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:

y-x = -6

Step-by-step explanation:

Ok so you have 2y-6x=2

step 1: when you add 6 to 6x it cancels out the 6 then subtract 2 by six and get 2y-x=-4.

step 2: when you add 2 to 2y it cancels out the 2 then subtract -4 by two and get your answer.

1. a)

          2x    +     (-3)

   _______________

x  |      2x²    |    -3x      |

+  _______________

1  |       2x     |     -3       |

   -----------------------------

(2x - 3) (x + 1) = 2x² - 3x + 2x - 3 = 2x² - x - 3

b)

      x     +     2

   ____________

x  |   x²      |    2x    |

    ____________

3  |   3x     |      6    |

   -----------------------

(x + 2) (x + 3) = x² + 2x + 3x + 6 = x² + 5x + 6

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:

14.0

Step-by-step explanation:

when rounded to the nearest tenth, 13.989 is 14.0.

Answer:

Hey!

Your answer for your lil' sis is 14!

Step-by-step explanation:

The tenth column is the column directly after the decimal point...

GREATER THAN 5 = Round up...

LESS THAN 5 = Round down...

So in this case it is 9 SO WE ROUND UP

This makes it 14.0

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

Step-by-step explanation:

Answer:

b = 3

Step-by-step explanation:

Simplify 4b - 3b + 7 = 10

b + 7 = 10

Subtract 7 from both sides

b = 10 -7

Simplify 10 -7 to 3

b = 3

Answer:

BIG Bs

Step-by-step explanation:

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

d = liczba monet 10-centowych

p = liczba monet 5-centowych

Razem, Luca ma 40 monet:

d + p = 40

Jedna 10-centowa moneta ma wartość 10 centów, i jedna 5-centowa ma wartość 5 centów, więc

10d + 5p = 315

bo 3,15 euro = 315 centów.

Znajdź d i p :

(10d + 5p) - 5(d + p) = 315 - 5•40

5d = 115

d = 23

d + p = 40

23 + p = 40

p = 17
