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

Hope this helps!

Answer:

(6, -2)

Step-by-step explanation:

The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)

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    |

    ____________

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

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.

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

There is a common difference d between consecutive terms, that is

d = 12 - 0 = 24 - 12 = 36 - 24 = 48 - 36 = 12

This indicates the sequence is arithmetic with common difference 12

(b)

To obtain the next term add 12 to the previous term, that is

48 + 12 = 60 and 60 + 12 = 72

The next 2 terms in the sequence are 60 and 72

Answer:

if it easy math you do it = 12 times

Step-by-step explanation:

12 24 36 48 / 60 72 84 96  108 120 132 144

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

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
