A teacher spends $25.00 at a store for a pens and y notebooks. The store charges $2.50 for every pen and $5.00 for each notebook.
Which graph represents the situation

The equation has infinite solutions which lie on the graph of this equation.

We have the following equation -

y = 8 - 2x

We have to solve for the possible values of x and y for which the equation is satisfied.

The rearrangement of a mathematical equation is process of expressing a variable in a equation in terms of other variables, constants etc.

According to the question, we have the following equation -

y = 8 - 2x

Rearranging the equation -

y = - 2x + 8

Now, plot the equation on graph - (Graph is attached at the end)

All the coordinates on this line satisfy the equation → y = 8 - 2x.

Hence, the equation has infinite solutions which lie on the graph of this equation.

Answer:

x = -5

Step-by-step explanation:

First distribute the 5 on the right side of the equation.

10x - 35 = 15x - 10

Then subtract 10x on each side

-35 = 5x - 10

Then add 10 on each side

-25 = 5x

Divide 5 on each side to get x

-25 / 5 = -5

I hope this helps! :)

Answer:

[tex]\sf x=-5[/tex]

Step-by-step explanation:

[tex]\sf 5(2x-7)=15x-10\\10x-35=15x-10\\10x-35+35=15x-10+35\\10x=15x+25\\10x-15x=15x+25-15x\\-5x=25\\\cfrac{-5x}{-5}=\cfrac{25}{-5}\\x=-5[/tex]

Answer:

y = - 3x + 4

Step-by-step explanation:

Line is passing through the points (1, 1) & (0, 4)

Slope of line = (4-1)/(0-1) = 3/(-1) = - 3

Equation of line

y = mx + b

Here m = - 3, b = 4

y = - 3x + 4

Using point (1, 1)

y - 1= - 3(x - 1)

y = - 3x +3 +1

y = - 3x + 4

Answer:

Option A, B, and C.

Step-by-step explanation:

Given, 6x ≥ 3 + 4(2x - 1),

Solve to find the correct representations given in the options.

6x ≥ 3 + 4(2x - 1)

Apply distributive property

6x ≥ 3 + 8x - 4 (option B is correct) ✅

Add like terms

6x ≥ -1 + 8x

Add 1 to both sides

6x + 1 ≥ 8x

Subtract 6x from each side

1 ≥ 8x - 6x

1 ≥ 2x (option A is correct) ✅

Divide both sides by 2

1/2 ≥ 2x/2

½ ≥ x

½ ≥ x means all possible values of x are less than 0.5. representing this inequality on a graph, we would have the directed line starting at 0.5 moving towards our left.

This make option C correct.✅

Answer:

x=19/2

x=- 13/2

Step-by-step explanation:

multiply both sides by                                                         2 |2x -3|+10=26

move constant (10 to the right and change sign                |2x-3|=26-10

subtract the numbers                                                           |2x-3|=16

use absolute value (rewrite the absolute value                  2x-3=16

equation as two separate  equations one (+) and (-)           2x-3= -16

2x-3=16    move constant to the right

2x=16+3   add the numbers  

2x=19   divide both sides by 2

x=19/2

same steps with with second one

2x-2= -16

2x= -16 +3 move constant to the right change sign and add

2x= -13             divide both sides by two

x= -13/2

The  |   | are not (   ) .  They have different meaning , absolute value brackets. ok :)

Step-by-step explanation:

Quadratic Equation Solving

We have the equation:

[tex]8x^2-48x=-104[/tex]

Divide by 8:

[tex]x^2-6x=-13[/tex]

Now complete the squares so the left side is a perfect square of a binomial:

[tex]x^2-6x+9=-13+9=-4[/tex]

Factoring the perfect square:

[tex](x-3)^2=-4[/tex]

Taking the square root:

[tex]x-3=\sqrt{-4}[/tex]

The square root of a negative number is an imaginary number:

[tex]x-3=\pm 2\mathbf{i}[/tex]

The first , second and third sequence is arithmetic and the fourth sequence is geometric.

A sequence is a series of numbers such that each number follows a very specific rule or explicit function which determines its value. There are numerous types of sequence and series . But for this particular question we will need to know :

Let us now take each series of numbers and find the type of sequence it is:

sequence 1: 2, 4, 6, 8, 10

Common difference = 10-8 = 6-4 =2

So the sequence is arithmetic.

sequence 2: 5, 7, 9, 11, 13

Common difference = 13-11 = 7-5 =2

So the sequence is arithmetic.

sequence 3: 50, 25, 0, -25, -50

Common difference = 50-25 = - 25 - ( - 50) = 25

So the sequence is arithmetic.

sequence 2: 5, 7, 9, 11, 13

Common difference = 13-11 = 7 - 5 =2

So the sequence is arithmetic.

sequence 2: 1/3, 1, 3, 9, 27

Common ratio = 3 ÷ 1 = 27 ÷ 9 = 3

So the sequence is geometric.

The percentage of the T-shirt that are yellow will be 20%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

A T-shirt vendor sells yellow shirts and blue Shirts at a ratio of 1: 4.

The ratio of the yellow T-shirt is given as,

Yellow ratio = 1 / (4 + 1)

Yellow ratio = 1 / 5

Then the percentage of the T-shirt that are yellow will be given as,

P = [1/5] x 100

P = 0.20 x 100

P = 20%

The percentage of the T-shirt that are yellow will be 20%.

Step-by-step explanation:

Answer:

Radius = 9cm

Diameter = 18cm

Step-by-step explanation:

Remember that the diameter of a circle is the distance between two opposite sides (crossing the middle), and the radius is half of that - the distance from the middle to the outside.

the image shows that the diameter is 18cm, so we know that the radius is 18cm/2, which equals  9cm.
