How am I supposed to answer that if I can't get the graph to you?
20+(-3.05)+(-9.8)=20-3.05-9.8=7.15
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
<span>In a triangle the sum of two sides is always greater than the third side.
</span><span>A:12,9,21
</span><span>12+9 = 21
21 = 21 </span>⇒ no
<span>B:7,6,12
</span>7+6 = 13
13 > 12 ⇒ yes
<span>C:3,8,14
</span>3+8 = 11
11 < 14 ⇒ no
<span>D:23,13,37
</span>23+13= 36
36 < 37 ⇒ no
Answer: <span>B:7,6,12</span>
Answer:
Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:
