The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.
For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.
-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.
Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.
Answer:
0.528 because its just moveing the decimal point to the right.
just so you can understand better.
Answer:
2t + 4f = 100
t+f =42
Step-by-step explanation:
t= two point questions
f =four point questions
2t + 4f = 100
t+f =42
there are 34 two point questions and 8 four point questions
to solve multiply the second equation by -2
-2t -2f = -84
add this to 2t +4f = 100
2t + 4f = 100
-2t -2f = -84
-----------------------
2f = 16
divide by 2
f = 8
there are 8 four point questions
t+f=42
t+8 = 42
subtract 8
t = 34
there are 34 2 point questions
The answer is 4 hope this helps
