y = x is a positively sloped line, meaning that it points to the right. It also has a y-intercept of (0,0).

y = -1/2x + 3 is a negatively sloped line, meaning that it points to the left. It has a y-intercept of (0,-3).

The correct graph is Graph A.

Answer:

#4          x = 3 ± i√31

                       2

Step-by-step explanation:

Solve by completing the square

  x² - 3x + 10 = 0    

  x² - 3x       =  -10

 x² - 3x + 9/4  =  -10 + 9/4       half of 3 and square the answer (half of 3 = 3/2  

                                                 and square the number   (3/2)²  = 9/4    

x² - 3x + 9/4  =  -31/4

[tex](x - \frac{3}{2} )^2 = \frac{-31}{4}[/tex]

[tex]\sqrt{(x-\frac{3}{2})^2 } =\sqrt{\frac{-31}{4} }[/tex]

[tex]x - \frac{3}{2} = \frac{i\sqrt{31} }{2}[/tex]  

x = 3/2 ±  i[tex]\sqrt{31}[/tex] /2

x = 3 ± i√31

          2

Answer:

23

Step-by-step explanation:

x + x + 1 + x + 2 + x + 3 + x + 4 = 110

5x + 10 = 110

x = 20

4th number = x + 3

20 + 3 = 23

Answer:

  -10

Step-by-step explanation:

Solving for y gives ...

  20y = 2x +6

  y = 2/20x +6/20 = 1/10x +3/10

The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.

The perpendicular line has a slope of -10.

Answer: The answer to this question is true.

The number of weeks that takes for her closet to have 50 pairs of shoes will be 15 weeks.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

Mindy claims 20 sets of shoes and consistently she buys two additional matches.

The first term is 20 and the common difference between the succession terms is 2. Then the equation is given as,

aₙ = a₁ + nd

aₙ = 20 + 2n

The number of weeks is given as,

50 = 20 + 2n

50 = 20 + 2n

50 = 20 + 2n

Simplify the equation, then we have

2n = 50 - 20

2n = 30

n = 30 / 2

n = 15

The number of weeks that takes for her closet to have 50 pairs of shoes will be 15 weeks.

The maximum height each tooth is 2.47cm.

The first step is to determine the maximum volume of a tooth.

Maximum volume of a tooth = volume of the block / number of teeth

81 cm³ / 20 = 4.05cm³

The formula to determine the height of a cone is:

Height = volume ÷ [tex]\frac{1}{3}[/tex]πr²

Where:

Height = 4.05  ÷ [tex]\frac{1}{3}[/tex] x [tex]\frac{22}{7}[/tex] x 1.25² = 2.47 cm

• Unknown number = a number that’s isn’t known yet

Question reads….

“ A [PRODUCT] of [a NUMBER] & 6 [is] 26”

RANDOM:

• Product is multiply/multiplication

• A number is unknown so we will label it as “n”

• 6 stays the same because nothing happened to it

• 26 is BEHIND the equal sign but nothing happens to it because nothing is being compared to it

Step-by-step explanation:because 50 divided by 2 is 25.

Answer:

40 units

Step-by-step explanation:

1) Find the side length of the square

Let the side be "s".

[tex]\rightarrow \frac{1}{2} \times s \times s = 50 \ \text{cm}^{2}[/tex]

[tex]\rightarrow s \times s = 50 \times 2[/tex]

[tex]\rightarrow s \times s = 100[/tex]

[tex]\rightarrow \sqrt{s \times s} = \sqrt{100}[/tex]

[tex]\rightarrow s = \±10[/tex]

[tex]\rightarrow s = 10 \ \text{units}[/tex]                                      (Side lengths can never be negative)

2) Find the perimeter of the square

[tex]\text{Perimeter of square = 4(s) = 4(10) = 40 units}[/tex]

Length in units:

Use phytogoras theorem or measure it by a ruler if your using a graph paper

AB = 5.65 units

AC = 5.83 units

CB = 1.41 units

Perimeter =5.65 + 5.83 + 1.41 = 12.89 units

Area = 1/2 * 1.41 * 5.65 = 3.98units

The equations of the lines given in the graph will be y = 3x and y =-5x -2.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

For line one the points are:-

( 1,3 ) and ( 0,0)

Slope = ( 0 - 3) / ( 0 - 1 )

Slope = 3

The equation will be,

y = 3x

For line two the points are:-

(-1,3) and (0,-2),

Slope = ( -2 - 3 ) / ( 0 + 1)

Slope = -5

The y-intercept will be,

y = mx +c

c = -2

The equation can be written as:-

y = -5x - 2

Answer: The answer is 1 1/9.

Explanation: Multiply the numerator by the reciprocal of the denominator(5/6 x 4/3). Cancel the common factor of 2, then multiply 5/3 x 2/3. The result is 10/9, which is an improper fraction which should be converted to the mixed fraction 1 1/9.
