:

-3 = 6x

Dividing both sides by 6, we get:

-1/2 = x

Substituting x = -1/2 back into either equation will result in a false statement, indicating that the system has no solution.

Answer: Area of Square = 81m^2

Step-by-step explanation:

To find the area of a square you just need to know the side length on one side, and since we know that the perimeter is 36, and all sides of a square are equal we can divide 36/4, to get 9 is your side length.

Now to actually find the area you can just square your side length, so basically 9x9, which gives you 81, your answer!!

Answer:

Area = 81m^2

Step-by-step explanation:

Square has 4 equal sides so 36/4 =  9

9(9) = 81

y=4

the values of x changes while the y doesn't so it's y=4

Answer:

[tex]y=4[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

The equation of the line in Standard form is:

 [tex]Ax + By =C[/tex]

Where A, B, and C are integers.

We can find the slope of this line with this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given the points K(6, 4) and L(-6, 4), we get:

[tex]m=\frac{4-4}{-6-6}=0[/tex]

Substituting the value of "m" and the coordinates of any point on the line into the equation and solving for "b", you get:

[tex]4=0(6)+b\\b=4[/tex]

Therefore, the equation of this line is:

[tex]y=4[/tex]

Answer:

Option C) 4

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In this problem

The equation of the line represented a direct variation

The value of k is equal to [tex]k=y/x[/tex]

we have the points

(1,n) and (n,16)

so

[tex]k=n/1[/tex]

[tex]k=16/n[/tex]

equate

[tex]n/1=16/n[/tex]

solve for n

[tex]n^{2}=16\\ \\n=(+/-)4[/tex]

therefore

The value of n could be 4 or -4

To find the value of n, substitute the given points into the equation y=kx and solve for n. The possible value of n is 4.

To find the value of n, we need to use the given points and equation. Since the line passes through (1,n), we can substitute these values into the equation y=kx to get n=k(1) or n=k. Similarly, substituting the values (n,16) into the equation gives us 16=k(n). By equating these two equations, we can solve for k and n.

Using substitution, we have n=16/n. Solving this equation by multiplying both sides by n, we get n^2=16. Taking the square root of both sides, we have n=±4. Therefore, the value of n that could be possible is 4.

The in-line skates will cost $99.891 with the discount.

To find the cost of the in-line skates with the discount, we need to calculate the amount of the discount first. The discount is 10% of the original price, which is $110.99. To calculate the discount amount, we can multiply the original price by 0.10. The discount would be $110.99 x 0.10 = $11.099. The discounted price would be the original price minus the discount amount, so the discounted price would be $110.99 - $11.099 = $99.891.

Answer:

T.A. = 144 + 36√3

Step-by-step explanation:

The pyramid has a regular triangle for a base.  The other three faces are isosceles triangles.

The height of base can be found by dividing it into two right triangles.  We can either use properties of a 30-60-90 triangle, or use Pythagorean theorem.

h = 6√3

So the area of the base is:

A = 1/2 bh

A = 1/2 (12)(6√3)

A = 36√3

Similarly, the height of the three isosceles triangles can be found by dividing them into two right triangles and using Pythagorean theorem.

h = √(10² - 6²)

h = 8

So the area of the isosceles triangles is:

A = 1/2 bh

A = 1/2 (12)(8)

A = 48

So the total surface area of the pyramid is:

T.A. = 3(48) + 36√3

T.A. = 144 + 36√3

Answer:

[tex]a_{11} = 14336[/tex]

Step-by-step explanation:

The general formula for the twelfth term of a geometric sequence is:

[tex]a_n = a_1(r)^{n-1}[/tex]

Where [tex]a_1[/tex] is the first term and r is the common ratio

In this case we know that:

[tex]a_1 = 14\\r=-2[/tex]

The equation is:

[tex]a_n = 14(-2)^{n-1}[/tex]

So for [tex]n = 11[/tex] we look for [tex]a_{11}[/tex]

[tex]a_{11} = 14(-2)^{11-1}[/tex]

[tex]a_{11} = 14(-2)^{10}[/tex]

[tex]a_{11} = 14336[/tex]

Answer:

[tex]11^{th}[/tex] term = 14336

Step-by-step explanation:

We are given the first term [tex] a _ 1 = 1 4 [/tex] and  common ratio [tex] r = - 2 [/tex] of a geometric sequence and we are to find the [tex]11^{th}[/tex] term of this sequence.

