1 . First we will write the term having highest degree and then move to lowest degree,

→ 7 (y -5 x)² + x -3 x+2+5

2. Adding and subtracting like terms

→7 (y -5 x)² - 2 x+7

Expanding the term in brackets

→ 7(y² + 25 x² -10 x y) - 2 x + 7

Use distributive property

→ 7 y² + 175 x² -70 x y -2 x +7→[Wrote the terms from highest degree to lowest degree]

Answer:

68

Step-by-step explanation:

Let:

Number of girls invited = x

Number of boys = x +20

3/4 of boy showed up

2/3 of girls showed up

Exactly 19 did not show up

Therefore, we could say:

Fraction of boys that didn't show up = 1 - 3/4 = 1/4

Fraction of girls that didn't show up = 1 - 2/3 = 1/3

That is,

[1/4 *(x + 20)] + [1/3*x] = 19

[(x + 20) / 4] + x /3 = 19

(3(x + 20) + 4x) / 12 = 19

3x + 60 + 4x = 228

7x = 228 - 60

7x = 168

x = 168 / 7

x = 24

Number of girls, x = 24

Number of boys, x + 20 = 24 + 20 = 44

Total friends invited = (24 + 44) = 68

Answer:

300π or 942.477796077 cubic feet

Step-by-step explanation:

25π*12=300π

The approximate volume of the given cylinder is 942.48 ft³.

The volume of the cylinder is the density which signifies the amount of substance it can hold.

Mathematically,

                        V = πr²h

where, r is the radius of the cylinder

and h is the height of the cylinder.

It is given that,

Height h of the cylinder = 12 ft

Diameter d of the cylinder = 10 ft

⇒ Radius r = d/2

⇒ r = 10/2

⇒ r = 5 ft

Now, Volume of the cylinder V = πr²h

Putting the values of r and h of given cylinder. We get,

⇒ V = 3.14 × (5 ft)² × 12ft

⇒ V = 3.14 × 25 ft² × 12 ft

⇒ V = 3.14 × 300 ft³

⇒ V ≈ 942.48 ft³

The approximate volume of the given cylinder is 942.48 ft³.

Answer:

f(x)=-2x+5

Step-by-step explanation:

The line shown in the graph is always decreasing at a constant rate, has a slope of -2, and has a y-intercept of 5.

So the parent function has been reflected across the x-axis (multiplied by -1), vertically stretched by a factor of 2 (multiplied by 2), and vertically translated up 5 units (5 added to it).

Therefore, the slope-intercept equation that represents this linear function is f(x)=-2x+5.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the given line is y=-2x+5.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The given line passes through two points with coordinates (0,5) and (1,3). Therefore, the slope and the y-intercept of the given equation of a line can be written as,

Slope, m = (5 - 3)/(0 - 1) = 2/-1 = -2

y-intercept, c = 5

Now, the equation of the line can be written as,

y = mx + c

y = -2x + 5

Hence, the equation of the given line is y=-2x+5.

Answer:

Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1.

Step-by-step explanation:

Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1.

We have given that,Trapezoid ABCD is shown on the coordinate grid. Trapezoid ABCD is dilated with the origin as the center of dilation using the rule (x, y)→(0.4x, 0.4y) to create trapezoid A'B'C'D'.

We have to find the correct statement.

If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.

Therefore from the given we can conclude that the statement,

If the scale factor is between 0 and 1, the image is a reduction

Therefore,Trapezoid A'B'C'D' is smaller than trapezoid ABCD because the scale factor is less than 1 is correct.

Answer:

The equation for the general term of the sequence is:

[tex]a_{n} = -6(-\frac{2}{3})^{n-1}[/tex]

The sequence converges to 0.

Step-by-step explanation:

First, we need to find the formula for the general term of the sequence, which is a geometric sequence, meaning that it has a common ratio, given by:

[tex]r = \frac{4}{-6} = \frac{-\frac{8}{3}}{4} = -\frac{2}{3}[/tex]

The equation of a geometric sequence has the following format:

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

In which [tex]a_{1}[/tex] is the first term.

In this question, we have that [tex]a_{1} = -6, r = -\frac{2}{3}[/tex]. So, the equation for the general term is:

[tex]a_{n} = a_{1}(r)^{n-1} = -6(-\frac{2}{3})^{n-1}[/tex]

To find if the sequence converges, we find the limit of [tex]a_{n}[/tex] as [tex]n \rightarrow \infty[/tex]. So

[tex]\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} -6(-\frac{2}{3})^{n-1} = -6(-\frac{2}{3})^(\infty) = 0[/tex]

A number between 0 and 1 elevated to infinity tends to 0, so the sequence converges to zero.

The required nth term is [tex]a_n=a(-\frac{2}{3} )^n[/tex]

The Geometric series formula or the geometric sequence formula gives the sum of a finite geometric sequence.

Given that,

First Term=[tex]-6[/tex]

Common Ratio is,

[tex]\frac{4}{-6}=\frac{2}{-3} \\\frac{4}{\frac{-8}{3} }= \frac{2}{-3}[/tex]

So, the given sequence is in a geometric sequence.

So, the nth term of the given series is,

[tex]a_n=ar^{n-1}\\=-6(-\frac{2}{3} )^{n-1}\\a_n=a(-\frac{2}{3} )^n[/tex]

Answer:

The sequence diverges.

Step-by-step explanation:

A sequence [tex]a_{n}[/tex] converges when [tex]\lim_{n \rightarrow \infty} a_{n}[/tex] is a real number.

In this question, the sequence given is:

[tex]a_{n} = 4n\cos{(7n\pi)}[/tex]

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as: [tex]a_{n} = 4n[/tex]. So

[tex]\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} 4n = \infty[/tex]

Since the limit is not a real number, the sequence diverges.

Answer:

three factors

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Find the system for 2x+3y=5 and 3x+y=6 using substition.

I will solve your system by substitution.

(You can also solve this system by elimination.)

3x+y=6;2x+3y=5

Step: Solve3x+y=6for y:

3x+y+−3x=6+−3x(Add -3x to both sides)

y=−3x+6

Step: Substitute−3x+6foryin2x+3y=5:

2x+3y=5

2x+3(−3x+6)=5

−7x+18=5(Simplify both sides of the equation)

−7x+18+−18=5+−18(Add -18 to both sides)

−7x=−13 (Divide both sides by -7)

x=[tex]\frac{13}{7}[/tex]

Step: Substitute [tex]\frac{13}{7}[/tex] forxiny=−3x+6

y=−3x+6

y=−3([tex]\frac{13}{7}[/tex])+6

y=[tex]\frac{3}{7}[/tex]

2. Let's solve your system by elimination.

3x+y=6;2x+3y=5

Multiply the first equation by -3,and multiply the second equation by 1.

−3(3x+y=6)

1(2x+3y=5)

Becomes:

−9x−3y=−18

2x+3y=5

Add these equations to eliminate y:

−7x=−13

Then solve−7x=−13for x:

−7x=−13 (Divide both sides by -7)

x=[tex]\frac{13}{7}[/tex]

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

3x+y=6

Substitute[tex]\frac{13}{7}[/tex] forxin3x+y=6

3([tex]\frac{13}{7}[/tex])=6 (Simplify both sides of the equation)

y+39/7+−39/7=6+−39/7 (Add (-39)/7 to both sides)

y=[tex]\frac{3}{7}[/tex]
