Answer: Sometimes.


Step-by-step explanation:  The condition is not always true. As explained in the figure attached, In triangle AB, line MN is not parallel to the side BC but in triangle DEF, line PQ is parallel to the side EF. We can see that triangle AMN is not parallel to triangle ABC but triangle DPQ is similar to triangle DEF. Thus, for the triangles to be similar, the line should be parallel to the third side of the triangle with which the line is not intersecting.

Thus, it is sometimes true.

#2 Find the slope given the points (6,-12) and (15,-3)*
castortr0y [4]

Greetings :)

To find slope of two points we will need to use this equation:   \frac{y^2-y^1}{x^2-x^1}

 x^1     x^2     y^1    y^2  

( 6 , -12 ) ( 15 , -3 )

Now let's replace the equation with the numbers. (it will be a fraction).

\frac{-3-(-12)}{15-12}         =         \frac{9}{9}

The equation equals 9 over 9, which also equals 1.

The slope of the line is 1.

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?
m_a_m_a [10]

Answer:9 nickels and 19 dimes.

Step-by-step explanation:

Let n be the number of nickels Kay has.

Let d be the number of dimes Kay has.

Value of 1 nickel is $0.05

Value of n nickels is $0.05n

Value of 1 dime is $0.1

Value of d nickels is $0.1dn

Given that Kay has a total of 28 coins.

So,n+d=28                                                ...(i)

Given that Kay has a total value of $2.35

So,0.05n+0.1d=2.35                                 ...(ii)

Using (i) and (ii),

0.05n+0.1(28-n)=2.35\\0.05n+2.8-0.1n=2.35\\2.8-2.35=0.05n\\0.45=0.05n\\n=9

d=28-n=28-9=19
