If u solve using the step by step equation process u will get the answer
Hope this explains it a little better
Answer:
F(-7,3) -> F'(-7,-3)
G(2,6) -> G'(2,-6)
H(3,5) ->H'(3,-5)
Step-by-step explanation:
If you are taking point (a,b) and reflecting it across the x-axis (the horizontal axis), your x value is going to stay the same because you want the point on the same vertical line as (a,b). The y-coordinate is going to be opposite because you want a reflection and the opposite of b will this give you the same distance from the x-axis as b.
So the transformation is this: (a,b) -> (a,-b).
All this means is leave x the same and take the opposite of y.
F(-7,3) -> F'(-7,-3)
G(2,6) -> G'(2,-6)
H(3,5) ->H'(3,-5)
Answer:
A. car needing both repairs is the intersection, which is P(A) * P(B).
92/200 * 136/200 = 391/1250 = .3128
B. car needing an alternator and not needing new brakes is the union, which is P(A) + P(notB) - P(A and B). We solved for P(A and B) in part A.
P(A) + P(notB) - P(A and B)
136/200 + 108/200 - .3128 = .9072
Answer:
30°
Step-by-step explanation:
BF is a straight line, so therefore it is equal to 180°
Because of this we know that COF is 150°, so therefor, to find BOC, we must subtract:
180° - 150° = 30°
