Write an expression having only two terms that is equivalent to 2x – 3. Explain how you wrote the expression and how you can check that it is equivalent

Answers

Answer:

The expression –3 + 2x is equivalent to 2x – 3. I know it is equivalent because for every value of x that is substituted in, the two expressions simplify to the same value. I took the expression and used the commutative property to not change the value.

An electronics store sells DVD players and cordless telephone. The store makes a $75 profit on the sale of each DVD player (d) and a $30 profit on the sale of each cordless telephone (c). The store wants to make a profit of a least $255.00 from its sales of DVD players and cordless phones. Write an inequality to model this situation.

Find an example to show how this situation could happen and one example showing how it could NOT happen. Make sure to justify your answer.

Answers

Inequality

75d + 30c ≥ 255

Examples

(1) If someone bought five DVD players and ten cordless telephones, the equation ((75)(5)+(30)(10)≥255) would be true.

(2) If the electronic store had a parcticularly bad day and they sold two DVD players and one cordless telephone, the equation ((75)(2)+(30)(1)≥255) would be false.

28.26m^2 (aka. 28.26 meters squared)

Step-by-step explanation:

The area of a circle is A=pi*r^2 where r is the radius of the circle.

Therefore, the area of the merry-go-round is 28.26 square meters

A rectangular prism has dimensions of 2 cm by 2 cm by 5 cm. What is its surface area? Explain also and thanks if anyone answers my question!

Answers

Answer:

The surface area is 48cm^2

Step-by-step explanation:

Given

Dimension: 2cm by 2cm by 5cm

Shape: Rectangular Prism

Required

Determine its Surface Area (A)

This is calculated as thus:

[tex]A = 2(lw + lh + hw)[/tex]

Where l, w and h are the dimensions of the given shape:

We can say:

[tex]l = length = 2cm[/tex]

[tex]w=width = 2cm[/tex]

[tex]h=height=5cm[/tex]

So:

[tex]A = 2(2 * 2 + 2 * 5 + 5 * 2)[/tex]

[tex]A = 2(4 + 10 + 10)[/tex]

[tex]A = 2(24)[/tex]

[tex]A = 2 * 24[/tex]

[tex]A = 48[/tex]

Hence, the surface area is 48cm^2

Please help. This is a solve for x problem!

Answers

Answer:

3/10 = x or 0.3 = x

Step-by-step explanation:

2.1 /  x + 1 4/5 = 3 / 10x

1. first cross multiply and solve it normally:

3 (x + 1 4/5) = (2.1) 10x

3x + 5 2/5 = 21x

-3x               -3x

5 2/5 = 18x

3/10 = x or 0.3 = x

these questions are kind annoying to solve because of the fractions, so if you can, use a calculator to solve them! its much easier!

hope this helps!

Answer:

x = 3/10 = 0.3

Step-by-step explanation:

{(2.1)/(x+1 4/5)} = 3/10x

x + 1 4/5 = x + 5/5 + 4/5 = x + 9/5

then:

(2.1)/(x+9/5) = 3/10x

10x*2.1 = 3(x+9/5)

21x = 3x+ 27/5

21x - 3x = 27/5

18x = 27/5

90x/5 = 27/5

90x = 27

x = 27/90

x = 3/10 = 0.3

For the line that passes through the points (0, 2) and (-6, 0), the x-intercept is and the y-intercept is

Answers

Answer:

The x-intercept is (-6, 0) and the y-intercept is (0, 2)

Step-by-step explanation:

We are already given points where x = 0 and y = 0

The x-intercept is when y = 0

The y-intercept is when x = 0

So the x-intercept is (-6, 0)

and the y-intercept is (0, 2)

1.Given the rotation of triangle ABC shown below, determine the counter-clockwise angle of rotation that occurred about point D. Show all relevant lines and measurements you made to determine your answer.
A) 180°
B) 90°
C) 130°
D) 50°
​

Answers

Answer:

D. 50º

Step-by-step explanation:

According to the image below attached, blue lines represents line segments [tex]DB[/tex] and [tex]DB'[/tex], the red line creates a right angle regarding [tex]DB[/tex] (90º), where green line creates a flat angle with the same respect (180º). The angle between [tex]DB[/tex] and [tex]DB'[/tex] is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

Find an equation for the line below

Answers

since the line is a straight line, the equation will be a linear equation and hence it will be y=mx+c

first, find the gradient (m) :
(y2-y1)/(x2-x1) = [1-(1)]/(-2-6)
= 2/-8
= -¼

sub. in y, x and m values to find c
1 = ¼(-2) + c
1 = -½ + c
c = 1 ½

hence the equation is y = -¼x + 1 ½
