Answer:

1, 3

Step-by-step explanation:

1. x > x

Technically, one number cannot be more than itself. It can only equal to itself.

3. –4 + x > –2 + x

If you minus x from both sides of the equation, it becomes:

-4 > -2

This is not true no matter what x is, thus it has no solution.

4. x – 2 < x + 3

If you add 2 on both sides, it becomes:

x < x + 5

This inequality is possible and has infinitely many solutions.

Note: I will update this answer and address Question 2 once the inequality sign is given :)

Answer:  Part 1: y =10x+50

Part 2:  Jordan’s total cost = $90

Step-by-step explanation:

Given: Price of each large balloon = $25

Price of each small balloon = $10

Price of 2 large balloons = 2 (Price of each large balloon)

= $2 (25)

= $50

Part 1: Total cost = (Number of small balloons)(Price of each small balloon)  +  (Number of large balloons)(Price of each large balloon)

Let x = Number if small balloons , y=  total cost Jordan must pay in dollars.

Then, y= (x)(10)+(2)(25)

⇒ y =10x+50

Part 2: If she purchases 4 small balloon animals, put x=4

Then, y= 10(4)+50=40+50= 90

i.e. Jordan’s total cost = $90

Answer:

4. The solution to the system of equations is: (2,-1)

5. The solution to the system of equations is: (3,5)

Step-by-step explanation:

4. What is the solution to the system of equations?

[tex]2x+3y=1\\-3x+4y=-10[/tex]

Let:

[tex]2x+3y=1--eq(1)\\-3x+4y=-10--eq(2)[/tex]

Multiply eq(1) by 3 and eq(2) by 2 and add both equations

[tex]6x+9y=3\\-6x+8y=-20\\---------\\0x+17y=-17\\y=\frac{-17}{17}\\y=-1[/tex]

So, value of y=-1

Now finding the value of x bu putting value of y in eq(1)

[tex]2x+3y=1\\2x+3(-1)=1\\2x=1+3\\2x=4\\x=\frac{4}{2}\\x=2[/tex]

So, value of x=2

The solution to the system of equations is: (2,-1)

5. What is the solution to the system of equations?

[tex]y=2x-1\\6x-y=13[/tex]

Let:

[tex]-2x+y=-1--eq(1)\\6x-y=13--eq(2)\\------\\4x=12\\x=\frac{12}{4}\\x=3[/tex]

So, value of x=3

Putting value of x in equation 1 to find value of y

[tex]y=2x-1\\y=2(3)-1\\y=6-1\\y=5[/tex]

So, value of y=5

The solution to the system of equations is: (3,5)

Answer:

  A) the curves are ellipses

  B) 161 yards

  C) 366 yards

Step-by-step explanation:

A) The general shape of the side marked c has the appearance of two quarter-ellipses. The major axis is approximately 125 yards, and the minor axis is approximately 80 yards. Paul could assume that the curves are quarter-ellipses.

__

B) For an ellipse with this eccentricity, its perimeter is within 2% of that of a circle with a diameter equal to the average of these dimensions.*

So, the approximate length of side c is ...

  c ≈ π(80 +125)/4 ≈ 161 . . . . yards; length of side c

__

C) The perimeter of the pond is the sum of the side lengths, so will be ...

  80 yds + 125 yds + 161 yds = 366 yds . . . pond perimeter

_____

* Indian mathematician Ramanujan developed an approximate formula for the circumference of an ellipse, which would otherwise need to be computed using an elliptic integral. it is ...

  C = π(a+b)(1 + 3λ²/(10 +√(4 -3λ²))

where λ = (a -b)/(a +b) and a, b are the semi-axis lengths.

For this ellipse, λ = 9/41, so the last factor is about 1.01208313. Using this factor, the circumference is expected to be good to about 7 significant digits. Continuing the calculation, we find ...

  C ≈ 325.904 . . . . circumference of an ellipse 125 yd long by 80 yd wide

This is twice the length we imagine for c, so c ≈ 163 yards. As we said, the approximation used above is within 2% of this value.

The attachment shows the shape if the curve is actually an ellipse.

X is -18

Answer:

y = x - 1

Step-by-step explanation:

If it's parallel to x - y = 7, that means the slope of that equation is the slope for the equation you're looking for.  

To get the slope, you need to put the given equation into slope intercept form, so move x to the other side. You should get: -y = 7 - x

Then, to get the y positive, divide by -1:     y = -7 + x

Slope intercept form is as follows: y = mx + b, so whatever the number is in front of x is your slope. In this instance, your slope is 1.

You now have your slope, and a point in which your new line passed through. Using slope intercept form, y = mx + b, if you substitute in what you know, you can find your answer. Right now you know y, m, and x, and you're looking for b.  

x=1; y=0; m=1.  

So, substituting, you'd get 0 = (1)(1) + b

0=1+b     Solve

You should get b= -1, leaving your final answer as y = x - 1

y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

The slope will be same as it is parallel.

x - y = 7.

