Answer:
The answer is option C : 5%.
Step-by-step explanation:
Jack typed 80 words per minute when he enrolled in a typing course.
His typing speed increased by 3% two weeks into the course.
At the end of the course, Jack was able to type his entire 1, 680 word document In 20 minutes.
Hence, the percent of increase in his typing speed from the beginning of the course to the end is given by:
=5%
Therefore, the answer is option C : 5%.
The equation that does not justify the similarities of both triangles is:
<h3>Similar triangles</h3>
Similar triangles may or may not have congruent sides.
The triangles are given as:
The above means that, the following sides are similar
- Line segments PQ and ST
- Line segments QR and TR
- Line segments PR and SR
So, the equation that does not justify the similarities of both triangles is:

Answer:
the origin is point (0,0)
Step-by-step explanation:
part B) point (-1,1) you move one point to the left front the origin and 1 step upwards
point (1 ,-1.5) move one point to the right and 1 halves downwards
point (2,fraction 1 over 4) move two point to the right and a quarter upwards
Answer:
Answer is 12 isnt it
Step-by-step explanation:
12×4=48
48+9=57
Y=3x-5
y-3x=-5
Times 2 from both side
y(2)-3x(2)=-5(2)
2y-6x=-10
Times negative from both side
(-)2y-6x(-)=(-)-10
-2y+6x=10
or
6x-2y=10
6x=2y+10
6x-2y=10
Furthermore, we see that both equation have the same 6x-2y=10 which means that both of them have infinity solutions, not a solution. Hope it help!
