Answer:
a) 0
b) -1/3
Step-by-step explanation:
It is y2-y1 over x2-x1 that is why you are messing up on your calculation
8+12/17-17 = 0
1+2/-3-6
= -3/9
=-1/3
hope this helps
Answer:
A: You plot these points (-3,4) (-3,6) (-5,6) (-7,4)
B: The transformation would be described as a reflection over the y axis
C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width
Step-by-step explanation:
So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)
So using the rule (x, y) → (-x, y) are new points would be:
(-3,4)
(-3,6)
(-5,6)
(-7,4)
This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
If you are looking for the new points, then this is what you do.
Add 2 to all of the x-coordinates
Subtract 4 from all of the y-coordinates
A(4, -6)
B(1, -3)
C(5, -2)
D(6, -4)
Hope this helps!
Divide 33 by 4, which is 8. Now do 8 times 7. 7 is the hours and 8 is the cost per hour, which is why me multiply. 8 times 7 = 56. Hope this helps
