Answer:
5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x
y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.
1y + 1y + 3y = 5y
4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12
Now you have to put all the final terms together to get: 11x + 5y +12
Step-by-step explanation:
Answer:
Step-by-step explanation:
b=boy
a= a on the exam
b=15
b∩a=6
b'∩a=3
b'∪a'=?
b'∪a'= b'+a'-b'∩a'
a= b∩a+b'∩a (law of total probability) = 9
a'= 25-9 = 16
b'= 25-15= 10
16+10-7=19
19/25= .76
If the question is y = blank(x) + blank (I can’t see the left of the equation
Then the answer is y = 2x + -4
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.
