HELP HELP MEEEEEEE Determine whether the triangles are similar. If they are write similarity statement. Explain your reasoning.

Alex_Xolod [135]

Answer:

Step-by-step explanation:

every triangles degrees equal 180.

78+21=99

180-99=81

the smaller triangle

21+80= 101

180-101=79

so the degrees are different

How does y=mx+c? pls help its on my hw :0

Alika [10]

Answer:

a straight line with slope 3 and y-intercept (0,c) For instance y = 2x - 3 is a straight line with slope 2 and y-intercept (0,-3), and has this graph: For instance y = -4x + 1 is a straight line with slope -4 and y-intercept (0,1)

A line has a slope of -3/5 Which ordered pairs could be points on a parallel line? Check all that apply.

o-na [289]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

If two lines are parallel, then their slopes are equal

in this problem we have

the slope of the given line is $m=-\frac{3}{5}$

if ordered pairs could be points on a parallel line, then the ordered pairs must have a slope equal to $m=-\frac{3}{5}$

we are going to calculate the slope in each of the cases

case A) $(-8,8)\ and\ (2,2)$

substitute the values in the formula

$m=\frac{2-8}{2+8}$

$m=\frac{-6}{10}$

$m=-\frac{3}{5}$

$-\frac{3}{5}=-\frac{3}{5}$ --------> the ordered pair could be on a parallel line

case B) $(-5,-1)\ and\ (0,2)$

substitute the values in the formula

$m=\frac{2+1}{0+5}$

$m=\frac{3}{5}$

$-\frac{3}{5} \neq \frac{3}{5}$ --------> the ordered pair could not be in a parallel line

case C) $(-3,6)\ and\ (6,-9)$

substitute the values in the formula

$m=\frac{-9-6}{6+3}$

$m=\frac{-15}{9}$

$m=-\frac{5}{3}$

$-\frac{3}{5} \neq -\frac{5}{3}$ --------> the ordered pair could not be in a parallel line

case D) $(-2,1)\ and\ (3,-2)$

substitute the values in the formula

$m=\frac{-2-1}{3+2}$

$m=\frac{-3}{5}$

$m=-\frac{3}{5}$

$-\frac{3}{5} =-\frac{3}{5}$ --------> the ordered pair could be on a parallel line

case E) $(0,2)\ and\ (5,5)$

substitute the values in the formula

$m=\frac{5-2}{5-0}$

$m=\frac{3}{5}$

$-\frac{3}{5} \neq \frac{3}{5}$ --------> the ordered pair could not be in a parallel line

therefore

the answer is

$(-8,8)\ and\ (2,2)$

$(-2,1)\ and\ (3,-2)$