We know that the formula to find the [tex]n^{th}[/tex] term in a geometric sequence is given by:

[tex]n^{th}[/tex] term = [tex] a r ^ { n - 1 } [/tex]

Substituting the given values in the above formula:

[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{11-1}[/tex]

[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{10}[/tex]

[tex]11^{th}[/tex] term = 14336

Answer:

90

Step-by-step explanation:

13.5/.15

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

15 is a percent and percent's are always taken out of the 100. This means that one proportion will have 15 as the part and 100 as the whole

We want to know out of what number is 13.5 15% of. This means 13.5 is the part and the unknown (let's make this x) is the whole.

[tex]\frac{13.5}{x} =\frac{15}{100}[/tex]

Now you must cross multiply

13.5*100 = 15*x

1350 = 15x

To isolate x divide 15 to both sides

1350/15 = 15x/15

90 = x

This means that 15% of 90 is 13.5

Answer: You will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.

Step-by-step explanation:

Knowing that you have 1-quart containers, you need to make the conversion from quarts to liters. This is:

[tex]1\ quart=0.946\ liters[/tex]

Now, since the gearbox holds 16.3 liters of oil, you can divide the volume of oil the gearbox holds by the volume of a container  (which is 0.946 liters or 1-quart) to calculate how many containers of 1-quart you will need to fill the gearbox with 16.3 liters of oil.

 [tex]number\ of\ containers=\frac{16.3\ liters}{0.946\ liters}=17.2[/tex]

Based on the result, you will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.

You will need 17 one-quart containers of oil to fill the 16.3-liter gearbox.

To determine how many 1-quart containers of oil you will need to fill the 16.3-liter gearbox, we can convert the 16.3 liters to quarts by using the conversion factor of 1 liter = 1.05668821 quarts. So, 16.3 liters would be approximately 17.229 quarts. Since each 1-quart container holds exactly 1 quart of oil, you will need 17 of the 1-quart containers to fill the gearbox with 16.3 liters of oil.

Given 4 yards of ribbon and each package requires 2/3 yard, Kris can wrap 6 packages.

This question is about dividing total resources, in this case, ribbon, by the amount needed for each unit, in this case, a package. Kris has 4 yards of ribbon, and each package requires 2/3 yard of ribbon to wrap. To find out how many packages Kris can wrap, we need to do a division: total yards of ribbon ÷ yards of ribbon per package.

The equation for this would be: 4 ÷ 2/3. When we divide by a fraction, we multiply by its reciprocal. The reciprocal of 2/3 is 3/2, so we set up the equation like this: 4 x (3/2).

The answer to this equation is 6. Hence, Kris can wrap 6 packages with 4 yards of ribbon.

Answer:

The measure of one exterior angle is 45 degrees.

Step-by-step explanation:

The formula to find exterior angle of and shape is 360 degrees divided by n (number of sides the shape has). 360 divided by 8 = 45 degrees.

Answer:

Exterior angle = 45°

Step-by-step explanation:

We know that the sum of exterior angles of a polygon is 360 degrees.

Since here we a regular polygon with eight sides (which makes it an octagon) so this means that the interior angles each would be equal to:

[tex]\frac{(n - 2) \times 180}{n} \\ \frac{(8 - 2) \times 180}{8}\\ \frac{6 \times 180}{8} \\ \frac{1080}{8} [/tex] = 135 degrees

We know that each interior angle is supplementary to the exterior angle at the vertex.

So each exterior angle = [tex]180-135[/tex] = 45 degrees

Answer:

about 50 000 i think sorry if this didnt hep

Step-by-step explanation:

To calculate the previous population before a 15% increase that resulted in a current population of 59,800, we use the formula: Previous Population = Current Population / (1 + Percentage Increase), which yields a previous population of approximately 52,000.

The question pertains to determining what the previous population of a city was before it experienced an increase of 15%. Given that the current population is 59,800, we can calculate the previous population using the formula:

Current Population = Previous Population * (1 + Percentage Increase)

To find the Previous Population, we rearrange this formula:

Previous Population = Current Population / (1 + Percentage Increase)

By substituting in the given values:

Previous Population = 59,800 / (1 + 0.15)

Previous Population = 59,800 / 1.15

Previous Population = 52,000 (approximately)

Therefore, the previous population of the city was around 52,000 inhabitants before the 15% increase.
