9)The triangles are congruent as they share all sides as seen with the lines (SSS)
10) they are not congruent as they only share 2 sides not all 3
11)they are congruent by using the Angle Side Angle, they share a vertices
12)they are congruent, by using the side angle side
13)They are congruent by using side side side, one is shared between the two
14)they are congruent by using the angle side angle
2/3*1860= 1240
2/3 is equal to 66 2/3 %
Answer:
y=1/2x-2
Step-by-step explanation:
perpendicular lines have a neg. reciprocal for the slope.
for example:
in this equation y=-2x+1
-2 is the slope and the negative reciprocal would be 1/2
hence, the slop of our new line is 1/2
y=1/2x+b
we can substitute the coordinates given for x and y:
2=1/2(8)+b
2=4+b
-2=b
hence the new equation is y=1/2x-2
It is unlikely is the expected answer. (<em>c</em><em>o</em><em>r</em><em>r</em><em>e</em><em>c</em><em>t</em><em> </em><em>o</em><em>n</em><em>e</em><em>)</em>
Hope this helps.
Given: 
1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):
2. Distributive postulate:
The equation is
3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):
4. Subtraction property of equality:
a) subtract 6 from the first equation:
b) subtract 2 from the second equation:
