Answer:

y = m x + b equation for a straight line

m m' = -1 for perpendicular lines

Thus m' = -1/2 is required

Check:

-1/2 * -6 + 2 = = 3 + 2 = 5 = y for the last equation give

Ken and Mali put candies in bags to give away at Ken's birthday party. They started with an equal number of candies and put the

Valentin [98]

Answer:

The correct answer is 7.

Step-by-step explanation:

Let there be x number of candies in each bag filled by Ken and Mali.

Both Ken and Mali started with equal number of candies and put same number of candies in each bag.

Ken filled nine bags and had three candies left. Therefore total number of candies Ken had = 9x + 3.

Mali filled eight bags and had ten candies left. Therefore total number of candies Mali had = 8x + 10.

As both had equal number of candies in the beginning,

9x + 3 = 8x + 10

⇒ x = 10 - 3 = 7

Thus each bag contained 7 candies.

8. The graph below shows a dashed line on a coordinate plane. A right triangle is drawn so

Evgesh-ka [11]

Answer:

Option 2

Step-by-step explanation:

First, find the slope of the line of the graph using the points given as (5, -3) and (13, -9):

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-9 -(-3)}{13 - 5} = \frac{-6}{8} = -\frac{3}{4}$

Any of the triangle in the options given, whose opp side has the same slope value of -¾, is the triangle we are looking for.

Option 1: slope between the points (0, 2) and (3, -2).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{3 - 0} = \frac{-4}{3}$

Option 2: slope between the point (-7, 6) and (-3, 3).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 6}{-3 -(-7)} = \frac{-3}{4}$

Option 2 has the same slope as the one given in the graph. This is the answer.

Option 3: slope between the points (5, -1) and (2, -5).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-1)}{2 - 5} = \frac{-4}{-3} = \frac{4}{3}$

Option 4: slope between the points (2, -7) and (6, -4).

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-7)}{6 - 2} = \frac{3}{4} = \frac{3}{4}$

The answer is Option 2
