Describe and correct the error in using properties of parallelograms.

Answer:

x = -10

Step-by-step explanation:

x/4=-2.5

multiply both sides by 4

x/4*4=-2.5*4

-2.5 times 4 is -10

x = -10

Answer:

Step-by-step explanation:

2(x + 15)⁰ + (3x + 20)⁰=180⁰

2x + 30⁰ + 3x + 20⁰=180⁰

2x + 3x + 30⁰ + 20⁰=180⁰

5x + 50⁰ - 50⁰=180⁰-50⁰

5x=130⁰

5x/5=130⁰/5

x=26⁰

Answer:

x should equal 26.

Step-by-step explanation:

since they are cointerior angles:

2 (x + 15) + (3x + 20) = 180

2 (x) + 2 (15) + (3x + 20) = 180

2x + 30 + (3x + 20) = 180

2x + 30 + 3x + 20 = 180

5x + 50 = 180

5x + 50 - 50 = 180 - 50

5x = 130

5 ÷ 5x = 130 ÷ 5

x = 26

Step-by-step explanation:

x+y = 10

1 + 9 = 10

2 + 8 = 10

3 + 7 = 10

4 + 6 =10

5 + 5 = 10

x - y = 2

4 - 2 = 2

8 - 6 = 2

10 - 8 = 2

12 - 10 = 2

22 - 20 = 2  

The value of x from the given equation is -2.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 4(x - 2) + 3 = 2x - 9.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

4x-8+3=2x-9

4x-5=2x-9

4x-2x=-9+5

2x=-4

x=-2

Therefore, the value of x from the given equation is -2.

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, obtuse triangle, equilateral triangle and right angled triangle.

Trigonometric functions are functions used to show the relationship between an angle of a right-angled triangle and the ratio of two side lengths. Below are some trigonometric function:

sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent.

Given the right angled triangle with angle x. and the hypotenuse y. We need to find the distance between the Earth and the shooting star.

d = distance between the Earth and the shooting star = adjacent side.

Therefore, the relationship between angle x, d and y can be gotten using the cos trig function.

cosθ = adjacent / hypotenuse

cos(x) = d / y

d = y * cos(x)

Answer:

The distance between 10 and 12 is 2.

But remember, don't forget to put the unit behind 2.

Step-by-step explanation:

Answer:

$97.70

Step-by-step explanation:

So to find percent

450/100= 4.5 ,4.5x15= 67.5

82/100=0.82 0.82x15= 12.2

120/100=1.2   1.2x15=18

So do 67.5+12.2+18=  $97.70

Answer:

Length of rectangular patio = 28 feet

Step-by-step explanation:

Given that:

Length of rectangular patio = x

Width of rectangular patio = [tex]2x-40\frac{3}{4}[/tex]

Perimeter of rectangular patio = [tex]86\frac{1}{2}[/tex]

Perimeter of rectangular patio = 2 (length + width )

Putting values in the formula

[tex]86\frac{1}{2}=2(x+2x-40\frac{3}{4})\\\\\frac{173}{2}=2(3x-\frac{163}{4})\\\\\frac{173}{2}=2(\frac{12x-163}{4})\\\\\frac{173}{2}=\frac{12x-163}{2}\\\\173 = 12x-163\\12x = 173 + 163 \\12x = 336[/tex]

Dividing both sides by 12

[tex]\frac{12x}{12}=\frac{336}{12}\\x=28[/tex]

Hence,

Length of rectangular patio = 28 feet

Answer:

Use Pythagorean Theorem to find the distance between the two points

[tex]x^{2} +y^{2} =r^{2}[/tex] where r is the distance between the two points

Δx = 6-4 = 2

Δy = 3-(-1) = 4

2²+4²=r²

4+16=r²

20=r²

√20=r

r=4.47

r=4.5

4.5÷2=2.25 (halfway)

∴The distance between the cafeteria and the bathrooms is 2.25 units

Hopefully you understand how I got this answer.  

Answer:

(5,1)

Step-by-step explanation:

So for this one we just find the length between the x values and the length between the y values and divide by 2 to find how far it will be ( if that makes sense.)

the distance between the two x values is 2 and the distance between the two y values is 4

2/2 = 1 and 4/2 = 2

then we subtract 1 from the x value and 2 from the y value ( using the coordinates of the cafeteria btw.)

6-1=5 and 3-2 =1 so the coordinates of the bathroom is (5,1)

Answer:

D

Step-by-step explanation:

your maximum "point" of the polynomial is the highest point that the curve makes which in this case is around x=-3.6 and y=17

The point of maxima for the given function is (-3.6, 17).

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

As per the graph of the function following conclusion are as below,

It has a maxima in second quadrant.

After the point of maxima, its value starts to decrease.

Then, it reaches it lowest value in fourth quadrant after which it increases again.

By examining the given options, the correct point of maxima can be found as (-3.6, 17).

Hence, the point of relative maxima for the graph can be evaluated as (-3.6, 17).
