Step-by-step explanation:

(A) Subtracting the right side from both sides, we get ...

... (20 -4x) -(12 -x +8 -3x) = 0

... (20 -12 -8) +x(-4 +1 +3) = 0

... 0 = 0 . . . . . true for all values of x (infinite solutions)

(B) Subtracting the right side from both sides, we get ...

... (5x +4x -3) -(24 +8x) = 0

... x(5 +4 -8) +(-3 -24) = 0

... x -27 = 0

... x = 27 . . . . . . (one solution)

(C) Subtracting the right side from both sides, we get ...

... (5x +6) -(2x +6 +3x -15) = 0

... x(5 -2 -3) +(6 -6 +15) = 0

... 15 = 0 . . . . . . . not true for any value of x (no solutions)

Tony because he spent $19 while Mario spent $18. To explain, you would multiply 3 by $4 because Tony bought 3 of the $4 packs of pencils. Therefore, he would have spent $12. In addition, add $7 to $12, you get $19. On the other hand, Mario bout 4 of the $6 binders. That would mean he spent $24 on binders However, he had a $6 coupon which means he can take $6 off the total price of $24. That would mean subtracting $6 from $24. That would get Mario $18

Line segment of length k is divided into 3 equal parts.

so first segment is 0-k/3 and third segment is 2/3k-k

so mid-pt of 1st = k/6 and 3rd = 5/6k

so the distance in between = 5/6k-k/6 = 4/6k = 2/3k

ans is A

The distance between the midpoints of the first segment and the third segment is 2k/3. Hence, option A is the right choice.

The mid-point of a line segment is the point from which the distance to both ends of the line segment is equal.

In the question, we are given a line segment of length k units, which is divided into 3 equal parts.

We are asked to find the distance between the midpoints of the first and third segments.

Firstly, we divide the line segment at points k/3 and 2k/3, to get three equal parts of lengths k/3 each.

Now, the mid-point of the first segment = (0 + k/3)/2 = k/6.

The mid-point of the third segment = (2k/3 + k)/2 = 5k/6

Therefore, the distance between the midpoints of the first segment and the third segment is (5k/6 - k/6) = 4k/6 = 2k/3. Hence, option A is the right choice.

Answer:

23

Step-by-step explanation:

The notation (f∘g)(1) means f(g(1)). We can first find g(1), then use that value as the argument to the f function.

g(1) = 2·1-6 = -4

f(-4) = -4(-4)+7 = 16+7 = 23

Answer: First option. y-15=5(x-3)

Solution:

We can take any pair of points of the table. For example:

P1=(3, 15)=(x1, y1)→x1=3, y1=15

P2=(5, 25)=(x2,y2)→x2=5, y2=25

And we can find the slope m using the following formula:

m=(y2-y1)/(x2-x1)

m=(25-15)/(5-3)

m=(10)/(2)

m=5

Now we can apply the point-slope formula to find the equation of the right line:

y-y1=m(x-x1)

Replacing y1=15, m=5, and x1=3

y-15=5(x-3)

The equation in point-slope form that represents the plant's growth over time would be 'y - 9 = 3x', given that the y-intercept is 9 and the slope is 3.

Based on the information given, it is clear that the y-intercept where the line intersects the y-axis is 9 and the slope of the line is 3. We know that y stands for the height of the plant and x for time in months. Using these values, the equation in point-slope form, which is normally written as y - y1 = m(x - x1) where m is the slope and (x1, y1) is a given point on the line, can be simplified assuming that x1=0 and y1 is our y-intercept which is 9.

Therefore, the equation of the line that represents the growth of the plant over time in point-slope form would be y - 9 = 3x.

There is an obvious factor of x², so we can reduce this to the problem of finding zeros of a quadratic by factoring that out. Then, we can determine the zeros of the quadratic factor to complete the finding of zeros for the function.

A factor of x² can be factored out, leaving ...

... f(x) = x²(x² +x +4)

The latter factor has only complex zeros. It can be rewritten by completing the square.

... x² +x +4 = (x² +x +1/4) +(3 3/4) = (x +1/2)² +(3 3/4)

So, the real zeros are where x² = 0, at x = 0. The complex zeros are where the above expression is zero, ...

... (x +0.5)² +3.75 = 0

... (x +0.5)² = -3.75

... x + 0.5 = √-3.75 = ±0.5i√15

... x = -0.5(1 ±i√15)

The function zeros are 0 (multiplicity 2) and -0.5±0.5i√15.

Final answer:

The function y=2x+13 takes on a positive value for x > -6.5 and a negative value for x < -6.5.

Explanation:

The function y=2x+13 represents a linear equation. To find the values of x for which the function takes on a positive value, we need to solve the inequality 2x+13 > 0.

