Answer:

1/3 or 0.3 (repeating decimal)

Step-by-step explanation:

The subtraction the fractions gives 1/3.

The fractions include two parts, numerator and denominator.

Numerator: It is the upper part of the fraction, that represents the sections of the fraction.

Denominator: It is the lower or bottom part that represents the total parts in which the fraction is divided.

Given that are two fractions 1/2 and 1/6, we need to subtract them,

Firstly, equating the denominators,

1/2 = 6/12

1/6 = 2/12

Therefore,

1/2 - 1/6 = 6/12 - 2/12

= (6-2)/12

= 4/12

= 1/3

Hence on subtracting the fractions we get 1/3.

Answer:

y  = [tex]\frac{7}{6} x - 5[/tex]

Step-by-step explanation:

 Given expression:

        6x + 7y  = -42

To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.

Solution:

Equation of any straight line is given as;

        y  = mx + c

where x and y are the coordinates

                m is the slope

                c is the intercept

Let us now find the slope of the line;

          6x + 7y  = -42

              7y = -6x - 42

   divide through by 7 to give;

             y = [tex]-\frac{6}{7} x[/tex] - 6

The slope is  [tex]-\frac{6}{7}[/tex]

     A line perpendicular will have a slope of a negative inverse;

          - ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]

The answer is A.

Answer:

The answer is

[tex] \huge \frac{4}{5} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

From the question we have

[tex]m = \frac{11 - 7}{8 - 3} = \frac{4}{5} \\ [/tex]

We have the final answer as

Answer:

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Step-by-step explanation:

The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.

To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:

t=120+20*5

Solving, you get:

t=120+100

t=220

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Answer:

-2/15

Step-by-step explanation:

Apply the fractions formula for addition, to

− 45 + 23

and solve

( −4 × 3 ) + ( 2 × 5 ) 5 × 3

= − 12 + 10/15

= −2/15

Therefore:

−45+23= −2/15

Answer:

roots are not real

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

Then the nature of the roots can be found using the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then roots are not real

Given

9x² - 6x + 2 = 0

with a = 9, b = - 6, c = 2 , then

b² - 4ac = (- 6)² - (4× 9 × 2) = 36 - 72 = - 36

Since b² - 4ac < 0 then the roots are not real

Answer:

The lines are perpendicular. Option B.

Explanation:

Equation of the Line

One of the characteristics of the line is its slope. It can be determined in two ways:

* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.

* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The points are (3,4) and (7,3), thus the slope is:

[tex]\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}[/tex]

A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect

B. For two lines to be perpendicular, their slopes must meet the condition:

[tex]m1*m2=-1[/tex]

4*(-1/4)=-1

Both lines are perpendicular. Correct choice

D. Since choice B. is correct, this cannot be true. Incorrect
