6 0

Answer:

-6

Step-by-step explanation:

The pattern here is that you substract 15 every time you move a number (left to right) , therefore: 9-15 = -6

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below =)

Line L passes through the points (1, 1) and (7, 8). What is the slope of a line that is perpendicular to line L?
asambeis [7]

When a line passes through the two points (x_{1},y_{1}) and (x_{2},y_{2}) , its slope is given by the formula m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this question, a line L passes through the points (1,1) and (7,8)

So, its slope is given by m=\frac{8-1}{7-1}

m=\frac{7}{6}

When two lines are perpendicular, then the product of their slopes is -1.

Since, the slope of the line L is \frac{7}{6} , so the slope of the line which is perpendicular to the given line L is \frac{-6}{7} as the product of \frac{-6}{7} \times \frac{7}{6}=-1.

The given line passes through the points (0, −3) and (2, 3).
Alex

Answer:

The equation would be y + 1 = 3(x + 1)

Step-by-step explanation:

In order to find the equation of this line, we have to use the slope formula to find the slope.

m (slope) = (y2 - y1)/(x2 - x1)

m = (3 - -3)/(2 - 0)

m = (3 + 3)/(2 - 0)

m = 6/2

m = 3

Now that we have that, we can use it along with the second point to put into the point-slope equation.

y - y1 = m(x - x1)

y - -1= 3(x - -1)

y + 1 = 3(x + 1)

The Hickory Stick has a selection of 3 meats and 6 vegetables. How many different selections of one meat and one vegetable are p
valentina_108 [34]

The <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.

Since the Hickory Stick has a selection of 3 meats and 6 vegetables, the number of ways we can select <u>one </u>meat out of 3 is ³C₁ = 3.

Also, the number of ways we can select <u>one </u>vegetable out of 6 is ⁶C₁ = 6.

So, the total number of selections of <u>one</u> meat and <u>one</u> vegetable is ³C₁ × ⁶C₁ = 3 × 6

= 18 selections

So, the <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.