Subtracting 13 from both sides gives 2x > -13.

Dividing both sides by 2, we get x > -6.5.

Therefore, for x values greater than -6.5, the function will be positive.

To find the values of x for which the function takes on a negative value, we need to solve the inequality 2x+13 < 0. Subtracting 13 from both sides gives 2x < -13.

Dividing both sides by 2 and flipping the inequality sign, we get x < -6.5.

Therefore, for x values less than -6.5, the function will be negative.

DC = [tex]\frac{5}{2}[/tex] = 2.5

since the triangles are similar then the ratios of corresponding sides are equal

[tex]\frac{AC}{AD}[/tex] = [tex]\frac{BC}{DE}[/tex]

[tex]\frac{7.5+DC}{7.5}[/tex] = [tex]\frac{8}{6}[/tex] (cross-multiply )

45 + 6DC = 60

6DC = 60 - 45 = 15 ( divide both sides by 6 )

DC = [tex]\frac{5}{2}[/tex]

21.6 units

Calculate the length of the 2 inclined sides using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 3 ) and (x₂, y₂ ) = (3, 4 )

d = √(3 + 3 )² + (4 - 3)² = √(36 + 1 ) = √37

repeat for (x₁, y₁ ) = (- 3, 3 ) and (x₂, y₂ ) = (3, - 3 )

d = √(3 + 3 )² + (- 3 - 3 )² = √(36 + 36 ) = √72

the vertical side has a length of 7 units

perimeter = √37 + √72 + 7 = 21.6 ( nearest tenth of a unit )

The perimeter of the triangle shown on the coordinate plane is 15.5 units

The perimeter of the triangle is the sum of the lengths of its three sides. To find the lengths of the sides, we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

The coordinates of the three points are:

A = (0, 0)

B = (10, 0)

C = (5, 10)

The length of side AB is:

distance from A to B = sqrt((10 - 0)^2 + (0 - 0)^2) = sqrt(10^2) = 10

The length of side BC is:

distance from B to C = sqrt((5 - 10)^2 + (10 - 0)^2) = sqrt((-5)^2 + 10^2) = sqrt(125) = 5 \sqrt{5}

The length of side AC is:

distance from A to C = sqrt((5 - 0)^2 + (10 - 0)^2) = sqrt(5^2 + 10^2) = sqrt(125) = 5 \sqrt{5}

Therefore, the perimeter of the triangle is:

perimeter = AB + BC + AC = 10 + 5 \sqrt{5} + 5 \sqrt{5} = 10 + 10 \sqrt{5}

To the nearest tenth of a unit, the perimeter of the triangle is 15.5 units.

Therefore, the answer is 15.5 units.

Answer:

Your answer is 16√3 units2

Step-by-step explanation:

A) The price elasticity of demand is given by

... Ed = (dx/dp)·(p/x)

... = -250·(15/(9500-250·15)) ≈ -0.652

B) This value has a magnitude less than 1, so price can be increased to increase revenue.

_____

The price at which Ed has a magnitude of 1 is ...

... 250p/(9500 -250p) = 1

... 250p = 9500 -250p

... 500p = 9500

... p = 9500/500 = 19

Revenue will increase as price increases up to $19 per pair.

The nth term of the sequence is given by

[tex]U_n=a+(n-1)d [/tex]

Where

[tex]a[/tex]

is the first term and

[tex]d[/tex]

is the constant difference.

We were given that,

[tex]a=6[/tex]

S we just need the common difference to write the nth term.

We can get that from another information given to us.

We were also given that the 4th term is 6. This gives the equation.

[tex]a+3d=-6[/tex]

We substitute

[tex]a=6[/tex]

to obtain

[tex]6+3d=-6[/tex]

Or

[tex]2+d=-2[/tex]

This implies,

[tex]d=-2-2[/tex]

[tex]d=-4[/tex]

We substitute these values into the general formula to obtain,

[tex]U_n=6+(n-1)\times-4[/tex]

This gives us,

[tex]U_n=6+-4n+4[/tex]

[tex]U_n=10-4n[/tex]

Hence the nth term of the sequence is,

[tex]10-4n[/tex]

[tex]a_{n}[/tex] = 10 - 4n

this is an arithmetic sequence with n th term

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1 )d

where [tex]a_{1}[/tex] is the first term and d the common difference

given [tex]a_{4}[/tex] = - 6, then

6 + 3d = - 6 ( subtract 6 from both sides )

3d = - 12 ( divide both sides by 3 )

d = - 4 ← common difference hence

[tex]a_{n}[/tex] = 6 - 4 (n - 1 ) = 6 - 4n + 4 = 10 - 4n