-y=7-x

y=x-7

Slope is 1.

Now equation of line passing through (1,0)

0=1(1)+c

c=-1

y=x-(-1)

y=x+1

Hence y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

Answer:

Perimeter = 15

Step-by-step explanation:

We are told that the length of each of the 3 sides of the triangle are consecutive odd integers.

Thus means that we can write the 3 terms as;

(x - 2), x, (x + 2)

Thus, perimeter is;

P = (x - 2) + x + (x + 2)

P = 3x

If an angle is 120°, it means that the corresponding side that is directly opposite the angle is the largest side of the triangle.

Thus, this side is (x + 2)

Using cosine rule, we have;

(x + 2)² = x² + (x - 2)² - 2(x(x - 2))cos 120

Expanding, we have;

x² + 4x + 4 = x² + x² - 4x + 4 - (2x² + 4x)(-½)

This reduces to;

4x = x² - 4x + x² - 2x

2x² = 10x

2x = 10

x = 10/2

x = 5

Thus, other sides are;

(x - 2) = 5 - 2 = 3

And (x + 2) = 5 + 2 = 7

So,perimeter is;

P = 3x = 3 × 5 = 15

Equation of a line through (15, 8) that is perpendicular to the line y =57 x −1 is [tex]\mathbf{y=-\frac{1}{57}x+\frac{157}{19}}[/tex]

Step-by-step explanation:

We need to write an equation of a line through (15, 8) that is perpendicular to the line y =57 x −1.

The equation will be in slope-intercept form: [tex]\mathbf{y=mx+b}[/tex]

Where m is slope and b is y-intercept.

Finding Slope of new line

We are given equation [tex]y =57x-1[/tex] of line, which is perpendicular to the line whose equation we need to find.

If the lines are perpendicular there slopes are inverse of each other i.e [tex]m_1=-\frac{1}{m_2}[/tex]

Slope of given line is m= 57 ( compare the given equation with standard slope-intercept form the value of m is 57

Slope of new line is m= [tex]-\frac{1}{57}[/tex]

Finding y-intercept of new line

Now finding y-intercept (b) for new line. It can be found using point (15,8) and slope m = [tex]-\frac{1}{57}[/tex]

[tex]y=mx+b\\8=-\frac{1}{57}(15)+b\\8=-\frac{15}{57}+b\\b=8+\frac{15}{57}\\b=\frac{8*57+15}{57}\\b=\frac{471}{57}\\b=\frac{157}{19}[/tex]

So, y-intercept b of new line is: [tex]b=\frac{157}{19}[/tex]

Equation of required line

Equation of line having slope m= [tex]-\frac{1}{57}[/tex] and y-intercept  [tex]b=\frac{157}{19}[/tex] is:

[tex]y=mx+b\\\mathbf{y=-\frac{1}{57}x+\frac{157}{19}}[/tex]

So, equation of a line through (15, 8) that is perpendicular to the line y =57 x −1 is [tex]\mathbf{y=-\frac{1}{57}x+\frac{157}{19}}[/tex]

Answer:

Step-by-step explanation:

Since we are not given the dimension. Let us say the shape of the patio is a rectangle with length 30m and width 18m.

Area of the rectangle = Length * Width

Area of the rectangle = 30 * 18

Area of the rectangle = 540m²

This means that 540m² of the patio costs $2276.35. To get the cost of each square metre of patio, we will say;

540m² = $2276.35

1m² = x

cross multiply;

540x = $2276.35

x = $2276.35/540

x = $4.22

Hence each square meter of patio will cost $4.22

Note that the dimension of patio was assumed. Same explanation can be employed for any dimension.

Answer:

8

Step-by-step explanation:

Measure of one interior angle of a regular polygon of n sides:

(n - 2)180/n

Measure of one exterior angle of a regular polygon if n sides:

360/n

"the interior angle is thrice the exterior angle"

(n - 2)180/n = 3 * 360/n

(n - 2)180 = 3 * 360

n - 2 = 3 * 2

n = 8

The number of sides is 8.

Answer:

p(x) as a product of linear factors. [tex]p(x)=(x+3)(x-2)(x+6)[/tex]

Step-by-step explanation:

(x+3) is the factor of polynomial [tex]p(x) = x^3 + 7x^2 - 36[/tex]

So, we can divide [tex]p(x) = x^3 + 7x^2 - 36[/tex] by (x+3) to find other factors

The division is shown in figure attached.

The quotient is: x^2+4x-12

Now factoring the quotient to find linear factors

[tex]x^2+4x-12\\=x^2+6x-2x-12\\=x(x+6)-2(x+6)\\=(x-2)(x+6)[/tex]

The factors are [tex](x+3)(x-2)(x+6)[/tex]

So, p(x) as a product of linear factors. [tex]p(x)=(x+3)(x-2)(x+6)[/tex]
